peater.

SAVE THIS INSTRUCTION MANUAL– This

manual contains important safety and operating in­structions for the IC-FR3000/FR4000 series.

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.

RWARNING HIGH VOLTAGE! NEVER install

the antenna at any place that person touch the an­tenna easily 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-FR3000/FR4000 series may
damage the repeater.

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 equip­ment included with the IC-FR3000/FR4000 series, see
‘Supplied accessories’ on p. iii of this manual.

■ Selecting a location

Select a location for the repeater that allows adequate
air circulation, free from extreme heat, cold, or vibra­tions, and away from TV sets, TV antenna elements,
radios and other electromagnetic sources.

■ Antenna connection

For radio communications, the antenna is of critical im­portance, along with output power and sensitivity. Se­lect antenna(s), such as a well-matched 50 Ω antenna,
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 recom­mendations.

■ Duplexer

A duplexer is separately required when only one an­tenna is used for both transmitting and receiving. Se­lect a duplexer according to the transmitting and re­ceiving frequencies. Ask your Dealer for details.

■ Grounding

To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other prob­lems, ground the transceiver through the [GND] termi­nal on the rear panel.

For best results, connect a heavy gauge wire or strap
to a long earth-sunk copper rod. Make the distance be­tween the [GND] terminal and ground as short as pos­sible.

RR

WARNING: NEVER connect the [GND] termi-

nal 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-FR3000/FR4000 series can operate with an AC
or DC power supply. If AC power is interrupted when
operating the repeater with an AC power supply, power
is automatically 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.

D In 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. Dis­charging is therefore prevented even if the battery is
not used for a long time.

D In 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.

• When connecting to the battery, keep in order to con-

nect the DC power cable to the repeater first, then
the positive (red) terminal and negative (black) termi­nal to the battery to prevent an electric shock.

• After the battery is connected and the [POWER]

switch is ON, the repeater continuously supplies ap­prox. 1 A for charging the battery. If the repeater
stops functioning while connected to the battery, dis­connect the battery, recharge it, then connect the bat­tery to continue operation after the battery is charged.
During repeater transmission, approx. 17 A of battery
power is consumed.

■ Mounting the repeater

OPTIONAL UNIT INSTALLATION

■ Opening the repeater’s case

Follow the case and cover opening procedures shown
here when an optional unit is installed or adjust the in­ternal units, etc.

CAUTION: DISCONNECT the AC power cable
and/or DC power cable from the repeater. Other­wise, there is danger of electric shock and/or equip­ment damage.

q Remove 6 screws from the top of the repeater and

4 screws from the sides, then lift up the top cover.

w Turn the repeater upside down.
e Remove 6 screws from the bottom of the repeater,

and 4 screws from the sides, then lift up the bot­tom cover.

■ Voice scrambler unit
installation

The UT-109 (#01)/UT-110 (#01) provides high perfor­mance private communication for base operating
mode. In order to receive or send scrambled trans­missions, the UT-109 (#01)/UT-110 (#01) must be in­stalled and to activate the scrambler function.

q Remove the top and bottom covers as shown

above.

w Remove 8 screws from the LOGIC shielding plate,

then remove the plate.

e Cut the pattern on the PCB at the RX AF circuit

(CP1) and TX mic circuit (CP2) on the LOGIC unit
as shown at right.

r Turn the repeater upside down, then install the

scrambler unit as shown below.

t Return the LOGIC shielding plate, top and bottom

covers to their original positions.

NOTE: Be sure to re-solder
above disconnected points,
otherwise no TX modulation or
AF output is available when
you remove the scrambler unit.

OPERATION

■ Turning power ON

q Push [POWER] to turn power ON.
w If the repeater is programmed for a power on pass-

word by an Icom Dealer, input digit codes directly.

• The keys in the table below can be used for password
input.

• The repeater detects numbers in the same block as
identical. Therefore “01234” and “56789” are the same.

e When the “PASSWORD” indication does not clear

after inputting 4 digits, the input code number may
be incorrect. Turn power off and start over in this
case.

■ Receiving and transmitting

D Receiving

q Push [POWER] to turn power ON.

w Set the audio and squelch levels.

➥ Rotate [SQUELCH] fully counterclockwise in ad-

vance.

➥ Rotate [VOLUME] to adjust the audio output level.
➥ Rotate [SQUELCH] clockwise until the noise dis-

appears.

e Push [UP] or [DN] to select the desired channel.

•When receiving a signal, BUSY indicator turns ON and

audio is emitted from the speaker.

•Further adjustment of [VOLUME] to a comfortable listen-

ing level may be necessary at this point.

D Transmitting

q Take the microphone off hook.
w Wait for the channel to become clear.
e Push and hold [PTT] to transmit, then speak into the

microphone at your normal voice level.

r Release [PTT] to receive.

IMPORTANT:

To maximize the readability of the transmitted signal:
(1) Pause briefly after pushing [PTT].
(2) Hold the microphone 1 to 2 inch (2.5 to 5 cm) from

your mouth, then speak into the microphone at a
normal voice level.
