Before installation
·Install the antennas only on the rear window.
·Keep the antennas away from other antennas on the car,
such as for CB or amateur radio, cell phone, etc. If
installed too close, antennas may cause mutual
interference.
·On days with high humidity (rain, fog, etc.), make sure
that the installation surface is fully dry before beginning
the installation. Wet conditions will reduce the adhesive
strength and may cause the antennas to fall off.
·If the installation surface is cold, warm it up first with
the car heater, rear window defogger, a hair dryer or
similar. This will increase adhesive strength.
Before installing the TV antennas (5)
Select a fairly flat section of the rear window for
installation. If the glass is strongly curved, the antenna
may come loose. Wipe the intended installation area with
a dry cloth to remove any moisture or dust.
In cars which have a lining (pillar) near the rear window,
remove the lining to gain access to the metal for use as
ground.
It is not necessary to scratch off the paint from the
metal surface.
Check mounting position for TV antennas (6-1)
Verify the left and right antenna positions. Pull the
antenna rods straight out, and provisionally fasten them
with tape or similar. Take care that the rods from the left
and right antennas do not overlap or touch each other.
In some cars, it may not be possible to extend the long rod
fully. In such a case, bend the rod in a smooth curve.
Notes
·When installing the antennas, try to avoid the defogger
wiring.
·Do not touch the adhesive surface or reposition the
antenna, as this will decrease adhesive strength.
·The short antenna rod should be on top. If the long rod
is on top, sufficient sensitivity may not be achieved.
Attach ground plate 6 to antenna body (6-2)
Be sure to mount the ground plate. Otherwise antenna
sensitivity will be reduced.
At this stage, the support clamper should only be
snapped onto the antenna but not yet glued in place.
After installation
·For 24 hours after installation, do not subject the
antennas to rain, splashes of water, or strong force.
·Before starting to drive, make sure that the antennas are
securely fastened.
·Also after starting to use the system, check the antennas
from time to time.
·Do not wipe the antenna body, rods, or cables with
alcohol, benzine, solvents, gasoline, wax, or similar, as
this can cause deformation or other damage.
·Reception may be impaired in the following locations:
1. Between tall buildings
2. In the vicinity of high voltage power lines
3. In the vicinity of flying aircraft
4. In the vicinity of electric trains and streetcars
5. In mountainous areas or areas far removed from broadcast
transmitters
6. In tunnels
7. Very close to commercial or amateur radio transmitters

Peel off covering paper on bottom of antenna and
stick antenna onto mounting surface ( 6-3)
Stick the antenna onto the mounting surface, with the
rods extended straight.
Tip
Before attaching the antennas, make sure that the
installation surface is clean.
TV antenna installation precautions
·Mount the antennas only on the inside of the rear
window.
·Do not install the antennas in locations which may
obstruct the driver's view.
·Be sure to connect the power supply lead to the ACC
circuit.
·Keep the TV antenna cables as far away as possible from
wiring for an external amplifier and rear speakers.
Route TV antenna cables (7-1)
Refer to the wiring diagram below.
Notes
·Pull out the TV antenna rods as much as possible, but
take care that the rods do not cross or touch each other.
·In some cars, the shape or size of the rear window or the
opening of the rear gate may prevent installation of the
antennas.
For details, please consult your dealer.
Connect TV antenna cables to TV tuner unit
(7-2)
Dealing with excessive TV antenna cable
length (8)
If you coil the antenna cable and place it in the vicinity of
the TV tuner unit, noise may occur. Do not coil the cable,
and keep it as far as possible from the TV tuner unit.
Wiring (9)
If cables become tangled with the gear shift lever or other
controls, there is a severe risk of accident.
When using the Media Center main unit, keep the RCA
interconnects as far away from the antenna cables as
possible. Otherwise noise may appear on the TV picture.
Precautions
·This unit is designed for negative ground 12 V DC systems
only.
·Do not get the wires under a screw, or caught in moving
parts (e.g. seat railing).
·Before making connections, turn the car ignition off to avoid
short circuits.
·Connect the yellow and red power input leads only after all
other leads have been connected.
·Run all ground wires to a common ground point.
·Be sure to insulate any loose unconnected wires with
electrical tape for safety.
Notes on the power supply cord (yellow)
·When connecting this unit in combination with other stereo
components, the connected car circuit's rating must be
higher than the sum of each component's fuse.
·When no car circuits are rated high enough, connect the unit
directly to the battery.
Parts list (1)
·The numbers in the list are keyed to those in the
instructions.
· Use 8 and 9 to organize cords.
Connection Example (2)
Installing the TV Tuner Unit (3)
Notes
·Ensure that the mounting surface is clean.
·Do not install the TV tuner unit
-in locations subject to high temperatures
-in locations subject to direct sunlight, warm air from heater
outlets, or other locations that can get hot.
·When attaching the hook-and-loop fastener to the
bottom of the TV tuner unit, do not cover the model
name plate in the center.
Keep the units and connection cables apart.
The Media Center main unit, TV tuner unit, and RCA
interconnects should not be in close proximity. Otherwise
noise interference may affect the TV picture.

EQUIPMENT USED
For electrical adjustment, the following measuring instruments are
used:
· TV Tuner Unit (XT-63V)
· Media Center Main Unit (XAV-7W)
· Connection Box (XA-114)
· TV SSG
· Oscilloscope
· Synchroscope
· Digital Voltmeter
·Frequency Counter
·Level Meter
·Regulated Power Supply
SETUP FOR ADJUSTMENT
The TV tuner adjustment uses, as an adjusting signal, the video
signal generated from the TV SSG.
Perform adjustment after making sure that this signal satisfies the
specification.

PIF ADJUSTMENT (45.75MHz)
Connection:
Adjusting Method:
1. Connect the TV SSG to the TP109 (IF) on the HIDE board.
2. Connect the oscilloscope to the TP132 (PIF) on the HIDE
board.
3. Connect the TP42 (RF2) and TP60 (GND) on the HIDE board
with a capacitor to place the TV tuner unit (TV100) in the
non-signal state.
4. Connect the regulated power supply to the TP142 (2AGC) and
apply +5.5 V.
5. Adjust the receiving channel of the set to an idle channel where
there is no broadcasting station.
6. Adjust the T106 on the HIDE board so that the DC level of the
waveform on the oscilloscope becomes the lowest.
Note: After the PIF adjustment, be sure to perform the following.
