							PRECAUTIONS
¥If you are connecting your MST660 for the first time or have just
reconnected your boat battery and you are experiencing problems with the
MST660Õs operation, we suggest you try resetting the unit. The reset
button is located under the removable face panel (see page 5 for
instructions on removing and refitting the face panel). Simply press the
reset button with a ball point pen or similar. You can then refit the
face panel.
¥Do not insert anything other than audio compact discs into the disc slot.
The CD mechanism contains precision laser equipment which could be
damaged by inserting foreign objects.
¥The station memories and clock time are retained only while the red
ÔBatteryÕ lead is connected (see Installation section). If the battery is
disconnected or switched off at the master switch, or if the unit is removed
from the vessel, the station memories will be lost and the clock will need to
be reset.
Handling Compact Discs
¥Handle the CD by its edge. Avoid touching the discÕs surface.
¥Store your CDs away from direct sunlight or heat sources. Keeping the CD
stored in its original case will help to keep it flat.
¥Clean the CD with a soft cloth. Clean from the center to the outer edge (see
diagram) rather than in a circular motion. Do not use solvents.

Moisture Condensation
Your MST660 uses optical laser technology. Occasionally, damp or humid
conditions may cause condensation to appear on the lenses inside the unit.
Should this occur, the unit may not operate correctly. Simply eject the CD and
leave the unit turned on for a while until the moisture evaporates.

INSTALLATION
Location
The MST660 is designed to be mounted in several different ways to enable it
to be installed in the most convenient position. Although the unit is water
resistant when the front cover is closed, care should be taken to locate it
where it will not be subjected to spray or rain. The unit should be mounted
with an angle of less than 20¡to the horizontal plane (see diagram) and in a
position that is free from direct sunlight and excessive vibration. 
Upright or Overhead Mounting
1.Attach the two gimbal knobs and the self-adhesive rubber washers to the
MST660 and slide the unit into the mounting bracket. Ensure the rubber
washers are between the bracket and the CD playerÕs case. Tighten the
knobs firmly.
2.Temporarily position the MST660 in the desired location and roughly mark
the location of the bracket edges. Now, remove the unit from the bracket
and reposition the bracket to mark the mounting hole positions. A range of
mounting holes is provided to suit most installations.
3.Screw or bolt the bracket into position. The mounting method will depend
on the material to which the bracket is being attached.
4.Slide the MST660 back into the bracket slots and adjust for the correct
position before tightening the gimbal knobs. Remember to avoid
exceeding the maximum mounting angle of 20¡.
5.Complete the antenna lead and electrical wiring as described later.

Flush Mounting
The MST660 can be neatly flush mounted into a panel or bulkhead so that just
the controls and the protective cover are visible. There are two flush mounting
options available. The best option for you will depend on your particular
situation.
¥If the space behind the bulkhead or panel you have selected has a suitable
support shelf and the area is fully accessible, you can use the supplied
escutcheon panel as described later.
¥If the space behind the bulkhead or panel is largely inaccessible or there is
no additional support shelf, we recommend you use the optional CMB60
flush mounting kit (available as an accessory). This kit is more robust, is
fully self supporting and allows the MST660 to be installed from the front.
Installation using the supplied Escutcheon Panel.
1.Select a suitable location on a panel or bulkhead. Examine behind the
bulkhead to determine the best method of support for the CD player.
2.Place the escutcheon on the panel or bulkhead in the required position
and mark around the outside edge of the escutcheon slot wall.
3.Remove the escutcheon and measure the marks. They should measure
approximately 7.87 wide and 2.76 high. If not, check the diagram above
to ensure that you measured the correct edge.

4.If your measurements are correct, carefully cut the slot around the marked
lines, ensuring that you maintain the curves in each corner. Mark and drill
the four 0.08 holes in the bulkhead to accept the locating pins at each
corner of the escutcheon.
5.Trial fit the escutcheon to ensure it fits securely against the panel. If all is
well, place a small dab of glue on each locating pin and press the
escutcheon into place. Temporarily hold with tape if necessary.
6.With the escutcheon firmly glued in place, slide the MST660 through the
slot from the front and push it all the way in, while leaving a clearance for
the front cover to hang in the open position. Open the cover if necessary
to ensure the correct clearance.
7.Holding everything in position, mark the location of the internal support
bracket(s). Drill the required holes and fit the bracket(s) as required to hold
the MST660 firmly in place.
Note: If using the perforated metal support strip, mount it to the rear of the
MST660 as shown in the diagram below.
8.Complete the antenna lead, speaker and power wiring as described later.
