Does wanji technology etc charge?

Wanji technology etc does not need to charge. It is known from the instruction manual of Wanji Technology etc that the two buttons of Wanji Technology etc are generally the power button and the Bluetooth on-off button, and different types of OBU devices are slightly different. If "tag failure" is displayed without electronic tag, it is a normal phenomenon and does not affect activation. You can also directly press the button at the top of the electronic tag to turn on the Bluetooth function.

Extended data:

Several cases of unsuccessful connection between 10,000-machine etc and mobile phone Bluetooth;

1. Bluetooth was not set to "visible to all" when it was turned on, or the Bluetooth turn-on time of 1 10,000 sets of etc devices (about 2 minutes) was exceeded, so the Bluetooth function needs to be turned on again.

2. Some Wanji etc devices may have a pairing password when connecting via Bluetooth. The initial password is 0000 or 1234. You can also check the pairing password in the instruction manual of Wanji etc.

3. If the Bluetooth connection exceeds the signal receiving distance (about 10 meter), obstacles, strong magnetism, signal towers, airports, etc. may interfere with the Bluetooth connection, please try the connection operation again away from these places.
