Warning !!!
Restoring the Factory Default Settings will DELETE all configuration information of the device.
Please backup or print out all the settings before attempting the following steps.
Please disconnect the network cable and power cycle the unit, before trying to reset the unit to the factory defaults.
The steps are as follows:
 Step 1: Find the MAC Address of the device. The MAC address of the device is located at the
bottom of the device. It is a 12 digits hex’ number.

Encode
the “MAC address to decimal” digits. Please use the following mapping:
0-9: 0-9

For example, for the MAC address: 00 0b 82 00 e3 95,
the User encoding should be : “00 0222 82 00 333 3 95”
 Step 3: Access the voice menu by pressing *** or the LED button, then dial “99” and get the voice
