RESTORE FACTORY DEFAULT SETTINGS

Warning:
Restoring the Factory Default Settings will delete all configuration information on the phone. Please
backup or print all the settings before you restore to the factory default settings. Grandstream is not
responsible for restoring lost parameters and cannot connect your device to your VoIP service provider.
Please follow the instructions below to reset the phone:
Pick up the handset, press *** to access the IVR menu. Enter 99 for factory reset. Then enter the MAC
address printed on the bottom of the sticker. Please use the following mapping:
0-9: 0-9
A: 22 (press the "2" key twice, "A" will show on the LCD)
B: 222
C: 2222
D: 33 (press the "3" key twice, "D" will show on the LCD)
E: 333
F: 3333
Example: if the MAC address is 000b8200e395, it should be key in as "0002228200333395".
Note:
•
If there are digits like "22" in the MAC, you need to wait for 4 seconds to continue to key in another "2";
•
Once the MAC address is correctly input, the phone will reboot. Otherwise, it will announce "Invalid
Entry" and exit to the main menu.
