VHF AIR BAND TRANSCEIVER

IC-A4

Maximize your ground crew communications

Rugged construction
The one piece, die-cast aluminum chassis and polycarbonate front panel provide the durability needed for reliable operation under the most demanding conditions.

Simple operation
Reliable communication is essential in the hectic airport work environment. The IC-A4's large display is easy to read and shows operating status at a glance. Up/down keys allow you to change channels quickly and easily. Up to 19 memory channels can be programmed for easy recall.

PC programmable
PC programming and cloning allows you to customize each radio to your needs. Transmit can be inhibited by channel. (These features must be activated by your dealer.)

Alpha memory
The channel name function allows you to assign up to 5-character alpha names to each channel. This provides a convenient way to remember channel contents and to recognize selected channels at a glance.

Compact body
Measuring only 58(W) × 140.5(H) × 32.3(D) mm*, the IC-A4 is truly portable. Small enough to fit into a pocket.
* 2 9/32(W) × 5 17/32(H) × 1 9/32(D) in

Other features

	LCD backlighting allows you to read the display easily during nighttime operation
	Maintenance-free EEPROM stores memory channel information
	Side-tone permits hearing your own transmitted audio while using a standard aviation headset (optional headset adapter required ^__ OPC-752)
	Standard headset cable can be used with the optional OPC-752
	Optional longer life 1050 mAh battery available, same physical size!!
	Optional (AA) alkaline battery case available ^__ holds 8 batteries
