EXPLICIT DEFINITIONS
WORD DEFINITION
R WARNING!
CAUTION Equipment damage may occur.
NOTE
Personal injury, re hazard or electric
shock may occur.
If disregarded, inconvenience only. No
risk of personal injury, re or electric
shock.
ANTENNA
A key element in the performance of any communication
systems is the antenna. Contact your dealer for
information regarding antennas and how to install them.
FUSE REPLACEMENT
Fuses are installed in the supplied DC power cable*. If a
fuse blows, track down the source of the problem, repair it,
and then replace the damaged fuse with a new rated one.
*Depending on version, only 1 fuse holder may be attached.
L Fuse rating: 250 V 10 A (for 1 fuse holder)/
NOTE: Use only specied fuses.
Fuse Coding Explanation
Fuse Coding: FUSE 250 V 10 A
Fuse Voltage Rating: 250 Volts
Fuse Current Rating: 10 Amperes
20 A (for 2 fuse holders)
CLEANING
If the transceiver becomes dusty or dirty, wipe it clean with
a soft, dry cloth.
PRECAUTIONS
R WARNING! NEVER connect the transceiver to an AC
outlet. This may pose a re hazard or result in an electric
shock.
R WARNING! NEVER operate the transceiver during a
lightning storm. It may result in an electric shock, cause
a re or damage the transceiver. Always disconnect the
power source and antenna before a storm.
R WARNING! NEVER connect the transceiver to a power
source of more than 16 V DC such as a 24 V battery. This
could damage the transceiver.
R WARNING! 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.
R WARNING! NEVER place the transceiver where normal
operation of the vehicle may be hindered or where it could
cause bodily injury.
CAUTION: DO NOT expose the transceiver to rain, snow
or any liquids.
CAUTION: DO NOT use the non-specied microphone
only. Other microphones have different pin assignments
and may damage the radio.
CAUTION: DO NOT place or leave 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.
CAUTION: DO NOT operate the transceiver without
running the vehicle’s engine. The vehicle’s battery will
quickly run out when the transceiver transmits while the
vehicle’s engine is OFF.
CAUTION: DO NOT place or leave the transceiver in
excessively dusty environments.
CAUTION: DO NOT place the transceiver against walls.
Otherwise heat dissipation will be obstructed.
CAUTION: DO NOT use harsh solvents such as
Benzine or alcohol when cleaning, as they damage the
transceiver’s surfaces.
CAUTION: CONFIRM that all connectors and jacks are
dry and clean before attachment. Exposing them to dust or
water will result in serious damage to the transceiver.
NEVER place the transceiver in an insecure place to avoid
inadvertent use by unauthorized persons.
BE CAREFUL! The transceiver will become hot when
operating continuously for long periods of time.
BE CAREFUL! DO NOT block the air vent when installing
the transceiver. This transceiver has an air vent on
the bottom panel of the transceiver to meet the IP55
requirements.
CAUTION: Hot surfaces. DO NOT touch
the transceiver’s surface after continuously
transmitting for long periods of time. The
transceiver’s chassis radiates heat, and it
will become hot to protect the power
amplier unit from overheating. Touching it
may cause a burn.

SAFETY TRAINING INFORMATION
Your Icom radio generates RF
electromagnetic energy during
transmit mode. This radio is designed
for and classied as “Occupational
Use Only”, meaning it must be used
only during the course of employment
by individuals aware of the hazards,
hazards. This radio is NOT intended for use by the
“General Population” in an uncontrolled environment.
For compliance with FCC and IC RF Exposure
Requirements, the transmitter antenna installation shall
comply with the following three conditions:
1. The transmitter antenna gain shall not exceed 0 dBi.
2. IC-F5400D series:
The antenna is required to be located outside of a
vehicle and kept at a distance of 57 centimeters (23
inches) or more between the transmitting antenna of
this device and any persons during operation. For small
vehicle as worst case, the antenna shall be located on
the roof top at any place on the center line along the
vehicle in order to achieve 57 centimeters (23 inches)
separation distance. In order to ensure this distance is
met, the installation of the antenna must be mounted at
least 57 centimeters (23 inches) away from the nearest
edge of the vehicle in order to protect against exposure
to bystanders.
2. IC-F6400D series:
The antenna is required to be located outside of a
vehicle and kept at a distance of 42 centimeters
(17 inches) or more between the transmitting antenna of
this device and any persons during operation. For small
vehicle as worst case, the antenna shall be located on
the roof top at any place on the center line along the
vehicle in order to achieve 42 centimeters (17 inches)
separation distance. In order to ensure this distance is
met, the installation of the antenna must be mounted at
least 42 centimeters (17 inches) away from the nearest
edge of the vehicle in order to protect against exposure
to bystanders.
3. IC-F5400D series:
Transmit only when people outside the vehicle are
at least the recommended minimum distance of 136
centimeters (54 inches) away from the properly installed
antenna. This separation distance will ensure that
there is sufcient distance from a properly installed
externally-mounted antenna to satisfy the RF exposure
requirements in the applicable RF exposure compliance
standards.
3. IC-F6400D series:
Transmit only when people outside the vehicle are
at least the recommended minimum distance of 119
centimeters (47 inches) away from the properly installed
antenna. This separation distance will ensure that
there is sufcient distance from a properly installed
externally-mounted antenna to satisfy the RF exposure
requirements in the applicable RF exposure compliance
standards.
and the ways to minimize such
To ensure that your exposure to RF
electromagnetic energy is within the
FCC and IC allowable limits for
occupational use, always adhere to
the following guidelines:
• DO NOT operate the radio without a proper antenna
attached, as this may damage the radio and may also
cause you to exceed FCC and IC RF exposure limits. A
proper antenna is the antenna supplied with this radio by
the manufacturer or an 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 and IC RF exposure
compliance requirements to be exceeded. The radio is
transmitting when the status indicator lights red. You can
cause the radio to transmit by pressing the “PTT” switch.
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, aircraft, and
blasting sites.
FCC INFORMATION
This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when
the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation
of this equipment in a residential area is likely to cause
harmful interference in which case the user will be
required to correct the interference at his own expense.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the condition that this device does
not cause harmful interference.
CAUTION: Changes or modications to this transceiver,
not expressly approved by Icom Inc., could void
your authority to operate this transceiver under FCC
regulations.
