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
