Installation DIN front mount installation

Before installing your new
CD Receiver, please review the items
below carefully.

Choose a mounting location where the
unit will not distract or otherwise
interfere with the driver’s ability to
control the vehicle.

Before final installation, temporarily
connect the wiring according to the
diagram near the end of this manual,
check it to ensure that it has been
connected properly, and test the unit
to make sure it is working correctly.

Use only the installation parts and
hardware provided with the unit to
ensure proper installation. Using other
parts can cause malfunction and
possible damage to your CD
receiver.

If installation requires drilling holes or
other modifications to the vehicle,
consult with your nearest dealer or
professional car audio installer.

Do not install this unit at an angle in
excess of 30º from horizontal, as it
may affect performance.

Avoid installing the unit in a location
which is subject to high temperatures,
direct sunlight, hot air from such
sources as heaters or exhaust lines,
or where it will be subject to contact
with dust, dirt, moisture or excessive
vibration.

For details about installing the head
unit, read the instructions below
and refer to the diagrams for further
clarification.

Insert and tighten the “headless”
support screw into the back of the
head unit where shown.

Insert the mounting case for the head
unit into the dashboard. Inspect the
dashboard material to determine its
approximate thickness. Select the
appropriate support tabs and bend
them outward to secure the bracket
in place (Figure 1).

Bend the backstrap to conform to the
mounting case and the dashboard
surface to which you plan to secure
the backstrap (Figure 2). Slide one of
the utility holes on the backstrap onto
the support screw and fasten it with
the spring washer and nut provided.

Using the 5 x 25mm screw and the
plain washer, secure the backstrap to
the dashboard surface as shown in
the diagram. Tighten secure, and
check the overall mounting to be sure
it is safe and will not release in an
emergency stop or other sudden
movement of the vehicle.

Be careful when handling
the front panel!

1. Do not drop front panel.

2. When detaching or reinstalling, do
not put pressure on the display.

3. Do not touch the contacts on the
panel or the main unit body – doing so
may result in poor electrical contact.

4. Dirt or foreign substances can be
removed with a clean, dry cloth.

5. Do not expose the panel to high
temperaturees or direct sunlight.

6. Do not permit volatile agents or
solvents to contact the front panel.

7. Do not attempt to disassemble the
front panel.

Detaching the front panel

Press the RELEASE button to release
the panel from the right side of the
head unit (Figure 5).

Grasp the right side of the panel and

Removing the head unit

Figure 9 Pull out to remove bezel

Should you need to remove the head
unit, first remove and store the front
panel as described on the preceding
page.

After you have removed the front
panel, insert your fingers into the
groove along the right side or the left
side of the frame (not both!) and pull
out to remove the bezel (Figure 9).

Then, insert the levers supplied with
the head unit into the grooves on both
sides of the unit as shown in the
drawing until you feel a “click.” You
can now use the levers to pull the unit
from the dashboard (Figure 10).

Figure 10 Insert levers until “click” occurs, then use
levels to pull out head unit.

NOTE: If the panel fails to lock into
position properly, the function of
some controls may be impaired,
and some segments of the display
may not become illuminated. If this
occurs, press RELEASE and reinstall
the front panel.
