Standard Horizon Receiver MST660 Operating Instructions

							MST660                                                           OwnerÕs Manual                                                           Page 9
Referring to the wiring diagram:
1.Connect the Red wire labelled ÔBATTERY B+Õdirectly to the positive
terminal of the vesselÕs battery, or to a point which has +12 Volts available
at all times. This lead maintains the memories within the MST660 and is
the main power source for the unit.
2.Connect the Orange wire labelled ÔPOWER B+Õto the vesselÕs +12V
supply via an appropriate isolating switch or circuit breaker. This lead turns
the radio ON and OFF. Alternatively, this wire can be connected directly to
the batteryÕs positive terminal and the MST660 switched ON and OFF
using itÕs own controls.
3.Connect the Black lead labelled ÔGROUNDÕ to the batteryÕs negative
terminal or to the common negative bus in the electrical system.
Important:Your MST660 is able to maintain itÕs memories when it is switched
off by drawing power directly from your battery via the Red ÔBATTERY B+Õ
lead. Although the memory backup current is very small (about 4 mA) it may
eventually discharge your battery if left connected indefinitely. The time taken
to completely discharge your battery could vary depending on itÕs Amp-hour
rating and condition.
If you do not run your boatÕs motor regularly or your battery is not kept
charged between outings (e.g. Solar or wind charger), we recommend you
disconnect the Red lead each time you secure your boat. This is easily done
by connecting the Red ÔBattery B+Õ lead via a Master switch which can be
switched off after each outing.

Speaker Connections
When connecting the speakers, observe the correct polarity as shown in the
diagram. Incorrect polarity will result in a reduction of Bass response and stereo
effect. The use of speakers with an impedance of less that 4 Ohms is not
recommended, as they will cause excessive loading of the MST660Õs output
circuit. 
Caution:The MST660 is a four speaker system that requires 2 separate wires
for each speaker.
¥DO NOT connect the negative (-ve)  terminals of the speaker wires
together or ground them to any part of the negative electrical Bus.
¥DO NOTshort the +ve and Ðve speaker wires together. 
Damage caused by the above will not be covered under warranty.
Connect all four speakers as shown in the diagram. Adjust the Fader control
for the required front/rear balance. If you wish to connect only two speakers,
connect these to the Rear speaker wires. The remaining speaker wires should
be insulated to ensure they cannot short circuit together or to ground. If using
only two speakers, adjust the Fader control to the Rear speakers.

Antenna Connections
Connect an AM/FM marine antenna to the antenna socket, which extends
from the rear of the MST660.
RESET BUTTON
When the installation is complete, remove the front panel and press the Reset
button using a ball point pen or similar (see PRECAUTIONS on page 2). This
will ensure the MST660 is ready to be switched on for the first time. If at any
time the controls do not seem to work (after replacing the vessels battery for
example), press the Resetbutton to reset the microcomputer inside the
MST660.
FUSE REPLACEMENT
If any of the fuses blow, replace them with the following:
Red ÔBattery +Õlead:  10 Amp, 3AG.
Orange ÔPower B+Õlead:  1 Amp, 3AG.

ÔMUTEÕ appears on the display. You can use this feature when making or
receiving phone calls or talking on your marine radio. Press  MUTagain 
(or the volume  +or  Ðbuttons) to restore the sound to normal levels.
Note that the sound will not be completely silenced, but will be reduced to
a low level.
RADIO
When the unit is turned on, it will automatically return to the mode it was in
when switched off. If the radio was selected, the last used radio station
memory will be selected automatically. If the CD mode was selected, press
BNDto change to the radio mode
Selecting the Memory Band
There are five memory bands available - three FM and two AM. Each band has
six station memories giving a total of 18 FM memories and 12 AM memories. If
you have programmed all six memories in one band, you can select the next
band and continue programming more stations. If you often travel away from
your local area, you can store your local stations in one band and the stations
for the area you are visiting, in another band. 
To select another band press the BNDbutton. Each press selects FMI, FMII,
FMIII, AMI or AMII in sequence.
Using the M/S Button
The M/Sbutton can be used to select either Mono reception or Stereo
reception.
¥Mono:Selecting Mono improves reception when FM signals are weak or
noisy, by disabling stereo detection. When selected, ÔMONÕis displayed.
Note: MONO selection is only available on the FMI, FMII or FMIII bands.
¥Stereo:Select stereo for normal stereo listening on the FM radio bands.
When stereo is selected, asymbol is displayed
Manual Tuning
To tune the radio manually, press the     or     buttons. Press      to step
downward in frequency and        to step upward in frequency. 
Automatic Tuning (SEEK)

Programming the Pre-set Station Memories
Manual Programming
To manually program a station memory:
1.Select the required Band (FMI, FMII, FMIII, AMI or AMII).
2.Press the       or        buttons to select the required station.
3.Press and hold one of the six pre-set station memory buttons for 1 second.
That pre-set memory number will appear in the display indicating that the
memory is now programmed. e.g. if memory button  4 was pressed, Ô4Õ
will appear in the display. If the selected memory button already contains a
station,it will be replaced by the new station.
Repeat the above steps to program other pre-set station memories.
Automatic Programming
1.Select the required Band (FMI, FMII, FMIII, AMI or AMII).
2.Press and hold
the AMSbutton for more than 2 seconds. The radio will
begin searching the selected band for radio stations. As each station is
located, it is stored into the next available pre-set station memory. The
new stations will replace any stations previously stored in that band. Once
all memories in that band have been programmed, the Automatic Memory
scan will stop and the radio will play the station in pre-set memory 1.
Scanning Pre-Set Station Memories
To scan through the pre-set station memories, briefly press the AMSbutton.
The radio will step through the pre-set station memories in the selected band,
pausing for about 10 seconds on each station. If you hear a station you like,
briefly press AMSagain (or the corresponding station memory button). The
pre-set memory scan will be cancelled and the radio will remain on that
station.
Selecting Pre-Set Station Memories
To manually select a pre-set station memory, briefly press the desired station
memory button 1 - 6. The radio will jump straight to that station and the
memory number will appear on the display. 
CD PLAYER
Caution: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.
Important:Because of the wide dynamic range offered by CD systems, the
difference in volume level between very soft sounds and very loud sounds can
be quite high. For this reason we recommend that you avoid turning the

mechanism will automatically draw the CD into the player and track 1 will
begin playing (indicated by ÔT - 1Õon the display).
A disc symbol is displayed on the left of the LCD whenever there is a CD in the
player. The symbol will simulate rotation whenever the CD is playing.
The MST660 will not allow you to insert a second CD while there is already
one in the player. If you find you are unable to insert a CD, check to see if the
disc symbol is displayed. If so, you will need to eject the current CD first.
When playing CDÕs, the Volume, Bass, Treble, Balance and Fader controls are
adjusted in the same manner described previously.
