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 automob ile chassis using a
ring terminal and a sheet metal screw.

5. Connect the ACC wire to the factory accessory or ignition wire, which

affect audio transmission to headphones.

NOTE: Your head unit must be compatible with the MZ7 TFT 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.

Menu Operation

While the monitor is turned on, press the POWER button to access the “MAIN
MENU” on the MZ7TFT screen. Touch a main menu selection to see the
corrresponding sub-menu.

• EXIT: To exit the menu from any level, touch the EXIT option on screen.

• PICTURE: Adjust the Brightness, Color, Contrast or Tint from -15 to +15.

• FUNCTION

• BLUE SCREEN (ON/OFF)

• VIDEO IMAGE (NORMAL/IMAGE (MIRROR))

• DISPLAY MODE ( NORMAL/FULL)

• AUTO DIMMER (ON/OFF): Useful for Daytime/Nighttime viewing

• DIMMER SCOPE (-30 to 0), -30 being more dim

• SOURCE

• SOURCE (AV1/AUX AV IN):

• IR AUDIO (A/B/OFF): If there is more than one (1) MZ7TFT in use

simultaneously, each headphone must be set to receive on a different

MZ7TFT

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 chann el 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.

• SCREEN ADJUST

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 th en plug the red, white and
yellow RCA connectors into your A/V device.
