Appendix B : Reset Button and Factory Defaults
The Reset Button has 2 functions :
1) To restore various internal settings to their factory default,
2) To force the unit into ‘bootloader’ mode ready for a firmware update.
Function 1 – Restore Factory Defaults
There are 2 levels to this function.
Level 1: With the unit already ON, press and hold in the reset button.
After approximately 5 seconds, and depending on the type of unit, either the
‘Power’ led will start to flash slowly (approx 3 per second) or the ‘Level-1 Reset’
message will be displayed. Releasing the reset button at this point will activate
Level 1, and then reset the unit.

Level 2 : With the unit already ON, press and hold in the reset button.
After approximately 5 seconds, and depending on the type of unit, either the
‘Power’ led will start to flash slowly (approx 3 per second) or the ‘Level-1 Reset’
message will be displayed. Continue to hold in the reset button until either the
‘Power’ led starts to flash rapidly (approx 10 per second), or the ‘Level-2 Reset’
message is displayed. Releasing the reset button at this point will activate Level 2,
and then reset the unit.
