i
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.
TABLE OF CONTENTS
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 transmits 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.

■ Antenna
A key element in the performance of any communication system is an antenna. Ask your dealer about antennas and the
best places to mount them.
■ Fuse replacement
Two fuses are installed in the supplied DC power cable. If a
fuse blows or the transceiver stops functioning, track down
the source of the problem if possible, and replace the damaged fuse with a new rated one.
❑ Fuse rating : 15 A (IC-F610/F620), 20 A (IC-F621)
■ Cleaning
If the transceiver becomes dusty or dirty, wipe it clean with a
dry, soft cloth.
AVOID the use of solvents such as benzene or
alcohol, as they may damage transceiver surfaces.

SAFETY TRAINING INFORMATION
WARNING
CAUTION
3
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 employ-
ment by individuals aware of the hazards,
and the ways to minimize such hazards. This radio is
NOT intended for use by the “General Population” in an
uncontrolled environment.
• For compliance with FCC and Industry Canada RF
Exposure Requirements, the transmitter antenna installation
shall comply with the following two conditions:
1. The transmitter antenna gain shall not exceed 0 dBi.
2. IC-F620:
The transmitter antenna is required to be located outside
of a vehicle and kept at a separation distance of 37 centimeters or more between the transmitter antenna of this
device and persons during operation.
2. IC-F621:
The transmitter antenna is required to be located outside
of a vehicle and kept at a separation distance of 50 centimeters or more between the transmitter antenna of this
device and persons during operation.
To ensure that your exposure 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 damage 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
an antenna specifically 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 the “TX 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.
