Connections1ESC/Radio Calibration2Program your ESC with the transmitter stick/trigger1Factory Reset3Start-up201Introduction06ESC Setup07ESC Programming(Those "black backgroud and white text" options are the factory default settings)08Explanations for LED Status09Explanations for Protections10Trouble Shooting• During the Start-up Process1) The RED LED flashes one time per 2 seconds and the motor beeps “B,B,B,B,...“ at the same time indicating the ESC doesn’t detect any throttle signal. 2) The GREEN LED flashes “Number” times indicating the number of Lipo cells you have connected to the ESC.• In Operation1) The RED LED & GREEN LED die out when the throttle stick is located at the neutral position.2) The RED LED turns on solid when your boat runs forward. The GREEN LED will also come on when moving the throttle stick to the full throttle (100%) endpoint. 3) The RED LED turns on solid when you reverse your boat.• When Some Protection is Activated1) The RED LED flashes a short, single flash that repeats (☆, ☆, ☆) indicating the low-voltage cutoff protection is activated. 2) The GREEN LED flashes a short, single flash that repeats (☆, ☆, ☆) indicating the ESC thermal protection is activated.• Low-voltage Cutoff ProtectionThe ESC will not cut off the output but reduce it to 50% when the ESC detects the battery voltage goes below the preset cutoff voltage for 1 second. The RED LED will flash a single flash repeatedly every time when you release the throttle trigger to the neutral position. • ESC Thermal ProtectionThe ESC will not cut off the output but reduce it to 50% when the ESC internal temperature goes above the preset value. The GREEN LED will flash a single flash repeatedly every time when you release the throttle trigger to the neutral position. The ESC will resume normal output after the temperature goes below 80℃(176℉).Note 3: Temperature here means the internal temperature of the ESC. It’s often 60 Fahrenheit degrees higher than the heat-sink temperature (of the ESC). • Throttle Signal Loss ProtectionThe ESC will cut off the output after it fails to detect any throttle signal for 0.1 second. The motor will immediately resume rotation after the signal is re-detected. We recommend activating the “Fail Save” function of the radio system and set it (F/S) to “Output OFF” or set its value to the “Zero-Speed Position” to ensure the motor can be stopped when there is no signal received from the transmitter.please refer to the user manual of Hobbywing’s WiFi Express.• Please keep the propeller away from your body and other objects.1. Running ModeOption 1: Forward OnlyThe boat can only go forward in this mode. This mode is usually for racing. Option 2: Forward/ReverseThe boat can also go backward in this mode. This mode is applicable to most applications. (Note: Please ensure that the drivetrain of your boat can reverse. Because the drivetrain with flexible shaft can only go in one direction, the reversal may damage the flexible shaft.) 2. Lipo CellsThe ESC will automatically calculate the number of Lipo cells you have plugged in as per the battery voltage it detects, if the voltage is below 8.8V, it will be identified as 2S Lipo; if the voltage is from 8.8V to 13.2V, it will be identified as 3S Lipo; and so on. If a battery pack is not fully charged before connecting it to the ESC, miscalculation may occur like a not fully charged 6S Lipo may be identified as a 5S Lipo. This may cause the Low-Voltage Cutoff Protection function abnormal. Therefore, you need to ensure that the battery you connect to the ESC is fully charged. If you only use one particular Lipo battery, we recommend manually setting the “Lipo Cells” to the specific option instead of using “Auto Calc.”, so the Low-voltage Cutoff Protection can always function properly. 3. Cutoff VoltageWhen using a LiPo battery, you need to set a proper cutoff voltage for your battery as per its discharge C count and the load. The ESC will monitor the battery voltage all the time, LVC(Low Voltage Cutoff) protection will be activated and the output power will be remarkably decreased when the battery voltage goes below the programmed cutoff voltage.A. How to calculate the cutoff voltage: cutoff voltage=cutoff voltage per cell * cell count. For instance, when setting the cutoff voltage per cell at 3.2V, the total cutoff voltage for a 3S Lipo should be 3.2V*3=9.6V.B. After entering the Low-Voltage Cutoff Protection: when the LVC protection is activated, the ESC will not cut off the output but reduce it to 50%. The RED LED will flash a single flash repeatedly every time when you release the throttle trigger to the neutral position. Please get your boat back immediately when this happens and change another fully charged battery. Warning! If you ignore the “hint” and keep using the battery will get your battery irreversibly damaged.C. When using a NiMH battery: because NiMH batteries don’t need this LVC protection, so you can set the “Cutoff Voltage” to “Disabled”. When you find the power is remarkably decreased in sailing, you only need to get the boat back immediately. 4. ESC Thermal ProtectionThe ESC will not cut off the output but reduce it to 50% when the ESC internal temperature goes above the preset value. The GREEN LED will flash a single flash repeatedly every time when you release the throttle trigger to the neutral position.The ESC will resume normal output after the temperature goes below 80℃ (176℉).5. BEC Voltage Option 1:6.0VIt’s applicable to ordinary servos. Do not use this option with high voltage servos; otherwise your servos may not function normally due to insufficient voltage. Option 2:7.4VIt’s applicable to high voltage servos. Do not use this option with ordinary servos; otherwise your servos may be burnt due to high voltage.6. Start Mode / PunchYou can choose the punch from level 1 (very soft) to level 5 (very aggressive). In addition, “level 4” and “level 5” have strict requirement on battery’s discharge capability. It may affect the starting-up if the battery discharges poorly and cannot provide large current. The boat stutters or suddenly loses power indicating the battery’s discharge capability is not good, then you need to lower down the punch.7. Timing / General Timing This item has three effects:• Make the ESC compatible with different motors. Some motors may function abnormally with the default Timing (15 degrees), you need to adjust the ESC timing to a proper degree and then they will work fine.• Fine tune the output power of the motor. The bigger the ESC timing, the higher the motor speed , and the more electric energy it will consume. • Make the motor operate at the optimum efficiency point through adjusting this item. 8. Turbo AccelerationIf the Turbo Acceleration is triggered, the ESC will immediately activate the programmed Turbo Timing (refer to the 9th programmable item). The motor can output greater power (than in normal condition). This function is mainly used on long waterway or when driving the boat out of corner. Note 1:• Turbo Acceleration signal wire is usually plugged into CH3 or CH4 on receiver, and the amount of the valid signal must over 80% of the maximum travel volume (usually the maximum travel volume is 100%) .• With a pistol-style transmitter: CH3/CH4 is often controlled by a button (on the transmitter), you only need to press the button to activate the Turbo Acceleration. With a board-style transmitter: If CH3/CH4 is controlled by a switch, then push the switch to the up/down position can deactivate/activate the Turbo Acceleration.• When the programmed General Timing is bigger than Turbo Timing (for example,. the General Timing is set to 22.5 degrees and the Turbo Timing is 15 degrees), there won’t be any effect even if Turbo Acceleration is enabled. Please ensure that the Turbo Timing value must bigger than General Timing if you want to use Turbo Acceleration function. 9. Turbo TimingTurbo Timing is adjustable from 0 to 26.25 degrees. With the Turbo Acceleration is enabled, the ESC will activate the corresponding Turbo Timing after it receives Turbo Acceleration signals.10. PWM frequencyThe increase of PWM frequency can make the motor running smoother and the noise lower, but it will also make your ESC hotter. If the motor has no unsmooth/uneven issue, we recommend selecting the default setting (8KHz).Four steps to program your ESC with a transmitter:Entering Programming Mode —> Selecting Programmable Item(s) —> Selecting Parameter Value(s) /Option(s) —> Exiting Programming Mode.03Features• Light-weight perfectly meets users' strict requirement against the weight of competition marine ESCs.• No extra precaution is needed because of its outstanding water resistance (injection molding for Pro 160A & nano-coating for Pro 120A, it can be immersed in water). (Note: It’s necessary to fully dry all the connectors after use if they are immersed in water)• Internal switch-mode BEC with switchable voltage of 6V/7.4V and cont./peak amp of 4A/8A for easily driving big torque servos and high voltage servos.• HOBBYWING-patented heat-conductive copper bars combined with water cooling heatsink and MOSFETs with extremely low internal resistance greatly improve the current endurance and reliability of the ESC.• Advanced firmware guarantees the user the excellent control feel and “abundant” programmable items for different competition environments.• Innovative Turbo Acceleration function (which enables the Turbo Timing) can make the motor unleash the maximum power to speed up, and leave all rivals far behind in a moment. • “Forward Only”& “Forward/Reverse” running modes.• Multiple protections: low-voltage cutoff protection, ESC thermal protection, and fail safe (throttle signal loss protection).• 8 Timing options perfectly match with various of brushless motors.• Advanced programming via portable multifunction LCD program box or WiFi module (sold separately).• Firmware upgrade via HOBBYWING multifunction LCD program box or WiFi module (sold separately).1. Water Cooling Tube Connecting (Silicon tube needs to be provided by users.)The aluminum water cooling tube (outer diameter = 5.5mm) has been pre-mounted on the ESC heatsink at factory. Please connect the silicon tube to the aluminum water cooling tube. 2. Motor WiringThere is no polarity on the A/B/C wires between ESC and motor, so do not worry about how you connect them initially. You may find it necessary to swap two wires if the motor runs in reverse.3. Receiver Wiring1) How to connect the throttle control cablePlug the throttle control cable (also called Rx cable) on the ESC into the throttle (TH) channel on receiver. The RED wire in the throttle control cable will output the BEC voltage of 6V/7.4V to the receiver and servo, so please do not connect any additional battery to the receiver. 2) How to connect the Turbo Acceleration signal wire (/single YELLOW wire)Plug the Turbo Acceleration signal wire of the ESC into any unoccupied channel (for example, CH3/CH4) on your receiver. 4. Battery WiringProper polarity is essential here! Make absolutely sure positive (+) of ESC connects to positive (+) of battery, and negative (-) of ESC connects to negative (-) of battery when you plug in your battery! If reverse polarity is applied to your ESC from the battery, it will damage your ESC. This will NOT be covered under warranty!Move the throttle trigger/stick to the Zero-Speed throttle position, and then turn on the transmitter.1. Connect a battery pack to the ESC; the motor will beep “Number” times to indicate the amount of Lipo cells you have plugged in. Please ensure the cell count is correct. If the motor only beeps one time, it means the Low-Voltage Cutoff Protection is disabled. This “Disabled” option is only applicable to NiMH battery packs.2. 1 second later, the motor will beep a long beep “B—“to indicate the ESC is ready to run. If the throttle trigger/stick is not at the Zero-Speed throttle position, the motor will keep beeping a short beep “BBB……” until the throttle trigger/stick is moved to the Zero-Speed throttle position.3. Increase the throttle amount, the motor spins up.USER MANUALSeaking Pro 120A • Seaking Pro 160ABrushless Electronic Speed Controller 04Specifications05Begin to Use a New ESCStep 1: Entering Programming Mode1. Turn on the transmitter, move the throttle stick to the top position (/full throttle position), connect a battery pack to the ESC, and the motor will beep “BB“ (to indicate the full throttle position has confirmed).2.

bfriendit无线鼠标的使用及故障排除方法

Bfriendit无线鼠标的使用及故障排除方法
小编:傅斌
小编这次讲得基础的,在我们的世界,太多“然并软”的东西,小编这次讲我们入门的,大家一起进步一起学习!
世界那么大,我们来瞅瞅,无线鼠标长啥样及排除故障;
如下图无线鼠标基础东西:
小编想问了,长这样的无线鼠标不能使用了,会那么问题呢?
一.直接不能使用了,动都动不了?
1.确保键盘和鼠标的电池都已经装好,鼠标的开关打开,接收器插到电视或者电脑的USB口上。
2.检查电池是否电量足够。
二.无线鼠标反应不灵敏,键盘反应慢?
1、检查鼠标的DPI是否调节到2500,也就是按一下中间的DPI键,感觉一下速度,不行再按一下。
2、把接收器在电视上换一下USB口,有些USB口不连着主板,导致供电不足,也会影响速度。
3、在鼠标下面加个鼠标垫,更好操作。
4、要是使用一段时间或者几个月以后出现这个问题,可能是您的电池供电不足了,这是就需要更换新电池就可以解决的。
三.无线键鼠一般使用多远距离合适?
1、一般无线键鼠厂家设定的理论距离都是10-30米;但是一般我们正常使用都是2-4米,这是我们视觉能够着的距离,这个距离内使用都会不错的。
Bfriendit无线鼠标的数据参数:
四、我不用了无线鼠标和键盘需要关闭吗?
1.一般无线鼠标都是带开关的,不用了一段时间自己会休眠,但是还是建议不用了关掉电源开关,以免费电和影响鼠标使用寿命;键盘目前的设计都是不带开关的,也较为省电,一般只有您按下去按键才会耗电的,所以这个不用考虑耗电的问题,一般的键盘都是一节电池就可以的,部分是2节电池。

The respondent does not have a direct contractual relationship with Zhang Hua. Zhang Hua had an oral contract to remove the high-voltage meter cabinet with Binhai No. 2 Construction Installation Company on June 10, 2008. He was assigned by Binhai No. 2 Construction and Installation Company and therefore has no direct contractual relationship with the respondent.2. Binhai No. 2 Construction and Installation Company should be responsible for compensating Zhang Hua for the following reasons. Firstly, according to PRC laws and relevant judicial interpretations, Binhai No. 2 Construction and Installation Company shall be responsible for any injury employees suffered in the contract performance. Secondly, Zhang Hua seriously violated the operational procedure in removing the high-voltage meter cabinet and failed to pay due attention thereto.3. The respondent shall not be responsible for compensating the injuries of Zhang Hua. According to the General Principles of the Civil Law, any person engaged in highly dangerous operations shall be responsible for compensation. In this case, the respondent entered into a contract with Binhai No. 2 Construction and Installation Company, whereby the source of high danger shifted to Binhai No. 2 Construction and Installation Company. Binhai No. 2 Construction and InstallationCompany became the subject of the dangerous operation, and therefore any damages caused in the contract performance by Binhai No. 2 Construction and Installation Company have no connection with the respondent.Therefore, Binhai People's Hospital is not liable for compensating Zhang Hua. We hereby request the court to reject the plaintiff's action according to law.To:Binhai City Intermediate People's CourtRespondent: Binhai People's CourtDate: May 10th, 20111.
