IMPORTANT

READ THIS INSTRUCTION MANUAL
CAREFULLY before attempting to operate the re-

peater.

SAVE THIS INSTRUCTION MANUAL– This

manual contains important safety and operating in­structions for the IC-FR4000.

EXPLICIT DEFINITIONS

R WARNING HIGH VOLTAGE! NEVER at-

tach an antenna or internal antenna connector during
transmission. This may result in an electrical shock or
burn.

R NEVER apply AC to the [BATTERY] terminals on

the repeater rear panel. This could cause a fire or
damage the repeater.

R NEVER apply more than 16 V DC, such as a 24 V

battery, to the [BATTERY] terminals on the repeater
rear panel. This could cause a fire or damage the re­peater.

R NEVER let metal, wire or other objects touch any

internal part or connectors on the rear panel of the re­peater. This may result in an electric shock.

R NEVER expose the repeater to rain, snow or any

liquids.

AVOID using or placing the repeater in areas with tem­peratures below –30°C (–22°F) or above +60°C
(+140°F). Be aware that temperatures on a vehicle’s
dashboard can exceed 80°C (+176°F), resulting in per­manent damage to the repeater if left there for ex­tended periods.

AVOID placing the repeater in excessively dusty envi­ronments or in direct sunlight.

AVOID putting anything on top of the repeater. This will
obstruct heat dissipation.

Place the repeater in a secure place to avoid inadver­tent use by children.

BE CAREFUL! The heatsink will become hot when op­erating the repeater continuously for long periods.

BE CAREFUL! If a linear amplifier is connected, set
the repeater’s RF output power to less than the linear
amplifier’s maximum input level, otherwise, the linear
amplifier will be damaged.

Use Icom microphones only (optional). Other manu­facturer’s microphones have different pin assignments,
and connection to the IC-FR4000 may damage the re­peater.

For U.S.A. only

CAUTION: Changes or modifications to this repeater,
not expressly approved by Icom Inc., could void your
authority to operate this repeater under FCC regula­tions.

Thank you for purchasing this Icom product. The IC­FR4000

UHF FM REPEATER

is designed and built with
Icom’s state of the art technology and craftsmanship.
With proper care, this product should provide you
years of trouble-free operation.

We want to take a couple of moments of your time to
thank you for making the IC-FR4000 your repeater of
choice, and hope you agree with Icom’s philosophy of
“technology first.” Many hours of research and devel­opment went into the design of your IC-FR4000 series.

FEATURES

❍ Highly efficient and stable output power

Icom’s expertise in radio technology has produced
the IC-FR4000, an FM repeater highly efficient and
completely stable with a PA module used in the
transmitter output circuit.

❍

2-way power supply system

The repeater has two-way, AC and DC power source
capability. If AC power to the repeater is interrupted,
DC power can be automatically connected as a
backup power source.

❍ Heavy duty power supply

A heavy duty power supply unit is adopted to follow
load fluctuations and secure continuous 24-hour op­eration.

❍ Other features

- PC programmable

- Wall or rack mount (optional MB-77/MB-78)

- Optional Voice Scrambler Unit (UT-109 #01/UT-110
#01) for base operating mode
