SOURCE on the unit is pressed to activate the unit first.
Tip
See "Replacing the lithium battery" for details on how to replace the batteries (page 44).

Installation angle
The unit should be installed within an
angle of 25 degrees from horizontal. If
this angle is exceeded, the monitor may
not open up or retract properly.
Note
Keep the units and connection cables
apart.
The Media Center main unit and the
connection box 1 should not be in close
proximity.

Installing the Main Unit
Before installation
This unit is designed to be completely safe, but if not installed
correctly, it can cause accidents. Be sure to verify the following
points before installation.
Install the main unit to the in-dash location, and the connection
box under the navigator's seat, etc.
· If the monitor in the opened position is close to a air-
conditioning outlet, the outlet should be closed.
· Install the unit so that the monitor when opened up will not
block access to the hazard switch or other important controls.
·Do not install the unit (monitor) in locations which may be
subject to excessively low or high temperatures. (Otherwise the
unit may be deformed and the LCD may be damaged.)
Exposure to direct sunlight can also lead to high temperatures
and should be avoided.
Selecting the installation location
1 Set the ignition key to OFF or remove it.
2 Place the units in their intended mounting
locations to check the cable length and monitor
installation conditions.
Frequency select switch (E model)
The AM (FM) tuning interval is factory-set to the 9 k (50 k)
position. If the frequency allocation system of your country is
based on 10 kHz (200 kHz) interval, set the switch on the bottom
of the unit to the 10 k (200 k) position before making connections.

Installation procedure precautions
· Perform the installation carefully. Dropping the unit or
otherwise subjecting it to strong impact or force may deform
the chassis, resulting in failure of the monitor loading
mechanism or other defects.

·To allow for proper opening and closing of the monitor, there
must be a clearance of at least 147 mm between the closest
position of the gear shift lever and the mounting surface for the
unit.
· In some cases, the gear shift lever may touch the monitor when
moved to a certain position. Make sure that there is no
obstruction to driving operations.
·When installing this unit together with other car audio
equipment (single DIN slot size) in a stacked configuration,
install the Media Center main unit on top.

At least 147 mm
(5 7/8 in.) from
mounting surface
Note
If the installation dimensions shown at
right are not observed, the monitor may
not open up smoothly. If this happens,
check the installation once more and
modify the cluster panel where the
dimension requirements are not met. For
some car models, a separately available
mounting kit may be required.
(For details, please consult your dealer.)
