•	AFC FUNCTION	The need to consider frequency drift is over
with the IC-1200A/E

since the transceiver incorporates ICOM's AFC (Automatic
Frequency Control) function. AFC automatically and
conveniently adjusts the frequency the IC-1200A/E receives
to the frequency of the transmitting station.

•	COMPACT AND HIGH	Smaller and more compact than many
conventional automobile OUTPUT POWER transceivers, the
IC-1200A/E still provides 10W of powerful output

on any frequency in the 1200MHz band.

•	SIMPLE PANEL DESIGN	Even with so many sophisticated
functions available, the transceiver

front panel layout is extremely simple, making the
IC-1200A/E a mobile unit that is both versatile in
performance and safe to use while driving.

•AUTOMATIC DIMMER	A built-in light sensor automatically
adjusts a dimmer circuit to

CIRCUIT	control the backlighting of the LCD READOUT. This
feature is

convenient for reducing eye fatigue during night operation.

•	21 MEMORY CHANNELS	The IC-1200A/E introduces a large
capacity memory with 21 fully

programmable memory channels, placing a variety of
communications functions at the fingertips of the driver.

•	DUAL SCANNING	• FREQUENCY SCAN:

FUNCTIONS	Searches the entire band continuously with
frequency increments

specified by the operator.

•	MEMORY SCAN:

Continuously checks all memory channels.

•SUBAUDIBLE TONE	The IC-1200A/E incorporates 38 different
subaudible tones, ensur-

ENCODER	ing maximum communications coverage by allowing full
access to

all local repeaters.

•SQUELCH OPTIONS	The UT-28 and UT-29 are two new optional
units specially designed

for the IC-1200A/E and are ideal for handling the crowded
band conditions found in many locations.

•	UT-28 DIGITAL CODE SQUELCH UNIT:

The UT-28 incorportates a system of digital coding and
decoding, that allows a “personalized” squelch to be
programmed using 1 of 100,000 different code numbers.

•	UT-29 TONE SQUELCH UNIT:

The UT-29 is a subaudible tone encoder/decoder that can be
installed as an alternative to the UT-28 Digital Code
Squelch Unit.
