SW2 can be used to Reset to Factory Default by changing the Rotary Switch
(SW3) to ‘D’ and pressing SW2.
To Clear Memory and Reboot the Unit:
1. Set rotary SW3 to D.
2. Press and release switch SW2.
Instructions appear on the LCD in approximately ten seconds.
3. Follow the instructions.
4. Set rotary SW3 back to 0 or F.
5. Press and release SW2, and observe the LCD panel. The unit will reboot,
the memory will be cleared, and the unit will need to be completely re-
configured.
In addition to clearing memory, SW2 can be used to restart the Linux operating
system and possibly clear up an error or hang situation. Software House
recommends contacting Technical Support before executing a factory reset.
