IMPORTANT
READ THIS INSTRUCTION MANUAL CARE-
FULLY before attempting to operate the transceiver.
SAVE THIS INSTRUCTION MANUAL. This
instruction manual contains important safety and operating
instructions for the IC-A200.
FOREWORD
Thank you for purchasing the IC-A200 VHF AIR BAND
TRANSCEIVER with lcom’s state-of-the-art technology.
The IC-A200 can be installed in your instrument panel and
is easy to operate.
To fully appreciate the capabilities of your IC-A200, please
read this instruction manual thoroughly before attempting
operation.
If you have any questions regarding the operation of the
IC-A200, feel free to contact your nearest authorized lcom
Avionics Dealer or Service Center.
CAUTIONS
NEVER connect the transceiver to an AC outlet or to a
power source of more than 16 V DC. Higher voltage ruins
the transceiver.
NEVER connect the transceiver to a power source using
reverse polarity. This connection ruins the transceiver.
AVOID using or placing the transceiver in areas with
temperatures below — 20°C or above + 50°C.
DO NOT turn the power ON until the aircraft engines
have been started. This is important for protection of the
circuit.
EXPLICIT DEFINITIONS
Personal iniury, fire hazard or electric shock
CAUTION Equipment damage may occur.
NOTE If ignored, inconvenience only. No personal
injury or risk of electric shock.

—§
I Frequency selection I STBY window frequency
methods
There are 2 ways to select a desired frequency.
General frequency selection
Select a desired frequency which is used for the next
operating frequency in the STBY window. Then, ex-
change the USE window frequency for the STBY window
frequency.
Refer to STBY window frequency selection at right and
frequency exchanging. (p. 4)
Direct frequency selection
Select a desired frequency in the USE window directly.
Refer to USE window frequency selection. (p. 4)
selection
CAUTION: DO NOT turn the power ON until the
aircraft engines have been started. This is important for
protection of the circuits.
‘CONVENIENT: For quick frequency selection, often-
used frequencies can be programmed into memory
channels. Refer to memory operation. (pgs. 7~10)
When a memoiy channel is recalled, the previous STBY
window frequency is erased.
1) Rotate the volume control clockwise to turn the power
ON.
v Previously used frequencies appear in the USE and
STBY windows.
2) Rotate the large and small tuning knobs to select a
desired frequency.
0 The USE window frequency is not affected.
~To change the 1 MHz digit, use the large tuning
knob. The small tuning knob does not change the
1 MHz digit.

NOTE: To prevent interference, listen on the frequency
before transmitting. If the frequency is busy, wait until the
frequency is clear.
CONVENIENT: The intercom function is useful for
swift communication between the pilot and co-pilot.
Set the communication/intercom switch on the VHF
control panel to the “intercom” position. Voice signals
from the microphone are sent to both the pilot and
co-pilot’s headsets.
1) Select the yoke-mounted communication/intercom
switch to the "communication" position.
2) Select an operating frequency.
3) Push the PTT switch.

4 MEMORY OPERATION
I Programming notes
Blank channel
A memory channel with no frequency content is called a
blank channel. When a blank channel is selected while
programming, “ — - — —— ” appears instead of a frequency.
Switch operation
Note that “push” and “push and hold” performs different
functions at right.
The yoke-mounted channel switch cannot be used for
memory channel programming.
During memory channel programming, if no operation is
performed for approx. 15 sec., the transceiver automatically
operates as following:
—Writes the selected frequency into the selected memory
channel.
— Returns to normal operation.
Protect channel
To prevent accidental changes, required memory channels
can be specified as protected channels. Even if [I-->1 is
pushed and held, the frequency content does not blink and
it cannot be changed. Your lcom Avionics Dealer can
activate and cancel this setting.
I Programming a memory
channel
The transceiver is equipped with 9 memory channels. You
can program often-used frequencies into them.
1) Push and hold [CH] until the memory channel number
blinks.
2) Rotate the large or small tuning knob to select a
memory channel to be programmed.
3) Push [4-—>].
v Frequency content or “ — — — — ” blinks.
4) Rotate the large and small tuning knobs to select a
desired frequency.
5) Push [CH] to return to normal operation.
NOTE! To program other memory channels
successively push [4-0] after step 4) and repeat steps
2)~4).
To program a memory channel as a blank channel, select
“ — — — - .” Using the large tuning knob, “ — - — — "
appears between 118 MHz and 136 MHz.
