Tips:
1. Do not remove or replace the built-in lithium battery
2. The power adapter and the main unit have a certain amount of heat during the charging process, which is normal.
3. Charge for at least 4 hours for the first time, and then use it out completely. After three consecutive times, the battery can be used optimally.
Bluetooth Open Method:
After booting, press and hold the M button for about 3 seconds to hear a very clear sound, then the indicator light is blue that means the Bluetooth function is turned on.
Bluetooth Connection Method:
Turn on the Bluetooth function of the mobile phone, enter the Bluetooth search interface of the mobile phone system (or another smart device with Bluetooth function), find the name of the Bluetooth device of ZTQ and click the connection. After the connection is successful, there will be a voice prompt for the successful pairing of "Pairing successfully".
Note: When the battery is low, the Bluetooth function will not be used, but the sound amplifier can work normally, because the power consumption of the sound amplifier is smaller, so please charge it when the Bluetooth function is not used.
Bluetooth usage:
1. When a call comes in, press the M button to answer or hang up, and press and hold for 2 seconds to disconnect.
2. When playing music, short press the M button to pause or resume playback.
3. If there is no sound signal for 10 seconds, the machine will automatically exit Bluetooth mode to enter the hearing aid mode and exit the Bluetooth connection after a period of time.
