4.1.2
Transmitter Channel Settings
A.
Unassigned Channel Scheme (no preset system channel)
When both transmitter and receiver are set to unassigned channel scheme (no
preset channel), the system automatically searches and locks onto a free and
uninterrupted channel at every transmitter startup.
NOTE:
Pitch and catch, tandem, and receiver select configurations are unable to be
set to the unassigned 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. Release PB1 and PB2 at the same time. The system will enter
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 solid orange on the Status LED.
5. Change transmitter channel to “channel unassigned” by pressing PB4 one time
(Status LED displays solid orange).
6. Transfer “channel unassigned” setting 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 the receiver
is within the operating distance during the entire process. When transmitter is set to
“channel unassigned” the receiver must also set to “channel unassigned” in order for
the entire system to work.
7. Exit Channel Setting mode by rotating the power switch key to OFF ( 0 ) position.
