What about cordless phones?
If cordless phones are not available for long periods of time, they should unplug the battery and remove the battery from the mobile phone. Otherwise, the mobile phone does not use for a long time, it is easy to make the battery discharge too much, so that the battery is not charged.
When the mobile phone is not charged, it always shows the "low power" state. One of the reasons is that the battery is discharged too far after the power is dropped to a certain value, so that the circuit can not be charged. After two years of using the battery, when the power supply is enough, the time is not long. The battery is dead and the battery needs to be replaced.
Mobile phone and landline call process, if the phone is too far away from the landline or too much interference, and interrupt communication, you need to close the plane shutdown. If the plane has automatic shutdown, you need to phone the battery reset, re code, you can use. In the case of greater interference, some models can continue to communicate by pressing the "channel" key to change the channel and continue to interrupt the signal.
When using a wireless mobile phone call, encountered noise should pay attention to: (1) when the wireless mobile phone call big noise, you can press the "channel" mobile phone keys, skip the current communication channel, the system automatically choose a free communication channel. (2) extend the antenna of mobile phone and plane. (3) the location of the plane determines the phone's calling distance. Planes should be kept away from interference sources (computers, fax machines, television sets, etc.). The proximity of mobile phones and planes affects the quality of calls. To improve the quality of calls, the aircraft should avoid interference and shielding.
1., when buying a cordless telephone, it should be installed according to the instruction manual. The cell phone is charged on the charging seat and charged enough for a long time to use the code. This should be the case with a new battery. 2. in cordless telephones, the communication between a landline and a cell phone is carried out by radio waves, and most household appliances interfere with the airwaves. As a result, cordless telephones should be installed away from televisions and microcomputers. The AC power supply of a cordless telephone can not share a power outlet with an electric motor product, such as a refrigerator, a washing machine, an air conditioner, and a microwave oven.
