手柄音量开关失灵或卡住
音量开关可能卡在某个音量位置，或者无法正常工作
电话线未正确连接
作为预防措施，请确保电话线已正确连接。
开关卡在某一音量档位
检查开关并确保其外部连接正常。如果正常，则可能是内部布线问题，或者模块本身工作异常。
内部布线未连接好或内部模块损坏
你需要拆开手机检查内部布线，问题不在开关本身。
挂断按钮无法挂断
用于挂断电话的按钮无法正常工作。
杂物可能导致按钮卡住
检查是否有杂物卡住并导致开关被按下。如果没有，你可能需要拆开手机检查挂断按钮开关。
连接到按钮的电线可能已断开
这种情况下，请重新连接线路。
挂断按钮位于手柄内部，键盘上方。你需要拆开手机并检查连接到开关的布线。如果有任何松动或断裂的电线，这可能是问题的原因。如果布线看起来完好，则需要检查按钮内的弹簧机构，或者需要更换按钮本身。
键盘无法拨号、无功能或不亮
键盘无法拨号、无法正常亮起或完全无法工作。
电话线未正确插入
在检查其他故障现象之前，请检查并确认电话线已正确插入。
LED 损坏
如果键盘可以使用但 LED 不亮，则可能需要更换内部的 LED/光源。
液体胶水可能渗入键盘或键盘中有杂物
如果键盘无法正常工作，你可能需要拆开手机从内部检查键盘，查看是否有液体胶水渗入或杂物卡在里面。
可能需要重新安装塑料键盘。通过拉出主电路板并脱开按键电路板，可以将按键电路板拆解。大部分按键电路板本身由粘性胶水粘合。首先拆下装饰盖板，然后是实际的数字按钮板。当键盘从数字按钮板上拆下后，即可进行更换。
扬声器不工作或听不清楚
扬声器无法正常工作，或者你这边听起来很费劲。
电线可能已断开
这种情况下，请重新连接电线。
扬声器听不清楚
确保问题不是出在你这一端，请使用多个通话对象进行测试。
如果问题依然存在，你需要拆开手机进行进一步调查。可能需要更换扬声器。
扬声器位于手柄内。拆开手机。首先检查可能连接到开关的布线，如果有任何松动或断裂的电线，这可能是问题的原因。如果布线看起来完好，则应安装一个新的扬声器。

Key pad doesn't light up everything else works fine. Completely new phone
mdeliz38 - 回复 分享
I just bought one of these AT&T Trimline phones and it is backlit only on the diagonal. That means the outer portions of the keypad are dim (almost dark). Is this normal? The version of this same phone in the past had keys that were lit across the entire keypad evenly. My brand-new phone looks like the keypad is half lit, half not. I suspect that they reduced the number of LEDs and that this is now *normal* as opposed to a defect. Would I be correct that the newer AT&T Trimline phones are not lit as well as they were in years past due to a design change on the part of the manufacturer — or did I in fact get a defective phone?

I just bought one of these slimline telephones because the last one was defective. Now, this phone does not work either, nor does it light up. I understand that prison labor, or slave labor is involved, so it does not surprise me that these telephones are defective. I am receiving a replacement within the next few days, and if that one does not work, they will refund me. Then I will need to get to a store to find a phone that works, because I need my landline telephone. Nothing is properly made anymore. Everything is cheap, plastic disposable crap. Nobody takes any pride in anything anymore. Miss the good old days. Even the food, and water is toxic garbage.

This is my second Slim Line phone by AT an T and Verizon tech just verified phone does not work. The tab that hangs the phone up does not stay up (wall mounted). I am returning the phone, but will pick another brand. I live in the boonies, so need to have a land line as Verizon Wireless can be sketchy. Tremendous disappointment.
