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 Icom’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 ‘ead this instruction manual thoroughly before attempting ‘operation. |W you have any questions regarding the operation of the 1C-A200, feel free to contact your nearest authorized Icom ‘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 tum the power ON unt the aircratt engines have been started. This is important for protection of the ircuit. EXPLICIT DEFINITIONS [cea dare al or It ignored, inconvenience only.

Ask your Icom Avionics Dealer for wiring Headphone jack Connects a 500 2 headset. Microphone audio jack Connects a low-impedance carbon or dynamic microphone. ‘A preamplifier is required for a dynamic microphone.

General frequency selection Select a desired frequency which is used for the next ‘operating trequency 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 directy Refer to USE window frequency selection. (p. 4) CONVENIENT: For quick frequency selection, often- used frequencies can be programmed into memory ‘channels. Refer to memory operation. (pgs. 7~10) When a memory channel is recalled, the previous STBY window frequency is erased. FREQUENCY SELECTION I STBY window frequency selection CAUTION: DO NOT turn the power ON until the, aircraft engines have been started. This is important for protection of the circuits, 1) Rotate the volume control clockwise to tum the power ON. ‘© Previously used frequencies appear in the USE and STBY windows. 2) Rotate the large and small tuning knobs to select a desired frequency. ‘+ The USE window frequency is not affected. ‘*To change the 1 MHz digit, use the large tuning knob. The smail tuning knob does not change the 1 MHz digit. = 150 KHz stops when pushed INli Frequency exchanging After selecting the STBY window frequency, push [=] to exchange the USE window frequency for the STBY window frequency. Frequency exchanging can also be performed remotely trom the yoke-mounted frequency exchange switch.

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 [==] is pushed and held, the frequency content does not biink and it cannot be changed. Your Icom Avionics Dealer can activate and cancel this setting. li 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 [ep]. ‘* 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.
