7.1.1. General
Precautions
The receiver cabinet is constructed to withstand the humid and corrosive marine
environment, but is designed to be installed or operated inside the wheelhouse or
chartroom. The cabinet is a “protected” category product under IEC 60945–2002, and is
not waterproof. Serious damage will result to the electronics inside the cabinet when it
is exposed to salt water spray or splash.
Additional Requirements:
(1) For long term trouble–free service, the proposed site for installation should be:
・
dry, well–ventilated and free as much as possible from shocks and engine
vibrations.
・
away as much as possible from high temperature outlets (such as exhaust fans
and heaters), and as much as possible from areas where the unit is likely to be
constantly exposed to direct sunlight.
(2) To prevent reception of weak NAVTEX signals from being interfered with, the unit
should also be located away as much as possible from other onboard electronics,
especially those emitting pulsed signals, such as echo sounders and radars.
7.1.2. Mounting the Receiver Cabinet
The receiver cabinet is primarily designed to be mounted on a tabletop with the
mounting bracket supplied and weights approximately 3.7 kg in total. The dimensions
necessary for installation are given in Figure 7–2. Provide sufficient clearance behind
the cabinet for cabling termination and maintenance checks.
Using a total of four appropriate wood screws or bolt/nut combinations through its four
mounting holes (9 mm in diameter each), secure the bracket to the selected site.
Make sure that the mounting surface is strong enough to support the unit against
shocks or vibrations that are likely to be encountered with the ship in motion.
Compass Safe Distances (in energized condition):
・
Receiver Cabinet alone:
0.60m ( standard), 0.40m ( steering)
・
Cabinet with Bracket:
0.80m ( standard), 0.45m
( steering)
< WARNINGS >
1. DO NOT PLACE THE UNIT IN AN UNVENTILATED, SEALED ENCLOSURE,
SUCH AS A THEFT–DETERRENT CABINET, OR OVERHEATING AND
MALFUNCTION WILL RESULT.
2. DAMAGE CAUSED BY EXPOSURE TO WATER SPRAY OR TO DIRECT
SUNLIGHT WILL NOT BE COVERED BY THE MANUFACTURER’S WARRANTY.
