4 Function Settings
4.1 Transmitter
4.1.1 Transmitter Firmware Version
1. Press down the STOP button (transmitter power off).
2. Press and hold PB1 and PB3 at the same time.
3. Reset the STOP button by rotating it clockwise or counter-
clockwise; it will pop up (transmitter power on).
4. Release PB1 and PB3 at the same time. The Status LED will
display the firmware version with red, green and orange blinks.
5. Exit Firmware Version mode by pressing down the STOP button
(transmitter power off).
4.1.2 Transmitter Channel Settings
1. Press down the STOP button (transmitter power off).
2. Press and hold PB1 and PB2 at the same time.
3. Reset the STOP button by rotating it clockwise or counter-
clockwise; it will pop up (transmitter power on).
4. Release PB1 and PB2 at the same time. 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.
5. Change the 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 pressing and holding the START
button until the Status LED turns to constant green (transfer complete). Press down the
STOP button 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 the receiver channel is not required.
7. Exit Channel Setting mode by pressing down the STOP button (transmitter power off).
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 intend 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 through 4 and step 6 to transfer the newly selected transmitter channel to the
receiver.
