Installation
Caution
When you install this unit in your car, do not remove the
detachable front panel.
If the detachable front panel is removed during installation, you
might press too hard and warp the metal plate that holds it in
place.
The main unit must be mounted within 35 degrees of the
horizontal plane, back to front.
1
Remove the mounting sleeve from the main unit (refer to
“Removal” on page 48).
* If the installed mounting sleeve is loose in the dashboard, the
pressure plates may be bent slightly to remedy the problem.
2
Reinforce the head unit with a metal mounting strap (not
supplied). Secure the ground lead of the unit to a clean
metal spot using a screw (
*1
) already attached to the
vehicle’s chassis.
Connect each input lead coming from an amplifier to the
corresponding output lead coming from the left rear of the
CDE-HD138BT/CDE-HD137BT. Connect all other leads of the
CDE-HD138BT/CDE-HD137BT according to details described in
the CONNECTIONS section.
Note
• For the screw marked “
*2
”, use an appropriate screw for the chosen
mounting location.
3
Slide the CDE-HD138BT/CDE-HD137BT into the dashboard
until it clicks. This ensures that the unit is properly locked
and will not accidentally come out from the dashboard.
Install the detachable front panel.
1
Remove the detachable front panel.
2
Insert the bracket keys into the unit, along the guides on
either side. The unit can now be removed from the
mounting sleeve.
Caution
Do not block the unit’s fan or heat sink, thus preventing air
circulation. If blocked, heat will accumulate inside the unit and may
cause a fire.
