Restore Factory Default Setting

WARNING! Restoring the Factory Default Setting will DELETE all configuration information of the phone. Please BACKUP or PRINT out all the settings before you approach to following steps. Grandstream will not take any responsibility if you lose all the parameters of setting and cannot connect to your VoIP service provider.

There are two ways to reset the device.

RESET VIA THE RESET BUTTON

1.Locate a needle-sized hole on the back panel of the HT–502 unit next to the power connection.

2.Insert a pin in this hole, and press for about 7 seconds. The back LEDs for LAN and WAN will be solid on to indicate the reset.

3.Take out the pin. All unit settings are restored to factory settings.

RESET VIA IVR

1.Find the MAC address of the device. It is a 12 digits HEX number located on the bottom of the unit.

2.Encode the MAC address. Please use the following mapping:

0-9: 0-9

A:22

B:222

C:2222

D:33

E:333

F:3333

For example, if the MAC address is 000b8200e395, it should be encoded as “0002228200333395”.

3.To perform factory reset:

-Pick up the headset and dial “***” for voice prompt.

-Enter “99” and get the voice prompt “Reset”.

-Enter the encoded MAC address of the device.

-Wait for 15 seconds. The device will reboot automatically and restore to factory default setting.

NOTE:

1.Factory Reset will be disabled if the “Lock keypad update” is set to “Yes”.

2.Please be aware by default the HT-502 WAN side HTTP access is disabled. After a factory reset, the device’s web configuration page can be accessed only from its LAN port.
