(1) Install the receiver antenna.
(2) Push the power buon to turn

the power on

(3)To turn o: push and hold the power

buon till the display shows

“Power O.”

(1) Push the REMOSET buon and the blue indicator starts to ash, indicating the receiver

is transmiing data (Figure 1).

*When using the REMOSET function of UF-20R, it is recommended to carry out RE-

MOSET one by one. is is to prevent the interference between the REMOSET signals
and the failure of data transmiing.

(2) REMOSET successful: the blue indicator on the transmier is on for 3 seconds and that

on the receiver stops ashing.

(3)REMOSET failed: Check the following when the blue indicator on the receiver ashes in

a slow pace:

1)If the receiver and the transmier are of the same frequency band.

2)e “Remoset Function” on in the function menu of Transmier is “activated;”

3)e “Device ID” is the same on both the receiver and transmier.

4)e transmier baery is low (synchronization is not possible if it is too low).

Notes:

(1)For receiver seings, please see: “6. Device ID” and “7. Microphone Seing” of 6-1
