25INSTALLATION AND CONNECTIONS■UnpackingAfter unpacking, immediately report any damage to thedelivering 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. iii of this manual.■Selecting a locationSelect a location for the repeater that allows adequateair circulation, free from extreme heat, cold, or vibra-tions, and away from TV sets, TV antenna elements,radios and other electromagnetic sources.■Antenna connectionFor 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 WaveRatio (VSWR) is recommended for desired band. Ofcourse, the transmission line should be a coaxialcable.CAUTION: Protect repeater from lightning by usinga lightning arrestor.NOTE: There are many publications coveringproper antennas and their installation. Check withyour local dealer for more information and recom-mendations.■DuplexerA 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.■GroundingTo 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 strapto 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] terminalto a gas or electric pipe, since the connection couldcause an explosion or electric shock.TX/TX•RXEXT SP REMOTEACC RXGNDACBATTERYTYPE-N CONNECTOR INSTALLATION EXAMPLE30 mm ≈9⁄8in 10 mm ≈3⁄8in 1–2 mm ≈1⁄16 inSlide the nut, flat washer, rubber gasket and clamp over the coaxial cable, then cut the end of the cable evenly.Strip the cable and fold the braid back over the clamp.Soft solder the center conductor.

82INSTALLATION AND CONNECTIONS■PowerMake sure the [POWER] switch is turned OFF whenconnecting an AC power cable and a backup battery(emergency power supply).The IC-FR4000 series can operate with an AC or DCpower 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 andOFF quickly, the repeater may not turn ON. In thiscase turn OFF the power switch and wait for awhile, then turning power ON again.DIN AC OPERATION• The [DC] indicator turns OFF.• Use the supplied AC power cable for connection to adomestic AC outlet.• Extension cords should not be used unless ab-solutely necessary. Using improper extension cordscould result in fire risk.• Usually the battery is continuously charged with asmall amount of current from an AC power supplythrough the regulator circuit in the repeater. Dis-charging is therefore prevented even if the battery isnot used for a long time.DIN DC OPERATIONCAUTION: Voltages greater than 16 V DC will dam-age the repeater. Check the source voltage beforeconnecting 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 least5 m (16.4 ft.) away from the repeater. Use a heavyduty cable to make the connection and be sure boththe positive (red) and negative (black) terminals arecorrectly connected.• When connecting to the battery, keep in order to con-nect the DC power cable to the repeater first, thenthe positive (red) terminal and negative (black) termi-nal to the battery to prevent an electric shock.• 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 repeaterstops 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 batterypower is consumed.■Mounting the repeaterDUsing the optional MB-78An optional MB-78 19 INCH RACK MOUNT BRACKETisavailable for mounting the repeater into a 19 inch rack.The MB-78 can install the repeater’s bottom side andtop side.• Bottom side installationqRemove the 2 screws (M4 ×8) from both side of theside panel (front-end).wAttach the MB-78 to the bottom side of the repeater.eTighten the 1 supplied screws (M4 ×8) and 2 re-moved screws to each side.
