1. HOW TO INSTALL THE
EQUIPMENT
This chapter shows you how to install the units of the system. The transceiver unit and
handset are standard supply. All other units are optional supply. (The junction box is
standard supply in some installations.)
1.1 Transceiver Unit FM-8900S
1.1.1 General installation remarks
The transceiver unit can be installed on a desktop (with hanger), under a desktop,
overhead, bulkhead, or in a console (requires a flush mount kit). Select a location
where the controls can be easily operated and a location that is near the power source
and the ground location. Additionally, select a location that meets the following condi-
tions:
1.1.2 Desktop, bulkhead, overhead installation
1. Use the hanger as a template to mark the fixing holes in the installation location.
2. Fix the hanger to the location with the self-tapping screws and washers (supplied).
(For the overhead mount, use nuts, bolts and washers instead of the self-
tapping screws.)
3. Screw the knob bolts with the washers into the transceiver unit.
4. Set the transceiver unit to the hanger and tighten the knob bolts.
• Select a location away from water spray and water splash.
• The location must not be in direct sunlight, because of heat that can increase inside the unit.
• Leave some additional length in cables to allow a service technician to move the radio from its nor-
mal location with the cables connected.
• Do not install the unit where flammable gases are stored.
• Select a location that provides good ventilation.
• Make sure the location can hold the weight of the unit under the condition of continued vibration
normally found on the ship. If necessary, strengthen the location. For added support use nuts, bolts
and washers (instead of self-tapping screws) to fasten the unit.
• Leave enough space at the sides and rear of the unit for maintenance and service purposes and
to provide cool air. See the outline drawings at the back of this manual for recommended service
space.
• For Solas Convention vessels, the mounting location must satisfy the conditions of Regulations 22
Navigation bridge visibility.
• For installation in a console, select a location where the display can be easily seen.
• The transceiver unit causes interference to a magnetic compass if put too close to the compass.
Follow the compass safe distance in the safety instructions to prevent interference to a magnetic
compass.

1.1.3 Console installation (flush mount, option)
Requires the optional flush mount kit (OP05-129), the contents of which are shown in
the table below. Follow the instructions in the outline drawing to install the unit in a con-
sole.
1.2 VHF Antenna
1.2.1 Requirements for the antenna
Any good quality antenna that meets the requirements shown below can be used.
1.2.2 Installation location
The location and installation of different antennas on a ship is important to ensure ef-
fective communications. Incorrectly installed antennas will degrade performance of
the radio equipment and reduce the range of communications.
Select the location for the antenna considering the following points.
• VHF antennas should be placed in a position which is as elevated and free as pos-
sible, with at least 2 meters horizontal separation from constructions made by con-
ductive materials.
• Ideally there should not be more than one antenna on the same level.
• The location of mandatory VHF antennas should be given priority compared with
mobile telephone antennas. If they are located on the same level, the distance be-
tween them should be at least 5 meters.

easy access to the front panel controls while you operate the handset. The length of
the standard handset cable is 50 cm. Put the handset hanger within 50 cm of the unit.
(Longer cables are available.)
1.5 AC-DC Power Supply Unit PR-240
For Solas Convention vessels, both AC and DC power must be supplied to the trans-
ceiver unit, through an AC/DC power supply. When the AC input fails, DC power is
supplied. FURUNO can supply an AC/DC power supply unit, the PR-240. Provide pro-
tective earth. See chapter 2.
1.5.1 Installation location
Select the location that meets the following conditions:
• Select a location that provides good ventilation.
• The location must be clean and dry.
• Make sure the location can hold the weight of the unit under the condition of contin-
ued vibration normally found on the ship.
• The power supply unit will affect the performance of a magnetic compass if put near
the compass. Follow the compass safe distance in the safety instructions to prevent
the interference to a magnetic compass.
