EXPLICIT DEFINITIONS

WORD DEFINITION

RWARNING

CAUTION

NOTE

Personal injury, ﬁre hazard or electric shock may occur.

Equipment damage may occur.

If disregarded, inconvenience only. No risk of personal injury, ﬁre or electric shock.

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 supplied microphone only. Other microphones have

different pin assignments and may damage the transceiver.

DO NOT use or place the transceiver in areas with tem-

peratures below –22°F (–30°C) or above +140°F (+60°C) or, in areas subject to direct sunlight, such as the dashboard.

AVOID operating the transceiver without running the vehi-

cle’s engine. The vehicle’s battery will quickly run out if the transceiver is in transmission while the vehicle’s engine OFF.

AVOID placing the transceiver in excessively dusty envi-

ronments.

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.
