1. HOW TO INSTALL THE SYSTEM

Installation requirements for whip antenna

• The installation arrangement of the antenna or pedestal must be constructed to
withstand the strain from swaying and vibration.
• Locate the antenna in an elevated position on the ship and at least one meter away
from conductive structures.
• Run the down lead from the base of the antenna to the coupler as vertically as pos-
sible. In the COSAR Circ.32, it is recommended that the down lead should be more
than 45 degrees towards the horizontal plane.
• For indoor installation, use a lead-in insulator (FURUNO type: YA-256) to make the
connection. If necessary, use a high quality antenna switch and stand-off insulator.
• It is recommended to construct an enclosure around the whip antenna to prevent
contact with the antenna. Also, post a weather resistant "DANGER HIGH VOLT-
AGE" sign on the enclosure.

RX antenna

An RX antenna is required for duplex communications (FS-5075).

How to Install Optional Equipment

1.6.1

Preamp Unit FAX-5

The preamp unit can be mounted two ways as shown below. For detailed installation
procedure, see the outline drawing for the preamp unit.
• Screw onto a pipe (φ27.2 mm) with Whitworth fine screw threads (W25-14) whose
length is 50 mm.
Note: The mast should not be longer than 1.5 m (5 feet) to prevent undue flexing in
heavy winds.
• Fix to a mast (φ35 to 90 mm), using stainless steel hose clamps (optional supply).
1.6.2 Printer PP-520
Refer to the outline drawing at the end of this manual for mounting dimensions and
recommended maintenance space. Follow the compass safety distance shown in the
Safety Instructions to prevent interference to a magnetic compass. Connect the inter-
connection cable between the printer and the Control Unit (or Printer Interface). For
how to load paper and set ribbon cassette, refer to the Operator's Manual of the print-
er.
Set the fixtures (left/right) onto the printer. Fasten them with four self-tapping screws
(φx20).
