REVERSE FUNCTION
The reverse function exchanges a separate receive
and transmit frequency. So, while using a repeater,
you can manually check the strength of a signal that
you receive directly from the other station. If the
station’s signal is strong, both stations should move
to a simplex frequency and free up the repeater.

AUTOMATIC SIMPLEX CHECK (ASC)
While using a repeater, the ASC function periodically
checks the strength of a signal that you are receiving
directly from the other station. If the station’s signal is
strong enough to allow direct contact without a
repeater, “

TONE FREQ. ID SCAN
This function scans through all tone frequencies to
identify the incoming tone frequency on a received
signal. You may use the function to find which tone
frequency is required by accessing your local
repeater.
