structions for the IC-FR4000.
EXPLICIT DEFINITIONS
RWARNING HIGH VOLTAGE! NEVER at-
tach an antenna or internal antenna connector during
transmission. This may result in an electrical shock or
burn.
RNEVER apply AC to the [BATTERY] terminals on
the repeater rear panel. This could cause a fire or
damage the repeater.
RNEVER 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 re-
peater.
RNEVER let metal, wire or other objects touch any
internal part or connectors on the rear panel of the re-
peater. This may result in an electric shock.
RNEVER expose the repeater to rain, snow or any
liquids.
AVOID using or placing the repeater in areas with tem-
peratures 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 per-
manent damage to the repeater if left there for ex-
tended periods.
AVOID placing the repeater in excessively dusty envi-
ronments 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 inadver-
tent use by children.
BE CAREFUL! The heatsink will become hot when op-
erating 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 manu-
facturer’s microphones have different pin assignments,
and connection to the IC-FR4000 may damage the re-
peater.
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 regula-
tions.

INSTALLATION AND CONNECTIONS
■Unpacking
After unpacking, immediately report any damage to the
delivering carrier or dealer. Keep the shipping cartons.
For a description and a diagram of accessory equip-
ment included with the IC-FR4000, see ‘Supplied ac-
cessories’ on p. ii of this manual.
■Selecting a location
Select a location for the repeater that allows adequate
air circulation, free from extreme heat, cold, or vibra-
tions, and away from TV sets, TV antenna elements,
radios and other electromagnetic sources.
■Antenna connection
For radio communications, the antenna is of critical im-
portance, along with output power and sensitivity. Se-
lect antenna(s), such as a well-matched 50 Ωantenna,
and feedline. 1.5:1 or better of Voltage Standing Wave
Ratio (VSWR) is recommended for desired band. Of
course, the transmission line should be a coaxial
cable.
CAUTION: Protect repeater from lightning by using
a lightning arrestor.
NOTE: There are many publications covering
proper antennas and their installation. Check with
your local dealer for more information and recom-
mendations.
■Duplexer
A duplexer is separately required when only one an-
tenna is used for both transmitting and receiving. Se-
lect a duplexer according to the transmitting and re-
ceiving frequencies. Ask your Dealer for details.
■Grounding
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other prob-
lems, ground the transceiver through the [GND] termi-
nal on the rear panel.
For best results, connect a heavy gauge wire or strap
to a long earth-sunk copper rod. Make the distance be-
tween the [GND] terminal and ground as short as pos-
sible.
RWARNING: NEVER connect the [GND] terminal
to a gas or electric pipe, since the connection could
cause an explosion or electric shock.

INSTALLATION AND CONNECTIONS
■Power
Make sure the [POWER] switch is turned OFF when
connecting an AC power cable and a backup battery
(emergency power supply).
The IC-FR4000 series can operate with an AC or DC
power supply. If AC power is interrupted when operat-
ing the repeater with an AC power supply, power is au-
tomatically provided to the [BATTERY] terminals.
NOTE: When repeat to turn the repeater ON and
OFF quickly, the repeater may not turn ON. In this
case turn OFF the power switch and wait for a
while, then turning power ON again.
DIN AC OPERATION
• The [DC] indicator turns OFF.
• Use the supplied AC power cable for connection to a
domestic AC outlet.
• Extension cords should not be used unless ab-
solutely necessary. Using improper extension cords
could result in fire risk.
• Usually the battery is continuously charged with a
small amount of current from an AC power supply
through the regulator circuit in the repeater. Dis-
charging is therefore prevented even if the battery is
not used for a long time.
DIN DC OPERATION
CAUTION: Voltages greater than 16 V DC will dam-
age the repeater. Check the source voltage before
connecting the power cable.
• The [DC] indicator lights up green.
• DO NOT place the backup battery on or near the re-
peater. Lead-acid batteries should be placed at least
5 m (16.4 ft.) away from the repeater. Use a heavy
duty cable to make the connection and be sure both
the positive (red) and negative (black) terminals are
correctly connected.
• After the battery is connected and the [POWER]
switch is ON, the repeater continuously supplies ap-
prox. 1 A for charging the battery. If the repeater
stops functioning while connected to the battery, dis-
connect the battery, recharge it, then connect the bat-
tery to continue operation after the battery is charged.
During repeater transmission, approx. 17 A of battery
power is consumed.

The following chart is designed to help correct prob-
lems which are not equipment malfunctions.
If you are unable to locate the cause of a problem or
solve it through the use of this chart, contact the near-
est Icom Dealer or Service Center.
Power does not come on
when [POWER] switch is
ON.
No sounds from the
speaker.
Sensitivity is low and
only strong signals are
audible.
Received signal cannot
be understood.
Output power is too low.
No contact possible with
another station.
<DC operation>
• DC power cable is improperly connected.
<AC/DC common>
• Fuse is blown.
• Volume level is too low.
• The squelch is closed.
• The audio mute function is activated.
•A selective call or squelch function is acti-
vated such as 2/5 tone call or tone squelch.
• While in base operating mode, the repeater
is in the transmitting condition.
• Antenna feedline or the antenna connector
has a poor contact or short-circuited.
• Optional voice scrambler is turned OFF.
• Scrambler code is not set correctly.
• Output power is set to Low.
• The other station is using tone squelch.
• While in base operating mode, the repeater
is set to duplex.
• Re-connect the DC power cable correctly.
• Check the cause, then replace the fuse with
a spare one. (Fuses are installed in the inter-
nal REG unit and LOGIC unit.)
• Rotate [VOLUME] clockwise to obtain a suit-
able listening level.
•While in base operating mode, rotate
[SQUELCH] to counterclockwise to open the
squelch.
• While in repeater operating mode, adjust the
squelch threshold level on the set mode to
open the squelch.
• Push [SP MUTE] to the audio mute function
OFF
• Turn the appropriate function OFF.
• Push [PTT] on the microphone to receive or
check the PTT line of an external unit, if con-
nected.
•Check and re-connect (or replace if neces-
sary), the antenna feedline or antenna con-
nector.
