Power On, Pairing and Power Off
To turn on or off the earphones you must follow this procedure:
Power On: Take out both earphones from the Power Bank.
Now both will blink blue and red, they will synchronize with each other, and enter in pairing
mode and we will hear beep in both earphones, and the LED will turn off.
If we have already synchronized them with the mobile, the earphones will connect directly
with the smartphone.
Pairing
The first time we use the device, we will have to pair it with our smartphone. This
procedure will have to be repeated every time you want to connect the earphones to a
new device. To turn on the headphones, we follow the procedure previously explained in the
manual. The earphones will flash blue and red and then connect to each other.
From your smartphone, look in the list of Bluetooth devices for the "Avenzo AV-TW5007" and
connect.
When the earphones are paired with your mobile, the LED will turn off and you will hear
"connected" in both earphones.
Once connected to your smartphone, you will not have to repeat the process again.
Power off: To turn off the earphones, insert them into the Power Bank. When they start
charging, the red and blue light will light on both.
