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. I 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. I 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 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 recom-
mendations. TYPE-N CONNECTOR INSTALLATION EXAMPLE I 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. I 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.

Bottom side installation q Remove the 2 screws (M4 8) from both side of the side panel (front-end). w Attach the MB-78 to the bottom side of the repeater. e Tighten the 1 supplied screws (M4 8) and 2 re-
moved screws to each side. (6 screws at total) r The completed bottom side installation should look like below. I 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. 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 re 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. 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) 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 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. 8 2 INSTALLATION AND CONNECTIONS Top side installation q Remove the 1 screw (M4 8) from both side of the MB-78. t Remove the 2 screws (M4 8) from both side of the side panel (front-end). w Remove the handles from bottom bar.
