SAFETY TRAINING INFORMATION
Your Icom radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as Occupational Use Only, meaning it must be used only during the course of employment by individuals aware of the hazards, and the ways to minimize such hazards. This radio is W ARN ING NOT intended for use by the General Population in an uncontrolled environment. This radio has been evaluated for compliance at the distance of 2.5 cm with the FCC RF exposure limits for Occupational Use Only. In addition, your Icom radio complies with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for exposure to humans: FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields RF and Microwave. The following accessories are authorized for use with this product. Use of accessories other than those specied may result in RF exposure levels exceeding the FCC requirements for wireless RF exposure.; Belt Clip (MB86/103), Rechargeable Ni-MH Battery Pack (BP-210N) and Alkaline Battery Case (BP-208N). To ensure that your expose to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines: DO NOT operate the radio without a proper antenna attached, as this may damaged the radio and may also cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio by the manufacturer or antenna specically authorized by the manufacturer for use with this radio. DO NOT transmit for more than 50% of total radio use time (50% duty cycle). Transmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio is transmitting when appears on the function display. You can cause the radio to transmit by pressing the PTT switch. ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when transmitting and only use the Icom belt-clips which are listed on page 31 when attaching the radio to your belt, etc., to ensure FCC RF exposure compliance requirements are not exceeded. To provide the recipients of your transmission the best sound quality, hold the antenna at least 5 cm (2 inches) from your mouth, and slightly off to one side. The information listed above provides the user with the information needed to make him or her aware of RF exposure, and what to do to assure that this radio operates with the FCC RF exposure limits of this radio.
Electromagnetic Interference/Compatibility
During transmissions, your Icom radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals and blasting sites.
Occupational/Controlled Use
The radio transmitter is used in situations in which persons are exposed as consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure.

OPTIONAL HEADSET CONNECTION
D OPC-499 (HEADSET ADAPTER) connection
When using a headset, such as those from the David Clark Co. via the OPC-499 HEADSET ADAPTOR adapter, the transceiver outputs your transmitted voice to the headset for monitoring. See I Side tone function (p. 11) when setting the side tone level.

PTT switch

Use a PTT switch with a 3.5 mm (1/8") diameter plug, if required.

Icom A24 & A6 VHF Air Band Transceivers

RWTUV USA CERTIFIED

The IC-A24/A6 has a completely renewed style with a large LCD and speaker. It offers simple operation by way of a minimum of practical functions. With its stylish design and reliable performance, the IC-A24/ A6 series is a fitting successor to the award winning IC-A23/A5. FEATURES: Durable, stylish body New channel recall function Variety of battery packs and case (Compatible with Icom F series battery pack/case) Simultaneous operating and charging from external power source VOR navigation function (IC-A24 only) Dedicated 121.5MHz Emergency key (Programmed with 121.5MHz homing frequency) Water resistant, equivalent to IPXalphanumeric memory channels with memory banks Side Tone function ANL function DETAILS: Durable Stylish Body: The IC-A24/A6 design has incorporated the size and durability of the IC-A22/A3 and retains the basic user friendly interface users loved about the IC-A23/A5. The large LCD, large speaker and easy-to-use panel layout makes it a rank above the rest. On the side of the radio, it has a non-slip slit to prevent accidental dropping. Large Alphanumeric LCD: For the function display, a 6-character 14segment alphanumeric LCD is employed to make a variety of information visually recognizable immediately. An automatic LCD backlight is standard for night time operation. Channel recall function: New for the IC-A24/A6, this function automatically memorized the last 10 used channels. You can easily recall those channels by pushing the recall buttons on the front panel. It is very convenient for switching between several channels at a time, such as NAV channels and COM channels etc. Icom F Series Battery Packs & Case: The IC-A24/A6 shares the same battery packs and case with the popular land mobile radios IC-F11, F3G, F30G series. Variety of battery types, Ni-Cd, Ni-MH, Li-Ion are optionally selectable. The BP-208N, battery case is available with 6 AA (LR6) alkaline cells as a backup battery source. Simultaneous Operation & Charging From External Power Source: The IC-A24/A6 has an external DC power jack for operation with the AC adapter, BC-110, the optional lighter cable with DC-DC converter, CP20. When battery pack is installed to the radio, it is also simultaneously charged during operation. An external 11.0V DC power source is acceptable.

Dedicated 121.5MHz Emergency Key: A dedicated red emergency key programmed with a 121.5MHz homing frequency is equipped to give you extra confidence in the event of an emergency. VOR Navigation Function: The IC-A24 has VOR navigation functions. The DVOR mode shows the radial to (or from) a VOR station and the CDI mode shows the course deviation to (or from) a VOR station. You can also input your intended radial to (or from) a VOR station and show the course deviation on the display. In the USA version, the duplex operation allows you to call a COM channel such as a flight service station etc., while receiving a VOR station. Large 200 Memory Channel Capacity With Memory Banks: A total of 200 memory channels can be named with a 6-character channel name for easy recognition. By grouping these channels into 10 memory banks, quick and easy operation is possible. The optional PC cloning software, CS-A24 allows you quick and easy memory management from your PC. Water Resistant, Equivalent To IPX4: The water resistant construction provides reliable operation in wet conditions. Side Tone Function: The side tone function allows you to hear your own voice via a headset. By monitoring you own voice, this function eliminates unnecessary shouting on a noisy runway. Side tone level is adjustable from the transceiver. (Optional OPC-499 Headset Adapter Cable and external aviation headset are required.) Variety Of Scanning Functions: The COM band scan checks all of the busy COM band channels, and the memory scan checks the tagged memory channels. Weather channel scan is also possible. Other Functions: NOAA Weather Channels 5W (PEP) Output Power Low Battery Indication & Over Voltage Alert BNC Type Antenna Connector Keypad Backlighting ANL (Auto Noise Limiter) reduces noise components SPECIFICATIONS: GENERAL: Frequency Range: Transmit IC-A24/A6 Receive IC-A24 IC-A6 WX Channel Spacing Mode No. of Memory Channels Antenna Impedance
