AUTOMATIC
TUNING
MANUAL
TUNING
NOTE: To change the radio frequency by a single increment, press and
hold the TUNE +/– button until the frequency changes, then
immediately release.
TUNING RADIO STATIONS
The TUNE +/– buttons are momentarily pressed to scan radio
frequencies, until the next strong station is found. The audio is muted
and the displayed frequency changes during this automatic tuning.
Once the MC302 locks onto a strong station, it will stop scanning.
The TUNE +/– buttons are pressed and held, to perform manual
tuning of the radio. After about 1 second of holding a TUNE button,
the MC302 will go into the manual mode. The displayed frequency
changes and the audio plays at each frequency. The frequency
continues to change until the TUNE button is released. The manual tuning is used to
select a station that is not strong enough to be picked up by the automatic search, or
to scan through many frequencies without stopping on each strong station.
USING MEMORY PRESETS
Storing radio station frequencies
Change to the desired radio band
1(FM1, FM2, AM1 or AM2), using the
SOURCE button.
Tune the radio to the desired
2station.
Press and hold a preset button until
3the preset number is displayed.
Example: Save a radio station in band
FM2, preset 3.
Press the SOURCE button to
1change to FM2.
Tune the radio to the desired
2station.
Hold the 3 button until a 3 appears
3as the preset number.
Recalling radio station frequencies
Change to the desired radio band,
1using the SOURCE button.
Momentarily press the desired
2preset button.
Example: Recall the radio station saved
in band AM1, preset 2.
Press the SOURCE button to
1change to AM1.
Momentarily press the 2 button.

ADJUSTING THE SOUND
MENU buttons - Pressing both VOLUME buttons together enables the MENU mode.
The MENU mode operates differently when the power is off or on. When the power is
off, the MENU mode selects either INTERCOM VOLUME, SPEAKER VOLUME or
monitor enable functions. Pressing the two VOLUME buttons together, alternately
selectsbetweenthethreemodes. Theselectedfunction isindicatedonthe displayand
it may be adjusted by the VOLUME +/– buttons. When the power is on, the MENU
mode steps through the following functions MUSIC VOLUME, SPEAKER VOLUME,
BASS, TREB (Treble), LOUD (Loudness) and then back to MUSIC VOLUME. Again,
theselectedfunctionisindicatedonthedisplayand it may be adjusted by the VOLUME
+/– buttons.
SPEAKER VOLUME Sets the level of the master unit
speaker.
NOTE: Each room has its own volume control which can
be used to turn down the audio level for that room.
MUSIC VOLUME Sets the system level for the music
audio. Either a Remote Scan
speaker or a hand-held remote
control may also change this
volume.
INTERCOM VOLUME Sets the volume level for
communications. The intercom
volume is adjusted independent
of the music volume and
generally does not require
change from the initial setting.
NOTE: The music must be OFF before the INTERCOM VOLUME can be adjusted.
The MONITOR function enables or disables the room monitor
feature. This feature is turned either on, indicated by the '+', or
off, indicated by the '–'.
BASS and TREB are two tone control settings. These settings
are used to either boost or cut the appropriate frequencies to
optimize the music quality. The bar graph indicates a cut by
starting in the middle and displaying segments to the left, and
indicates a boost by displaying segments to the right.
The LOUD (loudness) function is turned either on, indicated by
the '+', or off, indicated by the '–'. This function boosts the bass
response at low volume levels.
6
NOTE: For best performance, the individual speaker volume controls
should be turned to maximum volume (fully clockwise) and then
the VOLUME UP/DOWN buttons adjusted for the proper listening
volume (this is really setting the maximum listening volume). The
individual speaker volume control can then be adjusted in rooms
that require less volume.
IMPORTANT: Donotsetthe "systemvolume"toahigh numberand then
adjust all individual speaker volume controls down to low
levels. This is very inefficient and may add distortion to
the system.
Hand Held RF
Remote Control
OPTIONAL HAND-HELD RF REMOTE CONTROL
PROGRAMMING - Upon initial power up of the MC302, the unit
must be programmed or taught the unique code that is
present in the REMOTE CONTROL TRANSMITTER.
The MC302 must be put into its test mode by
STEP 1 momentarily pressing the VOLUME + and
SOURCE buttons at the same time. The display
on the MC302 should show TEST.
Now press the TUNING UP button on the
STEP 2 REMOTE CONTROL TRANSMITTER until the
displayflashes SAVE twice. The MC302 has now
learned the TRANSMITTER.
If more than one transmitter is to be used with the
STEP 3 system, press a different button for each
TRANSMITTER to be programmed.
The test mode is exited by momentarily pressing
STEP 4 the VOLUME + and POWER buttons at the same
time.

when CD is selected as the
source.
OPERATION - Your HAND HELD REMOTE CONTROL is an RF (radio frequency)
device. This means that it will work anywhere in or around your house (you do not
have to be in the same room as the master). The system also has a unique code in the
transmitter that is learned by the MC302, virtually ensuring that no one else can
interfere with your system and you will not interfere with anyone else.
SOURCE button -Thisbuttonisusedtoselect
1the audio source (FM, AM, AUX or TAPE
inputs) which the MC302 will output to the
Music Speakers. Each time the SOURCE
button is momentarily pressed, the audio
source changes. The sequence is FM, AM,
AUX, TAPE, and back to FM.
TUNING UP/DOWN buttons - To go to the
2next presetstation, simply press the UP button
momentarily. The MC302 will tune in the next
station from the last stationed tuned.
3
VOLUME UP[ON]/DOWN[OFF] button - These
buttons are used to change the system music
volume. Pressing the VOLUME DOWN button reduces the volume. The MC302 will
turn off when the volume reaches zero. Pressing the VOLUME UP button turns the
MC302 ON if it is OFF.
