GENERAL FUNCTIONS
Power ON/OFF
To turn the unit ON, press the POWER button. The unit will resume the mode that was selected when it was last turned off.
To turn the unit off, press the POWER button again. Note that when the unit is turned OFF, the clock is displayed.
Controls
The Volume, Bass, Treble, Balance and Fader controls are selected electronically. The default selection is the Volume control. To select another control, press the SEL button repeatedly until the name of the control you require is displayed on the LCD. Each press cycles to the next control in sequence and the display shows the current setting for that control. If no button is pressed for 3 seconds, the display returns to normal and the control defaults back to the Volume control.
• Volume: To adjust the Volume, simply press the VOL or VOL buttons. 'VOL' will appear on the display along with a number indicating the current setting. Press VOL to increase the volume level or VOL to decrease the volume level. A level of 63 on the display indicates maximum volume.
• Bass: Press the SEL button repeatedly until ‘BAS’ is displayed. Press VOL to increase the Bass level or VOL to decrease the Bass level. A level of 0 on the display indicates a flat Bass response.
• Treble: Press the SEL button repeatedly until ‘TRE’ is displayed. Press VOL to increase the Treble or VOL to decrease the Treble. A level of 0 on the display indicates a flat Treble response.
• Balance: Press the SEL button repeatedly until ‘BL’ is displayed. Press VOL to increase the volume in the right speakers. 'BL R' is displayed along with a number representing the volume level of that channel. Press VOL to increase the volume in the left speakers ('BL L' is displayed).
To set the Balance to the center position, press VOL or VOL to reduce the front or rear setting until ‘BL C0’ is displayed, indicating the centre position.
• Fader: Press the SEL button repeatedly until ‘FA’ is displayed.
Press VOL
to fade the sound toward the Front speakers (and reduce the volume in the Rear speakers). ‘FA F’ is displayed along with a number to show the level of the Rear speaker setting.
Press VOL to fade the sound to the Rear speakers (and reduce the volume in the front speakers). ‘FA R’ is displayed along with a number to show the level of the Rear speaker setting.

OPERATION
MST70 Owner’s Manual Page 11 the front or rear setting until ‘FA C0’ is displayed, indicating the centre position. Liquid Crystal Display (LCD) The LCD indicates the station frequency and the selected band along with any other selected functions. The display is permanently back lit for low light viewing. Loudness LOU Press the LOU button to increase the bass level at low volume settings. This feature compensates for the ear's inability to pick up low frequency sounds when the volume is turned down. When the LOU button is pressed, 'LOUD' appears on the display. Mute MUT Press the MUT button to temporarily silence the sound in the speakers. 'MUTE' flashes on the display. You can use this feature when talking on your marine radio. Press MUT again (or the VOL or VOL buttons) to restore the sound. RADIO Band BND The MST70 has 5 selectable frequency bands labelled FM1, FM2, FM3, MW1 and MW2. Bands FM1 - FM3 are identical and cover the FM band from 87.5 MHz to 107.9 MHz. The MW bands cover the AM frequencies from 530 kHz to 1710 kHz. Up to 6 channels in each band can be stored in memory, making 18 FM and 12 AM channels available. The 3 FM and 2 AM bands allow stations from different areas to be stored and kept seperate. e.g. Hometown FM stations can be stored using FM1. When traveling to new areas, new local stations can be located and stored using FM2 or FM3, leaving the hometown stations in FM1 for when you return home. To change bands, press BND. Each press will advance to the next band i.e. FM1 - FM2 - FM3 - AM1 - AM2 - etc. Tuning Manual Seek ( ) To manually change the frequency in steps, press the TUN or button repeatedly. Automatic Seek To automatically tune the radio to a station, press and hold the TUN or buttons for more than 1 second. The radio will automatically seek through the selected band until a station is found, tuning then stops on that station. To tune
Page 12 Owner’s Manual MST70 to the next station, press and hold the TUN or buttons again. Manual Station Preset To manually store stations in the station memories: 1. Select the required station frequency using the TUN or buttons. 2. When the station is tuned, press and hold the required station preset number 1 - 6 for more than 2 seconds. The selected station will be stored in that preset memory and the preset number will be displayed. To recall station memories, briefly press the required station preset number 1 - 6. Auto Memory Store AMS Use the Auto Memory Store AMS function to automatically locate stations and store them in memory. In FM mode, stations are stored in order of signal strength with the strongest signals being stored first. In AM mode, stations are stored in the sequence in which they are found. To automatically store stations in memory, press and hold the AMS button for more than 1 second. 'ATP' will be displayed when Auto Memory Store is functioning. • In FM mode, the radio will begin tuning upwards through the entire selected band (FM1, FM2 or FM3), starting at the currently selected frequency and returning to that frequency when finished. The memories for that band will then contain the six strongest FM stations in your area. • In the AM mode the radio will begin tuning upwards (from the currently selected frequency) and will store the first six stations found. Tuning will then stop. Note: If the AM stations you wish to store were not included because the memories were filled up by other unwanted stations, select a frequency to start from that which is just below the stations you wish to store (using the TUN or buttons, then press the AMS button. Stations will be then located and stored starting from the selected frequency. Alternatively, if the memories were filled by weak unwanted stations, select the Local mode (by pressing the LOC button) so that only the stronger local stations are located and stored - see Local/Distant operation described below. Mono/Stereo M/S The M/S button can be used to select either Mono or Stereo reception when in FM mode. • Mono: Selecting Mono improves reception when FM signals are weak or noisy, by disabling stereo detection. When selected, there is no indication on the display. Note: MONO selection is only available on the FM, FM2 or FM3 bands. • Stereo: Select stereo for normal stereo listening on the FM radio bands. When stereo is selected and a stereo signal is being received, ST is displayed.
MST70 Owner’s Manual Page 13 Local/Distant LOC Press the LOC button to reduce the radio's sensitivity to weaker, distant signals. 'LOC' is displayed. This is particularly useful when seeking or auto-storing local stations as it reduces the weaker signals so that only the stronger local signals are found and stored. To intentionally receive weak or distant signals, press the LOC button again to return to Distant mode. Clock DSP To display the clock on the LCD, press the DSP (display) button. To return to the previous mode, press the DSP button again. To set the clock: 1. Press the DSP button to display the clock. 2. Now press and hold the DPS button while pressing the button to adjust the hours or the button to adjust the minutes. RESET Your MST70's functions are controlled by a microprocessor. If after installation, you find that some of the functions do not appear to work correctly, you can reset the microprocessor to restore the radio to its default settings. Note that after the reset, you will need to reprogram your station memories. The reset button is located beneath the removable front panel. To reset the radio: 1. Press the release button to remove the front panel (see 'Detachable Front Panel' on page 3). 2. Locate the reset switch using the diagram below. 3. Press the switch using a ball point pen or similar.

To change the play direction manually, press > simultaneously. The direction indicator on the display will change to indicate the new direction. To stop the tape and eject the cassette, press the eject button ^.
