Verify channel and frequency in use
The channel LED① will show last stored frequency and channel. For example, if channel 36 is
608.750MHz, the LED will first display 60,87,50 and 36 in sequence.
Select a channel that corresponds to the transmitter. When transmitter is turned on, either A or B
diversity indicator② will light up to indicate that it is connected.

CHANNEL scanning (IrDA series only)
For an interference- free operation, a cleaner channel might be necessary if the current one
receives too much interference. Before scanning, the transmitter must be switched off.

seconds

SQUELCH (SQ) setting
When interference is encountered try reducing the sensitivity of the receiver by
turning the SQ control clockwise, thus less susceptible to interference. If this still
does not solve the problem it means this frequency is not suitable. Adjust the
squelch back to where it was and use the scan function to locate a clear,
interference-free channel.
