AUTOMATIC REPEATER OFFSET
This function automatically selects an offset direction,
according to the frequency that you select on the
144 MHz band. The transceiver is programmed for
offset directions as shown below. To obtain an up-to-
date band plan for repeater offset direction, contact
your national Amateur Radio association.

REVERSE FUNCTION
After programming an offset on the 29, 50, 144, 430
(440) MHz, and 1.2 GHz (Optional) band, 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 to free up the repeater.

AUTOMATIC SIMPLEX CHECK (ASC)
ASC functions only when you have programmed an
offset on the 29, 50, 144, 430 (440) MHz or 1.2 GHz

periodically monitors the strength of a signal that you

signal is strong enough to allow direct contact without
a repeater, the ASC indicator on the display starts
blinking.
