ABOUT YOUR SYSTEM
Your new Model MC702 is a state of the art stereo music and intercom system that provides music and room to room communication throughout your house. An optional door chime can be integrated into the system to provide door communication with automatic muting. The MC702 contains a digital clock with backup power source that maintains the correct time for up to 3 hours without power and never needs replacing.
The innovative transflective LCD display and power-conserving back light can be read in any lighting condition from direct sunlight to complete darkness. The unit provides music for up to 15 rooms with plenty of power. The MC702 has a digital phase lock loop tuner with 8 AM and 8 FM station presets. It also has two external source inputs (AUX IN and TAPE IN) and one line output (TAPE OUT) that can be used with M&S's built-in cassette tape and/or CD player, as well as your TV or other music sources. The MC702 enables communication between up to 15 rooms and the master location plus up to 4 door entry locations.
The MC702 can turn itself ON and OFF at preset times like an alarm clock or sleep-to-music device. As a home security device, it can be programmed to play talk radio when the house is vacant. The MC702 was designed to be as user­friendly as possible the display tells you how to set the time and alarm functions. It also shows when and how the intercom function is being used. It has a built-in door release which can be used to open a door or gate from the master unit or from any indoor remote room station.
The MC702 has an optional hand-held RF REMOTE CONTROL which allows you to turn the radio on or off, scan radio stations up or down, change sources, and change the volume up or down from ANYWHERE in or around the house.
The MC702 allows you to monitor any room (including the master unit location) to let you know when a baby is crying or when an elderly person needs help.
Like all M&S products, the MC702 is designed to make your home atmosphere more enjoyable. M&S is committed to producing high quality products for your home. If you have any questions about the operation of your system, please call us at (800) 366-9422.

SETUP
Note: The MC702 remains in the set mode for 25 seconds with no activity
(no buttons being pressed) after which the unit automatically returns to the normal mode of operation. The TIME SET button must be pressed again to return to the set mode.
SETTING THE TIME
When the Time/Auto Set button is pressed momentarily, the display will show SET TIME and the current time will be displayed with the hours flashing. The UP and DOWN buttons (either TUNING UP and DOWN or VOLUME UP and DOWN) can then be used to increment or decrement the current time hours. Pressing the UP button (or DOWN button) momentarily will increment (or decrement) the hours by one each time the key is pressed. Holding the UP button (or DOWN button) depressed will rapidly increment (or decrement) the hours until the button is released. The time display also includes the AM or PM indicator that is changed by scrolling the hours past 12:00.
Once the current hours have been set correctly, momentarily press the TIME/AUTO SET button again. The display will show SET TIME and the current time will be shown with the minutes flashing. The UP and DOWN buttons can be used as described previously to increment or decrement the current time minutes.
Once the current minutes have been set correctly, momentarily press the TIME/AUTO SET button again to return to the normal mode or let the MC702 automatically return to the normal mode if no buttons are pressed for 25 seconds.
S
ETTING AUTOMATIC ON/OFF TIME
To set the AUTO on and off times, the TIME/AUTO SET button must be momentarily pressed three times
6
without changing the current time. After pressing the TIME/AUTO SET button for the third time, the display will show SET AUTO ON TIME and the auto on time will be displayed with the hours flashing. The UP and DOWN buttons can be used as previously described to increment or decrement the auto on time hours.
7
Once the AUTO ON TIME hours has been set correctly, momentarily press the TIME SET button again. The display will show SET AUTO ON TIME and the AUTO ON TIME will be displayed with the minutes flashing. The UP and DOWN buttons can be used as previously described to increment or decrement the AUTO ON TIME minutes.
Once the AUTO ON TIME minutes has been set correctly, momentarily press the button again. The display will show SET AUTO OFF TIME and the AUTO OFF TIME will be displayed with the hours flashing. The UP and DOWN buttons can be used as previously described to increment or decrement the AUTO OFF TIME hours.
Once the AUTO OFF TIME hours has been set correctly, momentarily press the TIME SET again. The display will show SET AUTO OFF TIME and the AUTO OFF TIME will be displayed with the minutes flashing. The UP and DOWN buttons can be used as described previously to increment or decrement the AUTO OFF TIME minutes.
S
ETTING THE AUTO ON VOLUME LEVEL
When the Auto function is turned on, the MC702 will turn itself on automatically when the current time reaches the Automatic ON TIME and will then turn itself OFF when the current time reaches the Automatic OFF TIME. When the MC702 automatically turns itself ON it will always turn on at the same volume level. This "AUTO ON VOLUME LEVEL" has a default of 12 but it can be changed following these simple steps:
ì Turn on the MC702 by momentarily depressing the POWER button (unless the
radio is already on).
í Momentarily press the VOLUME UP and AUTO buttons, at the same time, and
then release. The display will show the letter 'A' for AUTO ON volume followed by the current music volume setting.
î Depress the VOLUME UP or VOLUME DOWN buttons to set the desired
music volume level. (1-32).
8
NOTE: The MC702's AUTO ON volume is defaulted to the last volume setting
when the music was last turned off. Therefore, it is recommended that a new fixed auto volume setting be set since the MCTX wireless remote control transmitter, effectively, turns off the radio when the volume is turned down completely. If the music is turned off using the MCTX wireless transmitter the music will AUTO ON at a volume level of 1.
ï When you have the volume set to your desired level wait for 9 seconds. The
display will revert to the time display.

EMOTE INTERCOM STATION SELECTION
These switches are used to control the operation of the room station in each corresponding room. The MASTER INTERCOM switch controls the master room station. ROOM SELECTOR switches 1 through 9 control the corresponding remote room stations. The PATIO SELECTOR switch controls patio room station(s).
There are four positions for each of these switches:
INTERCOM- A room station with its switch set in the
INTERCOM position will only hear intercom (excluding monitor) and the chime.
RAD/INT - A room station with its switch set in the ON
position will hear intercom communications, music and chime.
OFF - A room station with its switch set in the OFF position
will not hear anything, but can still talk to other room stations and the door.
MONITOR A room station with its switch set in the MONITOR
position will not hear any intercom communications, but the room station will be used as a microphone. Any sounds that this microphone picks up will be heard from any room station that is in the ON position. The MONITOR position can be used to listen to (monitor) a baby's or elderly person's room.
Your MC702 may be equipped with either a 3-note or 8-note Door Chime. This optional chime always mutes the radio and rings through the master speaker when the doorbell button is pressed. It also rings through all the room stations that are turned on. However, the music speakers mute while the chime is broadcast through the room stations and the master unit.
S
ETTING THE INTERCOM LEVEL
The INTERCOM LEVEL adjust the gain of the entire intercom system. The INTERCOM LEVEL is generally set by the installer upon initial installation to match your home's acoustics and should not require further adjustment. However, if you find the system's intercom gain is too high or too low, follow the procedure below to reestablish the correct intercom gain setting.
ì Turn all room station volume controls to maximum (fully-clockwise). Turn the
master speaker volume to maximum (fully-clockwise). Set all PRIVACY switches to the OFF or out position (N75/N78 only).
10
NOTE: Your MC702 system is designed for high intercom gain and very low
noise simultaneously. When monitoring room stations, it is not necessary to increase the intercom level in an effort to hear 'something'. Doing so will unnecessarily increase any background noise, such as air conditioning systems and other appliances built-in to your home. If you are monitoring a baby's room, for example, no noise will be heard until the baby cries or makes a noises at which time you will hear with ample volume.
Steady SAVE (Release

SAVE
í Depress and hold ROOM TALK at the master location while speaking. î Adjust the INTERCOM LEVEL until good clear audio is heard at the remote
stations without hearing acoustic feedback (squeal). This initial setting should result in audio that is likely to be as loud as you would normally need. This setting should not be readjusted. The volume controls at the individual room stations can be adjusted as desired for that room.
S
ETTING UP THE WIRELESS REMOTE CONTROL
PROGRAMMING - Upon initial
power up of the MC702 or upon applying power after the unit loses its memory (power outages greater than 2 hours), the unit must be programmed or taught the unique code that is present in the REMOTE CONTROL TRANSMITTER. To do this, the MC702 must be put into its test mode by momentarily pressing the VOLUME UP and SOURCE buttons at the same time on the MC702. The display on the MC702 should show TEST.
While the MC702 is in the test mode, press and hold the TUNING UP button on the REMOTE CONTROL TRANSMITTER. The display on the MC702 will flash between TEST and SAVE. When the display shows SAVE without flashing, release the button on the transmitter. The MC702 has now learned the TRANSMITTER. Momentarily press both VOLUME UP and POWER buttons at the same time to restore the MC702 to normal operating mode.
If more than one transmitter is to be used with the system, the second, third, and fourth transmitters must be learned by pressing the TUNING DOWN, VOL UP, and VOL DOWN on

OPERATING THE TUNER
To listen to broadcast stations, press the POWER button. Notice the display will change from the time to station frequency. Pressing the SOURCE select button will allow you to change from FM, AM, TAPE and AUX respectively. The SOURCE button is available on the MCTX wireless remote control transmitter.
AUTO SCAN When any AM or FM band is chosen, momentarily pressing the TUNING UP and TUNING DOWN buttons will change the tuned station frequency to the next local station. The audio will be muted and the display will show radio station frequencies increasing or decreasing as it scans. When the next local radio station is detected, audio will again be heard.
MANUAL SCAN Pressing and holding either the TUNING UP or TUNING DOWN button will cause the tuner to scan each successive frequencies one at a time whether a radio station is broadcasting on that frequency or not. You will also be able to hear the reception at these frequencies as they are scanned. When the desired radio station is tuned, release the TUNING UP or TUNING DOWN button to stop the manual scan function. Manual scanning is useful for reception of distant stations that would not otherwise be tuned with the auto scan feature. The MC702 automatically switches from stereo to mono to allow greater sensitivity for a distant radio station. NOTE: To scan upward or downward by just one frequency, the
TUNING UP/DOWN button should be depressed until the frequency changes--then immediately released.

PERATING A TAPE OR CD PLAYER
The MC702 features two source inputs to connect a variety of built-in and external music sources such as Laser disc players, CD players and tape players. The different sources connected to the TAPE and AUXILIARY inputs are selectable by pressing the SOURCE select button once the POWER is turned on. Momentarily depressing the SOURCE button changes the music source from FM, AM, AUX and TAPE inputs, respectively. The SOURCE button on the MCTX wireless remote control performs the same function as the SOURCE select button on the MC702. NOTE: The SOURCE button is only active when the power is on. NOTE: IF the MC702 is installed with the MCD6 multidisc CD changer, the TUNING UP/DOWN buttons on the MCTX wireless remote control transmitter will operate the track selection when AUX mode is selected on the MC702.
A
DJUSTING MUSIC VOLUME
15
CAUTION: Take care not to overdrive the amplifier by using excessive
system volume to overcome the low volume settings on the music speakers. Doing so will result in distorted audio and may cause amplifier failure!
There are two ways to adjust music volume. The MC702 system volume control adjusts the music volume for all music speakers in the house and shows the volume setting on the display. (1 = lowest
volume and 32 = highest volume) Depressing and
holding the VOLUME UP or VOLUME DOWN button steadily increases or decreases, respectively, the system volume. Momentarily depressing the VOLUME UP or VOLUME DOWN increases or decreases, respectively, the system volume by one level. Each speaker in the house has a volume control to adjust the output at the speaker itself. Normally, the individual speaker volume controls are set to maximum or near maximum settings.

INTERCOM OPERATION
ROOM TALK function (all call)
C
OMMUNICATING WITH OTHER ROOMS
The MC702 system with it's N75, N75RS, and NRC75 series speakers are designed for whole house communication and ease of use. To talk to the room station depress the ROOM TALK button while speaking. To hear the response depress the ROOM LISTEN button. It is not necessary for the called party to press ROOM TALK to reply. Therefore, this type of hands-free communication is beneficial when communicating with someone who is unable to reach the controls of room station to reply. If you are receiving a call from someone else, and are at a non-RS room station that has the PRIVACY feature enabled, you must either turn off the PRIVACY feature or press ROOM TALK to respond. When performing a ROOM TALK function, audio will be heard only at the stations that are turned on at the master and have their volume controls set above the minimum (counter­clockwise) setting. Stations that are set to the OFF or MONITOR position at the master will not hear the ROOM TALK call nor will they be heard in the ROOM LISTEN mode.

ONITORING OTHER ROOMS
Room station monitoring is useful for constant monitoring of small children and those requiring special care. Any station in which you wish to monitor should be set to the MONITOR position on the room switch panel. The result of the combined monitored stations will be broadcast to any station set to ON at the room switch panel. Non-RS room stations that have the PRIVACY feature enabled cannot be monitored regardless of the room switch setting at the room switch panel. The MC702 is designed to prevent the door chime from ringing at stations set to the MONITOR position at the room switch panel. This will prevent disturbing the occupants of the monitored rooms.
C
OMMUNICATING WITH DOOR LOCATIONS
The MC702 features two way intercom to the door locations. With the MC702 you need not risk unwanted intrusion by opening the door to respond to the door bell. To communicate with the visitor, depress both ROOM TALK and ROOM LISTEN buttons and speak. To hear the response from the visitor, simply release BOTH buttons. This will automatically switch the system to DOOR LISTEN mode. Pressing both ROOM TALK and ROOM LISTEN again allows you to again talk to the visitor. The DOOR LISTEN function will automatically time out in about 20 seconds or when you momentarily depress ROOM LISTEN or ROOM LISTEN by itself.
