Wiring
1. Align the ridges on either end of the combined input cable (VIDEO IN,
AUDIO L, AUDIO R, REAR TS, GROUND and ACC) and connect the
cable to the male connector on the back of the MZ7TFT. The connector
will only fit when the notched areas are properly aligned.
2. Connect the REAR TS connector to the MZ7-TFT connector on the back
of your compatible head unit (if applicable).
NOTE: You can connect up to three monitors to your compatible head
unit using the Touch Screen Expansion Module (included). See “Touch
Screen Expansion Module” on page 4 for instructions.
3. Connect the AUDIO R, AUDIO L and VIDEO IN connectors to the Video
and Audio output (Headphone Multizone) cables on the back of your
compatible head unit or to another auxiliary device for which you would
like to output video.
4. Connect the black GROUND wire to the factory ground wire on your head
unit, or to a clean, unpainted metal part of the automobile chassis using a
ring terminal and a sheet metal screw.
5. Connect the ACC wire to the factory accessory or ignition wire, which
receives power when the key is turned on.

Operation
Power On/Off/Standby
The input allows voltage ranges from DC 10.8V to 16V, which includes the DC
12V car power supply.

screen capability for the IR remote repeater function to work.
After connecting the power, the monitor will be in standby mode. Press the
POWER button to turn the monitor on. Press and hold the POWER button to
return the unit to standby mode.

NOTE: Your head unit must be compatible with the MZ7TFT touch
screen capability for the Touch Screen function to work.
IR Interference
When used in or near direct sunlight, you may experience loud background
noise or a low audio signal. This is inherent in Infrared Ray communication
and does not mean there is a problem with the MZ7TFT itself.
If you use the MZ7TFT by a window with bright sunlight, draw the curtains/
blinds to shut out the direct sunlight, or use the MZ7TFT away from the
sunlight.

channel, and each MZ7TFT must be set to transmit on the same
channel as the headphone (i.e., left seat monitor/headphones set to
channel A and right seat monitor/headphones set to channel B). This
will prevent interference of audio by the IR signal being transmitted
from two monitors on the same channel. This is inherent in Infrared
Ray communication and does not mean there is a problem with the
MZ7TFT itself.
Selecting the Input Signal
The unit is provided with a AV-IN jack on the front of the monitor, as well as
AV1 inputs for your head unit or other device with composite video and line
level audio output.
When connecting the monitor to an alternate A/V device, you can plug an A/V
cable (Figure 5) into the AV-IN input jack, and then plug the red, white and
yellow RCA connectors into your A/V device.
