由于摩托罗拉手机内含有测试程序,所以一张普通的测试卡(仅100多元)就能对所有摩托罗拉数字手机的工作状态进行控制,接受键盘输入的指令(有点类似于摩托罗拉模拟机自测试模式中的维修层次)。把测试卡使用得当,将会在维修中发挥很大作用。对于不上网的摩托罗拉系列数字机,可进入测试状态,用45×××#读取信道上的信号强度。若能立即读出,则说明接收基本上没有问题。用11×××#、12××#、31×#可以判断发射部分是否正常,若手机自动关机,则说明功放、功
Because Motorola phones contain testing procedures, an ordinary test card (just over $ 100) controls the working status of all Motorola digital handsets and accepts keyboard input commands (somewhat similar to the Motorola simulator self-test mode Maintenance level). Proper use of the test card, will play a significant role in the maintenance. Motorola does not go online series of digital machines, can enter the test state, with 45 × × × # read signal strength on the channel. If you can read out immediately, there is basically no problem receiving. With 11 × × × #, 12 × × #, 31 × # can determine the normal part of the launch, if the phone automatically shut down, then the amplifier, power
