VHF AIR BAND TRANSCEIVERTSO version

High-Quality Panel Mount Radiowith Clear Visibility OLED Screen
High Visibility OLED Screen

Large Switch Buttons

The OLED (Organic Light Emitting Diode) emits
light from itself,
so a display backlight is not required. It provides higher contrast, wider
viewing angle of almost 180 degrees and faster response time than a conventional LCD. The IC-A220’s
display has a wide active area, operating frequencies’ characters can be maximized in the display, while operating
status can be shown on both top and bottom of the display.

The IC-A220 has large switch buttons on the front panel. The
most frequently used FLIP-FLOP (Frequency exchange) switch
button is designed large enough to be pushed with ease. Allswitch buttons and knobs are illuminated with pure-white backlighting which are the same color as the OLED display.

TSO/ETSO Certification
The IC-A220 TSO version can be used as a primary VHF
radio in general aviation (part 23) aircraft*. The IC-A220 TSO
version is also accepted as an ETSO radio under the TSO/ETSO reciprocal acceptance policy.

VHF AIR BAND TRANSCEIVER

Auto Squelch Function

8.33 kHz Channel Spacing

The squelch sensitivity is automatically adjusted in accordance with the noise level toeliminate annoying background noise andunwanted signals.

The IC-A220 allows switching between
8.33 kHz and 25 kHz frequency steps in
the menu mode.

Quick Squelch Adjustment* Use of 8.33 kHz channel spacing may be prohibited depending on country.

The auto and manual squelch including
squelch level can be quickly accessed with
the Volume knob. The squelch test function
temporarily opens the squelch and allows
you to monitor signals.

Remote Control Capability

Auto Dimmer

As the TSO specifications require, theradio continues to work with the reduced
power supply voltage.

The auto dimmer function sets display andkey backlighting brightness. The IC-A220’s
high sensitivity light sensor covers a wide
illumination range.

External Dimmer Control
By connecting to an external dimmer control system on the aircraft, the IC-A220’s
dimmer function can be linked with theaircraft dimmer level. The external dimmer
control can be used on either 13.8 V or
27.5 V electrical systems.

Intercom Function
The IC-A220 has a built-in voice activatedintercom function allowing the pilot totalk with the copilot via the headset. The
IC-A220 has adjustable audio level andsquelch control functions.

Memory Channels
The IC-A220 has 20 memory channels and20 history memory channels respectively.
Often used memory channels can be instantly recalled. Group memory channels
are organized into 10 memory channels
by 5 groups (total 50 channels). Weather
channel scanning function searches forweather channel signals.

You can remotely control the FLIP-FLOP(frequency exchange), intercom and recall
switches via the rear panel connector.

9 V Power Supply Operation

Configuration Menu
To improve operability, menu items are divided into two modes, a settings menu anda configuration menu. Seldom-changed
settings can be set in the configuration
menu, while normal settings can be madein the settings menu.
