FACTORY RESET
Performing a factory reset will clear all of your paired devices and can be used
as a troubleshooting method. Use the following steps to perform a factory reset:
a) Plug a charging cable into the Metro2
b) Press and hold the Volume Up “+” button until you see both the blue
and red LEDs turn on. There will be four long tones. The red LED will
remain on until the Metro is disconnected from the charger.
Note: The first time the Metro2 is turned on after the factory reset, it will enter
pairing mode automatically. If the Metro2 was previously paired with a device,
the pairing must be deleted from the device and the pairing process will need
to be repeated.
WARNING
Turn down the volume prior to using the headphones; adjust the volume to
the desired level once they are connected. Do not use headphones at high
volumes for extended periods of time as doing so will result in permanent
hearing damage. It is advised you keep volume levels moderate to low at all
times for your safety, even when loud background noise is present.
