1, change a larger charging head and data cable to try, no longer open to see if the battery can be removed, carefully separate, stop for a few minutes and then install. Wireless microphone and receiver can adjust the frequency, generally adjust the receiver is easier, the transmission of the microphone and receiver receiver frequency adjustment.
2. RTC: real-time clock control. RX: Receive. RXACQ: Receive a transmission request signal. RXEN: Receive enable (enable). In the standby state of the phone (that is, the phone is turned on, but no call is made), the signal is a pulse message that complies with TDMA rulesnumber If the logic circuit does not have this signal output, the mobile phone receiver cannot work normally. RXI/Q: Receives demodulation signals. In the standby state, the oscilloscope can also measure this signal, if the phone does not have this signal, the phone can not surf the Internet. 3, the theory is explained as follows: three satellites are used to obtain longitude, latitude and altitude positioning data, more accurate positioning requires a fourth satellite, the fourth satellite is used to calculate the time difference between the GPS satellite signal transmission and reception. Because the accuracy of the real-time clock (RTC) in the GPS receiver is much lower than the accuracy of the clock on the GPS satellite.
4, the engineering mode is used by engineers for testing, it is best not to move the Settings in the engineering mode, so as not to cause abnormalities in the mobile phone, if the mobile phone is abnormal in use, you can carry the mobile phone to the vivo customer service center for free testing, enter the vivo official website /vivo mall APP-- my -- network query, Select your current city to get the address and contact details of the customer Service center.
Yes! The battery may be damaged, or the charging port and charge management circuit may be damaged. It all needs to be checked to be sure.
Check whether the charger or the charging port is loose, or replace the charging cable to try. Then there is the battery failure in the microphone, if possible, replace the battery inside the microphone to try. If that doesn't work, you can only go to the special repair shop inspection.
The battery is broken, use a multimeter to measure the battery voltage, should be less than 1V. The voltage is smaller, which is fine for things like remote controls, wireless microphonesI won't be able to carry it.
Wireless Mike battery can be charged, mainly depends on whether the battery you choose is a rechargeable battery. Ordinary disposable batteries can't be recharged, the rechargeable ones are fine.
This situation is obviously the aging of Mai Li's battery, can not store electricity. The only way to do that is to replace the battery.
Method: Look at the battery. Check the receiving section. Set the microphone volume control knob separately. The above are normal, indicatingOne microphone is broken. The wireless microphone is composed of a pocket transmitter (which can be packed in a pocket with an output power of about 0.01W) and a centralized receiver.
Finally, if the above methods can not solve the problem, then there may be a more serious failure of the wireless microphone hardware. At this time, it is recommended to send the microphone to a professional repair shop for inspection and repair. Professional maintenance personnel can conduct a more in-depth inspection of the microphone to find and repair the root cause of the failure. In short, the repair method of a broken wireless microphone varies according to the cause of the failure.
The microphone may be broken and the battery is in poor contactThe battery can be reassembled and reinstalled. babycare children's wireless microphone is broken, it may be the microphone is falling apart, the microphone is a button structure, can be directly disassembled. Sometimes the microphone falls apart during use. It may also be that the battery is in poor contact, and the battery inside the wireless microphone often appears loose, resulting in a poor battery connection and a microphone that cannot work.
How to repair the wireless microphone is broken Wireless microphone repair method: open the switch to check whether the microphone is falling apart. The microphone is a button structure, can be directly disassembled. Sometimes the microphone falls apart during use. When the microphone falls apart, you can simply assemble the microphone in its original shape. The battery is in poor contact. The battery inside the wireless microphone often appears loose, resulting in a poor battery connection and the microphone cannot work.
Wireless microphone wrong high v battery broken can be repaired. The wrong high v on the wireless microphone can cause the motherboard to short circuit or even the main version to be broken down. It can be repaired only by replacing the motherboard. Unscrew the bottom of the wireless microphone. Pull out the battery port and twist out the radio port. Roll out the motherboard and replace it with a new motherboard. The microphone can be repaired.
Whether you will encounter thisThe situation: The wireless microphone (wireless microphone) transmitter is damaged accidentally during the use of the wireless microphone (wireless microphone). It doesn't matter if the equipment is cheap, just buy a new one. However, if it is very expensive and needs to be purchased again, it will cost a lot. Will you consider whether this thing can be repaired and whether it can be matched with the corresponding accessories like other equipment?
