FACTORY RESET
There are three (3) methods for resetting your unit:
Reset Button
Reset default factory settings following these four (4) steps:
1. Unplug the Ethernet cable.
2. Locate a needle-sized hole on the back panel of the HT–502 unit next to the power
connection.
3. Insert a pin in this hole, and press for about 7 seconds.
4. Take out the pin. Factory unit settings are restored.
MAC Address
Reset default factory settings by changing the MAC Address:
1. Locate the MAC address of the device. It is the 12 digit HEX number on the bottom of the
unit.
2. Key in the MAC address. Use the following mapping:
0-9: 0-9
a. A: 22 (press the “2” key twice, “A” will show on the LCD)
b. B: 222
c. C: 2222
d. D: 33 (press the “3” key twice, “D” will show on the LCD)
e. E:
333
f. F: 3333
For example : if the MAC address is 000 b 8200 e 395, it should be key in as “000 222 8200 333 395”.
NOTE: If there are digits like “22” in the MAC, you need to type “2” then press “->” right arrow key to
move the cursor or wait for 4 seconds to continue to key in another “2”.
