What should I do if the voice of the landline receiver is low?

1, first look at the wiring. If there is no sound, it can't be adjusted. The speaker in the microphone is affected with moisture, which reduces the sensitivity. The crystal plug from the microphone to the landline is oxidized, and the contact resistance is high.

2. The receiver in the handle is broken, usually the coil is moldy. You can know whether there is a cough by measuring both ends of the receiver with a low-resistance multimeter. The wiring of the handle is easy to be disconnected internally after long-term use. At this time, there should be noise when the hook is removed and the wiring is twisted.

3. The components in the receiving circuit are damaged, such as the capacitance leakage of the peripheral components of the call IC circuit such as TEA 1062, and the breakdown of the voltage regulator for power protection. This kind of fault is easier to deal with than the problem of line or telephone. You can take the phone somewhere else and try to determine what the problem is. If the line problem is reported for fault maintenance, you can only find a telephone maintenance point to repair the telephone problem. There are many problems in general receivers.
