PRECAUTION
RWARNING! NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electric shock.
NEVER connect the transceiver to a power source of more than 16 V DC such as a 24 V battery. This connection will ruin the transceiver.
NEVER cut the DC power cable between the DC plug and fuse holder. If an incorrect connection is made after cutting, the transceiver might be damaged.
NEVER place the transceiver where normal operation of the vehicle may be hindered or where it could cause bodily injury.
NEVER allow children to touch the transceiver.
NEVER expose the transceiver to rain, snow or any liquids.
USE the specified microphone only. Other microphones have different pin assignments and may damage the transceiver.
DO NOT use or place the transceiver in areas with temperatures below –30°C (–22°F) or above +60°C (+140°F), or in areas subject to direct sunlight, such as the dashboard.
i
AVOID operating the transceiver without running the vehicle’s engine. The vehicle’s battery will quickly run out if the transceiver transmits while the vehicle’s engine OFF.
AVOID placing the transceiver in excessively dusty environments.
AVOID placing the transceiver against walls. This will obstruct heat dissipation.
AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they damage the transceiver surfaces.
BE CAREFUL! The transceiver will become hot when operating continuously for long periods.
For U.S.A. only
CAUTION: Changes or modifications to this transceiver, not expressly approved by Icom Inc., could void your authority to operate this transceiver under FCC regulations.
