Channel Change via Pushbuttons
Other than the CHANNEL dipswitch on the encoder board, the transmitter channel can
also be changed directly on the pushbuttons. Please refer to the instructions below on
how to change the transmitter channel via pushbuttons.
1. Press and hold PB1, PB2 and PB3 and rotate the power key to the START position at
the same time. A series of green and red blinks will appear on the Status LED, show-
ing the current channel setting. A green blink represents the tens (+10) and a red blink
represents the units (+1).
Examples:
2 green blinks followed by 5 red blinks represents channel 25.
6 red blinks represents channel 06.
2. Select a new channel by pressing PB1 and PB2 on the transmitter. Press PB1 to
increment the units (+1) and PB2 to increment the tens (+10).
Examples:
Pressing PB2 two times and then PB1 four times will give you channel 24.
Pressing PB1 nine times will give you channel 09.
