2 INSTALLATION AND CONNECTIONS ■ Unpacking ■ Duplexer After unpacking, immediately report any damage to the delivering carrier or dealer. Keep the shipping cartons. 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. For a description and a diagram of accessory equipment included with the IC-FR3100/FR4100 series, see ‘Supplied Accessories’ on p.

Used for external equipment control.
INSTALLATION AND CONNECTIONS ■ Power ■ Mounting the repeater Make sure the [POWER] switch is turned OFF when connecting an AC power cable and a backup battery (emergency power supply). D Using the optional MB-78 The IC-FR3100/FR4100 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.
2 INSTALLATION AND CONNECTIONS • Top side installation q Remove the screws (M4 × 8) from both sides of the MB-78. w Remove the handles from the bottom bar. And turn the handles upside down, then replace the handles right side and left side. t Remove the 2 screws (M4 × 8) from both sides of the side panel (front-end). y Attach the MB-78 to the top side of the repeater. Then tighten the supplied screws (M4 × 8) and 2 screws removed from each side of the repeater.
INSTALLATION AND CONNECTIONS 2 D Using the optional MB-77 An optional MB-77 WALL MOUNT BRACKET is available for mounting the repeater to a flat surface. RWARNING: NEVER mount the repeater on the MB-77 by yourself. At least two people are required to mount the repeater since it weights approx. 12 kg. q Attach the hinges on the right side of the repeater as shown below. w Tighten the 2 supplied screws (M5 × 12) for each hinge. e Put the MB-77 on the wall (or wherever you plan to mount the repeater).
3 OPTIONAL UNIT INSTALLATION ■ Opening the repeater’s case Follow the case and cover opening procedures shown here when an optional unit is installed or when adjusting 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.
OPERATION 4 ■ Turning power ON q Push [POWER] to turn the power ON. w If the repeater is programmed for a power on password by an Icom Dealer, input the digit codes directly. • The keys in the table below can be used for password input. • The repeater detects numbers in the same block as KEY NUMBER [DN] [UP] 0 5 1 6 [MONI] [RPT/BASE] [REMOTE] 2 7 3 8 4 9 identical. Therefore “01234” and “56789” are the same.
5 MAINTENANCE ■ Troubleshooting The following chart is designed to help correct problems 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 nearest Icom Dealer or Service Center. PROBLEM POSSIBLE CAUSE Power does not come on when [POWER] switch is • DC power cable is improperly connected. ON. • Fuse is blown. SOLUTION • Re-connect the DC power cable correctly. REF. p.
MAINTENANCE 5 ■ Fuse replacement If a fuse blows or the repeater stops functioning, try to find the source of the problem, and replace the damaged fuse with a new, rated fuse. RWARNING: DISCONNECT the AC power cable and/or DC power cable from the repeater. Otherwise, there is danger of electric shock and/or equipment damage. D LOGIC unit D REG unit q Remove the bottom cover as shown on p. 11. w Remove 8 screws from the LOGIC shielding plate, then remove the plate.

8 ABOUT CE INSTALLATION NOTES • Compliance of base station transmitter installations with EN50385 The installation of this equipment and it’s associated antenna should be made in such a manner as to respect the EC recommended electromagnetic (EM) field exposure limits.
ABOUT CE • Typical installation example A UHF base station transmitter is to be installed on the roof of an office. The transmit power is 25 watts, there is 20 m of RG213 coaxial cable and the antenna is vertically polarised dipole. The specification of the RG-213 cable gives a loss of 1.5 dB/10 m. There will be 3 dB loss for the 20 m length used. The RF power at the antenna input will be 12.5 watts. The dipole antenna has a forward gain of 0 dBd or 1.6, giving an EIRP of 20 watts.
