4. Frequency Dial S itch
4.1 Using ONE set of devices under the same environment
Usin the packa e provided flat screwdriver to dial the frequency switch of both transmitter and receiver to the
same channel (in the same channel number), the default channel number is “0”:
S-4915T S-4915R
4.2 Using TWO sets of devices under the same environment
It is su ested that set the dial switch of the first set to channel”0” and the second set to channel “5” :
S-4915T #1 S-4915R #1 S-4915T #2 S-4915R #2
