NVRAM clearing with MinPad

NVRAM clearing with MinPad

It is possible to clear NVRAM using only MinPad. To do that: 

• Turn the receiver OFF. 

• Press and hold FN button. 

• Press and release PWR button to turn the receiver ON. 

• Wait until both LEDs will light green. 

• Wait around five seconds, until both LEDs will blink orange. 

• Release FN button. 

Note that LEDs will blink orange only during next five seconds, and to clear 
NVRAM it is essential to release FN button when they blink yellow.
