5. Change transmitter channel by pressing PB1 to increment the units (+1) and PB2 to
increment the tens (+10). For example, pressing PB2 two times and then PB1 four
times is channel 24 (Status LED blinks 2 greens and 4 reds).
6. Transfer the newly selected channel to the receiver by rotating and holding the power
switch key at START position until the Status LED turns to solid green (transfer
complete). Turn off the transmitter power if solid green is not shown on the Status LED
after more than 10 seconds (transfer incomplete); the transmitter will revert back to its
previous channel setting. Make sure the receiver power is turned on and within the
operating distance during the entire process.
Skip step 6 if changing receiver
channel is not required.
7. Exit Channel Setting mode by rotating the power switch key to OFF ( 0 ) position.
NOTE:
When selecting a new channel, make sure each button press does not
exceed 3 seconds.
Important Note:
Step 6 illustrated above is strictly required if you are intending to change the entire
system channel (both transmitter and receiver). The entire system no longer works if
step 6 is skipped because the transmitter and receiver channels are now different (new
vs. old). In this case you would have to redo steps 1-4 and step 6 to transfer the newly
selected transmitter channel to the receiver.
