FTD is a configurablesoftware feature that is available in application list. Field Test Display is useful for testing mobilephones during development or for verifying the operation of the network.2 USING THE FIELD TEST DISPLAYS2.1 GeneralWhen the Field Test Display is active, the phone can be used in a similar way than without it. Whenapplication key is pressed FTD will stay on background and it can be activated again by pressingapplication key for about one second and after that select.During proper power off (use of power key or RE-CHARGE indication) some valuable data (e.g. thenumber of current field test display) is stored onto the permanent memory. Next time when phone ispowered on the lastly selected field test display will be automatically re-activated. When Field TestDisplay is active, normal signal and battery level bars are visible.2.2 ActivatingField Test DisplaysThe Field Test Display is located in other folder and can be activated as follows:1. Press application key2. Scroll in the application list to other folder and from there field test display item3. Press the Options button and Open or press rocker to select2.3 Exiting Field Test DisplaysTest display can be deactivated by pressing Exit key or1. Press the Options button2. Choose Exit2.4 Field Test Display modes2.4.1 Modes belonging in the use of the displaysThere are two Field Test Displays modes:• Execute mode• Data display modeDifferent modes are marked in this specification as follows:Execute mode: Data display mode:************************** +++++++++++++++++++++++++++* Execute display * + Parameter 1 aaaa +* With this display it is * + Parameter 2 bbbb +* possible to reset * + Parameter 3 cccc +* registration / mobility * + Parameter 4 dddd +* counters.

The data displaymode displays data with parameter text. The rocker key (<,>^,v) offer an easy way to switch toanother test displays without using the options menu. Rocker (<,>) can be used to change differentdisplay groups, e.g. from Group1: GSM signalling displays to Group 6: GPRS signalling displays.Rocker (^,v) can be used to change different data displays within one group.3 INFORMATION ON THE DISPLAYSLength of a field is shown in the display picture by amount of the letters. Two notations are currentlyused. Examples of an old and new notations:Old notation New notationField with 5 letters, field name a aaaaa a(5)Field with 4 letters, field name h Hhhh h(4)If a value is not available, 'x' is shown for all the digits. If data to be displayed is shorter than the fieldreserved to show that data, text is aligned left and numbers right.As so many field test display as possible are defined to be common. The rest of the displays aredivided based on protocol (GSM, WCDMA). All displays are divided into different groups based onthat and in every group display numbering starts from 01. Format of the field is shown in Formatcolumn using next symbols:Symbol DescriptionDW:D double word, 32bit value shown in decimalDW:H double word, 32bit value shown in hexadecimalW:D word, 16bit value shown in decimalW:H word, 16bit value shown in hexadecimalB:D byte, 8bit value shown in decimalB:H byte, 8bit value shown in hexadecimalS String01.08.2004Group 01: GSM Signalling displays, which can be visible to network operatorsThe network operators can activate these signalling displays. Before field test displays are visible,mobile has to be modified. With the normal production mobile, field test displays are not working.Display 01.01: Information of the serving cellData Display:++++++++++++++++++++++++++++ Channel num abbb ++ Rx level ccc ++ Tx power lev ddd ++ GPRS attach qq ++ TS / TA e ff ++ Rx / R time g mmmm ++ C1 / C2 nnn ppp ++ Band/ CHty rr oooo ++ Amr U/AMR D x y ++++++++++++++++++++++++++++Abbr.

The meaningof different values of the parameter is specified as follows:Value Meaning0 (00) Normal reporting of the six strongest cells, with known and allowed NCC part of BSIC,irrespective of the band used.1 (01) The MS shall report the strongest cell, with known and allowed NCC part of BSIC, in eachof the frequency bands in the BA list, excluding the frequency band of the serving cell.The remaining positions in the measurement report shall be used for reporting of cells inthe band of the serving cell.

小米手机如何进入工程模式
小米手机如何进入工程模式
随着手机行业的开展，各种智能机都在我们身边。

每台手机都有属于它自己的独一无法的IMEI号，也可以说是该手机的身份证。

小米手机拥有属于自己的工程界面，那小米手机的工程模式该怎么进入呢?下面和jy135一起看看吧!
小米手机的工程模式
在小米手机的拨号界面依次键入“*#*#6484#*#*”就可以立即进入工程模式了。

其实在这个模式下，我们无非就是可以对手机局部硬件进行一系列的测试，比方说LED灯、光线感应器、陀螺仪感应器等等。

进入到每个环节下，都会有更加详细的测试工程，这里笔者就不再多说了。

对于手机的.工程模式而言，普通用户几乎是用不到的，所以厂家几乎就不会在说明书甚至官网上给出进入该模式的方法。

当然，倘假设大家的手机在某些环节出了问题的话，在送修之前最好还是进入工程模式测试一下，这样在送修之时告知维修人员，对未来手机的维修进度还是有一定帮助的。

在座的朋友，你们记住这组口令了吗?。

华为手机进入工程模式的方法

华为手机进入工程模式的方法
华为手机进入工程模式的方法
第一种指令：拔号盘输入*#*#6130#*#*
这个相当于安卓2.3时代*#*#4636#*#*指令。

可查看当前网络信号、电池信息，设置网络类型，还可以查询手机上各应用的使用情况。

其中点击“手机信息”后sim卡在哪个卡槽就选“账户1/2”，想要信号固定在3G的选网络类型为“WCDMA preferred”。

第二种指令：拔号盘输入*#*#14789632#*#*
很重要的`一条指令。

尤其是其中的“单板基本信息的查询”-“器件型号查询”，你的畅玩由哪些配件堆砌而成一目了然。

小伙伴们可以以此比较各个批次是否有什么差别，还可以鉴别手机是不是原厂机器。

第三种指令：拔号盘输入*#*#1673495#*#*
包括LOG、USB端口设置及电池基本参数检测，以及SD卡升级，自己揣摩一下，不懂的可别乱点哦!
第四种指令：拔号盘输入*#*#121314#*#*
这个是手机功能测试，也就是对畅玩的一次全身体检，几乎所有部件的单项测试都包含在内，并且能够保存结果到SD卡。

华为手机基本上都是采用的安卓系统，该工程模式下能对手机的整机进行测试和设置，是非常实用的功能，但对于没有相关经验的人来说，也是个相当危险的功能，设置出错可能会造成手机某些功能失效，严重的直接瘫痪手机都是可能的，因此在修改工程模式下相关选项时一定要慎重哟。

巧用手机工程模式

巧用手机工程模式作者：来源：《电脑爱好者》2013年第09期工程模式进入有方之所以很少会有人使用手机的工程模式，主要是因为该模式是厂商用来升级系统或者更改系统关键参数使用的，对于用户使用手机没有任何实际作用，所以手机厂商都不会公布自己品牌手机的工程模式进入方法。

此外因为各个手机厂商的工程模式进入方法不同，很少有人能记住自己要买的手机进入工程模式的方法。

虽然说手机工程模式对用户使用手机没有任何作用，但如果能够灵活地应用该模式，那么在购买手机的时候就可以进入该模式对手机的硬件以及功能进行检测，非常方便。

各品牌手机进入工程模式方法三星手机 *#0*#HTC手机 *#*#4636#*#*索尼手机 *#*#7378423#*#*LG手机 3845#*880#中兴手机 *983*70#华为手机 *#*#2846579#*#*联想手机 #72728439#酷派手机 *20060606#大家在确定打算购买的手机品牌后，首先记下进入手机工程模式的串号，验机过程中在拨号界面输入相应品牌的串号就可以进入工程模式。

这里要提醒大家的是，三星和谷歌合作推出的“太子”系列无法使用该串号进入，另外LG手机每一个型号产品进入工程模式的串号也有差异，用户需要将最后三位数字换成所要购买手机的型号中的数字部分进入。

比如说要购买LG P990，那么进入工程模式的串号就是3845#*990#。

工程模式操作方法正确输入串号之后，手机会自动跳转进入工程模式，小编就以自己的三星GALAXY Note 为例告诉大家如何使用功能模式进行手机主要功能的测试。

首先需要检测的是手机屏幕是否有亮点、坏点等情况，在三星手机工程模式菜单最上排三个选项就是检测屏幕坏点，点击后屏幕会分别呈现全红、全绿和全蓝三种模式（有些手机还有全黑和全白画面）。

如果手机屏幕不合格，会在纯色画面下暴露无遗。

当然如果大家要检测亮点，在手机全黑画面下看得最清晰。

虽然三星没有提供全黑画面，但大家可以打开手机拍照功能，然后遮住手机摄像头拍下一张照片，同样可以检测。

所有安卓手机进入Recovery模式的方法

所有安卓手机进入Recovery模式的方法Recovery模式是手机系统的一个工程模式,作用是恢复和清除。

用户进入这个模式之后，可以对当前系统的一些数据进行清除、恢复出厂设置、备份还原系统等操作.1、进入Recovery模式前，请先确认你手机已经备份了短信和通讯录.安卓手机一般都自带了这个备份工具，自己在程序菜单栏里好好找一下，实在找不到的话,可以度娘下载一个。

2、进入Recovery模式前，请先确认你手机上的“比如QQ、陌陌聊天记录、游戏存档"等已备份。

3、进入Recovery模式前，请先关闭你的手机(手机关闭不了的,可以直接拔电池再插回）4、关机状态下，左手按住音量减键不松开,右手按住开机键不松开（你愿意的话，单手操作也行，只要别把手机弄摔了就行），等待20秒会出现绿色小机器人图标（有些机型可能不显示),接着会自动进入Recovery模式,如下图所示。

5、由于各手机厂商开发技术不同，上面的Recovery模式界面也是不同，不过幸好都是大同小异的，大家摸索多几次就会上手了。

6、安卓手机运行久了，系统可运行内存就会越来越少（哪怕你不上网不玩游戏不看电影，只打电话和发信息，也是会占用内存的）,内存少了，系统运行速度就会越来越慢，直到频繁死机、白屏和经常程序无响应这种情况出现为止。

就算你重启手机也是不起作用的，所以我们需要用到Recovery模式内的双W功能。

双W就是上图第3、4行内的Wipe开头的一段英文,中文解释为“清除系统缓存和恢复出厂设置”,效果嘛。

类似电脑的重装系统。

7、在Recovery模式内，是不能用手点击屏幕来进行相关操作的(不信的话，大伙可以试试，呵~），我们只能利用手机表面的按键来操作,比如“音量加键、音量减键和开机键"（分别代表向上翻页、向下翻页和确认操作）。

8、请分别用音量加、减键和开机键来执行双W操作，双W完会回到上图的界面，再选择“reboot system now"（重启手机)即可，你就会发现手机的运行速度一下子快了很多，玩游戏、上网页都比之前流畅了很多。

NOKIA工程模式详细介绍

用Nokia Logo Express开启工程模式：如下载后没有开启工程模式的选项，就用下面的方式让此功能出现：执行reg edit到HKEY_CURRENT_USERSoftwareVB and VBA program settingsNokia Lo go ExpressProperties，新增一个字符串名字是"Tools"，值是"243"，然后进Nokia Logo Express，会多一个Tools的选单。

点选后会要你输入NM值，输入242或243即可(如果开启NetMonitor后想关闭，键入241便可)。

手机就会多出Net mo nitor（工程模式）了NOKIA工程模式详细介绍许多朋友都听说过工程模式，但对工程模式究竟如何开启又有哪些作用就不太清楚了，这里我以Nokia手机工程模式为例给大家介绍一下工程模式的开启和使用技巧。

几乎所有的Nokia手机都有工程模式，（经测试，Nokia的5110、5130、6110、6130、6138、6150、3210、8210、8850、6210、3310、8250均具备工程模式）不过它是隐藏在菜单中，需要特殊的方法打开工程模式后你才能看见。

Net Monitor在51××/6100中共有88个画面(如6100软件版本在V5.0以后则为89个画面)，6150则为89个画面，而8210则编号为140的画面，实际上有些为空，但总的比6150多。

前19个画面称为Operator Net Mo nitor，以系统网络功能为主；后面的则被称为R&D Net Monitor，以手机内软硬件的资料为主.注：诺基亚8210工程模式有140个画面注意:很多朋友都以为工程模式能修改手机功能或增强信号，其实，工程模式只能显示GSM900/1800网络的执行情形或显示手机内某些有用信息作为参考用，不能修改手机功能或增强手机信号，同时，由于手机本身并非精确的仪器，所有显示的数值仅是近似值，而且因为现在的网络技术不断更新，而手机软件是原先设计的，可能也会有不符的情况发生，因此切记，工程模式仅能作参考使用。

首先你的手机卡里至少要存33个电话号码,手机锁频就锁第33个电话号码,修改第33项的内容,也就是你想要锁的信道,然后进入你的手机测试程序第17项,当手机上显示
BTS TEST
REQUESTED
CH:你要锁的信道号,时
关机,开机,然后进入第17项
手机上显示
BTS TEST
ON
CH:你要锁的信道号
这时锁频成功,进11项便可看见CI及LAC了
中兴C705进入测试菜单的方法，不胜感激。

按*983*638#即可进入工程模式，
工程模式有个用处就是可以从第一行的S后面的数值可以看出是不是在本地和外地，这样拨打时就可以知道有没有漫游费了。

以后走到一个不认识的地方也可以从数值上看出是什么地方，呵呵，比较麻烦。

工程模式退出方法：按任意数字键，再按#键即可退出。

另外，按关机键约1.5秒也可以安全退出。
