WARNING: Restoring the Factory Default Setting will delete all configuration information of the phone.
Please backup or print all the settings before you restoring factory default settings. Grandstream is not
responsible for restoring lost parameters and cannot connect to your VoIP service provider.
Directions for Restoration:
Disconnect network cable and power cycle the unit before resetting factory default settings.
1. Step 1: Find the MAC address of the device. It is a 12 digits HEX number located on the bottom
of the unit.
2. Step 2: Key in the MAC address printed on the bottom of the sticker. Please use the following
mapping:
