Fixing holes inside szcanner unit

This method requires removal of the RF unit in the scanner unit to access inside fixing holes. Use hex head bolts, flat washers, spring washers and nuts (local supply) to mount the scanner unit, confirming lengh of bolts.

1.Loose four scanner bolts to open the scan- ner unit. Refer to Figure 11 for location.

1.5 Display Unit Mounting

Mounting considerations

When selecting a mounting location for the display unit keep in mind the following points:

• Provide adequate space behind and

around the unit to permit circulation of air

and to provide convenient access to the

rear connection.

• Even though the picture is quite legible

even in bright sunlight, keep the display

unit out of direct sunlight or at least shaded

because of heat that can build up inside

the cabinet.

• Locate the display unit in a position where

you can view and operate it conveniently

but where there is no danger of salt or

fresh water spray or immersion.

• The orientation of the display unit should

be so the radar screen is viewed while the

2.Unplug connector connected between up- per and lower chassis.

3.Separate upper chassis from lower chas- sis by removing two hex head bolts.

4.Remove cover by unfastening four pan head screws.

5.Remove connector from RF unit .

6.Remove RF unit by unfastening four hex head bolts.

7.Lay the corrosion-proof rubber mat (sup- plied) on the mounting platform.

8.Fasten the lower chassis to the mounting platform with hex head bolts, spring washers, flat washers and nuts (local sup- ply ), and then coat flat washers, nuts and exposed parts of bolts with anticorrosive sealant. Cut a slit in rubber bushing and insert bolt into bushing. Do not use seal washers.

9.Reassemble RF unit, cover and upper chassis.

10.Set four knob caps (supplied) into outside fixing holes.

11.Do steps 6-8 in “Outside fixing holes”.

operator is facing in the direction of the

bow. This makes determination of your

position much easier.

• Make sure you allow enough clearance

both to get to the connectors behind the

unit and to allow you to get your hands in

on both sides to loosen or tighten the

mounting knobs. Make sure you leave at

least a foot or so of “service loop” of cables

behind the unit so it can be pulled forward

for servicing or easy removal of the con-

nectors.

• The compass safe distance of 0.75 meters

(standard compass) and 0.6 meters (steer-

ing compass) should be observed to pre-

vent deviation of the magnetic compass.

• Even though the display unit meets wa-

terproof standard IPX-5, the connection of

external buzzer, radar plotter and/or re-

mote display can affect waterproofness.

Watertight integrity cannot be guaranteed.

When these modification has been done,

the display unit should not be mounted

where exposed.

Mounting

The display unit is designed to be mounted on a tabletop or bulkhead.

1.Using the hanger as a template, mark screw locations in the mounting location.

2.Fix the hanger to the mounting location with five M6 tapping screws (supplied).

3.Fit the knob bolts to the display unit. In- stall the display unit in the hanger. Tighten the knob bolts securely.
