FCC INFORMATION
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause
harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment o and on, the user
is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit dierent
from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician
for help.
CAUTION: Changes or modications to this repeater,
not expressly approved by Icom Inc., could void your
authority to operate this repeater under FCC regulations.

REPLACING FUSE
If a fuse blows, or the repeater stops functioning, nd
the source of the problem, repair it, and then replace the
damaged fuse with a new rated one.
CAUTION: DO NOT replace the fuse with the DC
power cable connected to the power source. Disconnect
the cable to prevent electric shock and/or equipment
damage.
USE only a specified fuse.
Fuse rating: 32 V 20 A
PRECAUTIONS
R WARNING HIGH RF VOLTAGE! NEVER touch an
antenna or antenna connector while transmitting. This
could cause an electrical shock or burn.
R WARNING HIGH RF VOLTAGE! NEVER install the
antenna at any place that person easily touch the antenna
while transmitting. This could cause an electrical shock or
burn.
R WARNING! NEVER apply AC power to the DC power
receptacle on the repeater rear panel. This could cause a
re or damage the repeater.
R WARNING! NEVER apply more than 16 V DC to the DC
power receptacle on the repeater rear panel. This could
cause a re or damage the repeater.
R WARNING! NEVER remove the fuse holder on the DC
power receptacle on the repeater rear panel. Excessive
current caused by a short could cause a re or damage
the repeater.
R WARNING! NEVER reverse the DC power cable
polarity. This could cause a re or damage the repeater.
R WARNING! NEVER let metal, wire or other objects
contact the inside of the repeater, or make incorrect
contact with connectors on the rear panel. This could
cause an electric shock or damage the repeater.
R WARNING! NEVER operate or touch the repeater with
wet hands. This could cause an electric shock or damage
to the repeater.
R WARNING! NEVER operate the repeater if you notice
an abnormal odor, sound or smoke. Immediately turn OFF
the power and/or remove the DC power cable. Contact
your Icom dealer or distributor for advice.
R WARNING! NEVER put the repeater on an unstable
place where the repeater may suddenly move or fall. This
could cause an injury or damage the repeater.
CAUTION: DO NOT expose the repeater to rain, snow or
any liquids. They could damage the repeater.
CAUTION: DO NOT use or leave the repeater in areas
with temperatures below –25°C (–13°F) or above +55°C
(+131°F): European or Australian versions, below –30°C
(–22°F) or above +60°C (+140°F): other versions. Be
aware that temperatures can exceed 80°C (+176°F),
resulting in permanent damage to the repeater if left there
for extended periods.
CAUTION: DO NOT place or leave the repeater in
excessively dusty environments. This could damage the
repeater.
CAUTION: DO NOT use harsh solvents such as benzine
or alcohol when cleaning. This could damage the repeater
surfaces. If the surface becomes dusty or dirty, wipe it
clean with a soft, dry cloth.
CAUTION: DO NOT put anything on top of the repeater.
This will obstruct heat dissipation.
CAUTION: DO NOT use non-Icom microphones. Other
manufacturer’s microphones may have dierent pin
assignments, and could damage the connector and/or the
repeater.
BE CAREFUL! The heatsink will become hot when
continuously operating the repeater for long periods of
time.
NEVER leave the repeater in an insecure place to avoid
use by unauthorized persons.
For European versions
CAUTION: Hot surfaces. DO NOT touch the
repeater’s surface after continuously
transmitting for long periods of time. The
repeater’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
CAUTION
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
WARNING
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 two conditions:
1. The transmitter antenna gain shall not exceed 0 dBi.
2. UR-FR5300:
Transmit only when people are at least the
2. UR-FR6300:
Transmit only when people are at least the
• 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 “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 o
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.

ways to minimize such hazards.
recommended minimum distance of 60 centimeters
away from the properly installed antenna. This
separation distance will ensure that there is sucient
distance from a properly installed externally-mounted
antenna to satisfy the RF exposure requirements in
the applicable RF exposure compliance standards.
recommended minimum distance of 50 centimeters
away from the properly installed antenna. This
separation distance will ensure that there is sucient

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:
POWER SUPPLY CONNECTION
