Changing Receiver Modes

2. Press and hold the

power

key for more than 8 seconds, but less than 14

seconds.

3. Release the

power

key when both LEDs become red. When the LEDs

turn off, your receiver will be in Zero Power Mode.

4. Press the

Reset

key for about one second to return to Normal mode.

Notice:

When the internal batteries have completely discharged
and no external power is connected, the receiver will go
into Zero Power Mode automatically to prevent the
batteries from over discharging.
