B. Assigned Channel Scheme (preset system channel)
Both transmitter and receiver is assigned with a matching preset channel (channel
01~). Pitch & Catch, t-type, and multi-receiver configurations must set to
assigned channel scheme.
1) Rotate the power switch key to OFF ( 0 ) position.
2) With the STOP button elevated, press and hold PB1 and PB2
at the same time.
3) Rotate the power switch key to ON ( I ) position.
4) Let go PB1 and PB2 at the same time (entered Channel
Setting mode). The Status LED displays current channel
setting with red and green blinks. A green blink represents the
tens (+10) and a red blink represents the units (+1). For example, 1 green blink
followed by 5 red blinks is channel 15. Channel unassigned is represented by
constant orange on the Status LED.
5) Change transmitter channel by pressing PB1 to increment the units (+1) and PB2 to
increment the tens (+10). For example, press 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 rotate and hold the power
switch key at START position until the Status LED turns to constant green (transfer
complete). Turn off the transmitter power if constant 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 rotate 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 step 1~4 and step 6 to transfer the newly selected transmitter channel to
the receiver.
