LISTENING TO FM ON YOUR BOAT
The majority of FM broadcasts are music programs. Compared with AM
signals, FM signals have a wider dynamic range, are relatively immune to noise
and provide virtually distortion-free music reproduction. However, because of
the nature of FM signals and the fact that FM stations are usually positioned
for shore-based reception, receiving them in a moving boat may be
accompanied by problems.
●FM programs are broadcast for local reception and cannot be heard
satisfactorily at distant locations. To enjoy FM programs at their best, it is
important that you tune to a station that is broadcasting in your locality.
●FM signals can reflect from solid objects such as buildings or hills. If these
reflected signals are received along with signals arriving directly from the
transmitter, they may mix together to produce what is known as "multipath
distortion". This distortion is heard as noise. Often moving as little as 3 feet
from your position will correct this problem.
●FM signals travel in straight lines. Because the signals are reflected from
or absorbed by large solid objects, a signal shadow may be present
behind the object which may result in poor reception in that area.
CASSETTE CARE AND MAINTENANCE
1. Tapes no longer than C-90 (90 minutes playing time) are recommended.
Avoid using C-120 tapes because they are extremely thin and may jam
your cassette player mechanism.
2. The most common cause of poor sound reproduction is a contaminated
tape head. Signs of contamination include low volume on one or both
channels and failure to reproduce high frequency notes. The head can be
cleaned using a cotton applicator soaked in alcohol. If the cassette unit is
used for more than one hour each day, the head should be cleaned once
or twice a month.
3. To extend the life of your cassettes, keep them away from:
●areas exposed to the sun
●top of instrument panels
●the engine
●areas exposed to heat and moisture
●magnetic fields (such as speakers)
4. Replace tapes in their plastic cases when not in use.
5. Do not oil revolving parts.

INSTALLATION
MOUNTING
The MST65 is designed to be mounted in several different ways so that it can
be installed in the most convenient position. Although the MST65 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. Figure 1 shows the various
methods of mounting available.
Figure 1. Upright or Overhead Mounting
Upright or Overhead Mounting
1. Attach the two gimbal knobs and self-adhesive rubber washers to the
MST65 and slide the unit into the mounting bracket. Ensure the rubber
washers are between the bracket and the radio. Tighten the knobs firmly.
2. Temporarily position the MST65 in the desired location, tilting the radio in
the bracket to ensure you are able to get the required adjustments for
viewing angle etc.
2808
3. Roughly mark the location of the bracket edges, then separate the radio
from the bracket and reposition the bracket to mark the mounting hole
positions. A range of mounting holes is provided to suit most installations.
4. Screw or bolt the bracket into position. The mounting method will depend
on the material to which the bracket is being attached.
5. Slide the MST65 back into the bracket slots and adjust to the required
position before tightening the gimbal knobs.
6. Connect the antenna lead and electrical wiring as described later.
Flush Mounting
The MST65 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 flush
mounting kit (available as an accessory). This kit is more robust, is fully self
supporting and allows the MST65 to be installed from the front.

Installation using the Supplied Escutcheon Panel
1. Select a suitable location on a panel or bulkhead.
2. Examine behind the bulkhead to determine the best method of support for
the radio. Examples of internal support methods are shown in Figure 2.
3. Place the escutcheon on the bulkhead or panel in the required position and
pencil around the outside edge of the escutcheon slot wall (see Figure 3).
4. Remove the escutcheon and measure your marks. They should measure
approximately 7 7/8 inches wide by 2 3/4 inches high. If not, check Figure
3 to ensure you measured the correct edge.
5. If your measurements are correct, carefully cut the slot around the marked
lines, ensuring that you maintain the curves in each corner.
6. Mark and drill four 1/8-inch holes in the bulkhead to accept the
escutcheon locating pins at each corner of the escutcheon.
7. Trial fit the escutcheon to ensure it fits securely against the panel. If all fits
well, put a small dab of glue on each locating pin and press the
escutcheon firmly into place. Temporarily hold in place with tape if
necessary.
8. With the escutcheon in place, slide the MST65 through the slot from the
front and push it almost as far as it will go. The radio should not be pushed
all the way in, to ensure there is adequate clearance for the front cover to
hang in the open position. Open the cover if necessary to check for the
correct clearance.
9. 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
firmly hold the MST65 in place.
10. Connect the antenna lead and electrical wiring as described later.
NOTE: Installation Instructions for the optional Flush Mount Kit are supplied
with the kit.

ELECTRICAL CONNECTION
FOR NEGATIVE GROUND ELECTRICAL SYSTEMS ONLY. See Figure 4.
The MST65 is intended for use in vessels with a 12 volt negative ground
electrical system. The Positive RED fused lead must be connected to the
positive (+) side of the electrical system and the Negative BLACK lead must be
connected to the ground negative (-) side. Reversal of these connections will
cause the fuse to blow and may seriously damage the unit, voiding the
warranty.
On smaller vessels, the negative BLACK lead can be connected directly to the
negative (-) terminal of the battery. The positive RED lead can go directly to the
battery positive (+) terminal, or if more convenient, to an accessory post on the
ignition switch.
On larger vessels with a switchboard, the negative lead should go to the
common negative bus and the positive lead to the switched and fused radio
(or spare) power circuit.
The orange fused lead is used to maintain the memories inside the radio and
must be connected to a continuous +12 Volt point such as the positive (+)
terminal of the battery.
NOTE: It is possible to use the MST65 on vessels with a 12 volt positive
ground electrical system, but special precautions are required when installing
the stereo system antenna and any accessories. If in doubt, consult a qualified
marine electronics technician.
FUSE REPLACEMENT
If any of the fuses blow, replace them as follows:
RED supply lead fuse: 7 Amp 3 AG type (1 3/16 inches)
ORANGE memory lead fuse: 1 Amp 3AG type (1 3/16 inches)

SPEAKER INSTALLATION
To obtain the best possible sound, flush-mount speakers should be mounted
in a bulkhead or panel to provide adequate isolation between the front and
rear of the speaker. A baffle area of approximately 2ft x 2ft is desirable when
bulkhead mounting. If mounting on a shelf or panel, the speaker can be
enclosed in a box, preferably with a volume area of 1 cubic foot.
Speakers which are fully enclosed in their own speaker boxes and incorporate
a gimbal mounting bracket can be mounted in any convenient location.
Although these speakers have water resistant cones, they should be mounted
in a sheltered position away from direct spray.
See Figure 5 for speaker connections.
WARNING
●Do not allow the speaker leads (even the common lead) to come into
contact with grounded metal on the vessel or the negative (-) supply. If any
speaker lead is connected to chassis ground, the amplifier in the MST65
will be damaged.
●Do not allow the speaker leads to "short" together as this will also cause
damage to the MST65 amplifier. Damage caused by the above may not be
covered by warranty.

Volume ON/OFF
Rotate the Volume knob clockwise to turn the unit on. Rotate the control
further to increase the volume.
Balance
Grasp the Volume knob and pull it outwards while rotating it left or right to
adjust the speaker left-right balance. The center balance point is indented for
easy location.
Fader
