Safety Information
(continued)
Observe the following cautions when installing.
Refer wiring and installation to qualifi ed service
personnel.
Installation of this unit requires special skills and
experience. For maximum safety, have it installed by
your dealer. Panasonic is not liable for any problems
resulting from your own installation of the unit.
Follow the instructions to install and wire the product.
Not following the instructions to properly install and
wire the product could cause an accident or fi re.
Take care not to damage the leads.
Prevent them from getting caught in the vehicle
chassis, screws, and moving parts such as seat rails.
Do not scratch, pull, bend or twist the leads. Do not run
them near heat sources or place heavy objects on them.
If leads must be run over sharp metal edges, protect
the leads by winding them with vinyl tape or similar
protection.
Use the designated parts and tools for installation.
Use the supplied or designated parts and appropriate
tools to install the product. The use of parts other than
those supplied or designated may result in internal
damage to the unit. Faulty installation may lead to an
accident, a malfunction or fi re.
Do not install the product where it is exposed to
strong vibrations or is unstable.
Avoid slanted or strongly curved surfaces for
installation. If the installation is not stable, the unit may
fall down while driving and this can lead to an accident
or injury.
We strongly recommended you to wear gloves for
installation work to protect yourself from injuries.
Failure to heed this caution may result in an accident
and/or injury.
Be sure to grip both sides of this unit securely before
attempting to move it.
Since this unit is quite heavy, the unit may fall down
and this can lead to an accident or injury.
Cover the unused terminals with insulating tape to
prevent them from short circuiting.
When an extension lead is used, it should be as
thick and short as possible; connect it fi rmly with
insulating tape.
Wire breaks and short circuits can cause electrical
shock or fi re.
Caution
Use the spacer included when installing the unit so
that the fan and air hole on the base side of the unit
are not covered. <CY-PAD1003W>
If the fan and air hole on the base side of the unit are
covered, the unit will become extremely hot and may
fail.
Caution for mounting the unit:
Never mount the unit in any of the following locations
to avoid damage due to overheating;
• Near the heater port.
• Places like the dashboard or rear deck, where it may
be exposed to direct sunlight.
Do not mount the unit near the door, where it could be
exposed to rain.
Keep a safe distance between the unit and other
electronic equipment.
When a short circuit occurs, such as in the speaker
output terminal, etc. the overload protection circuit will
operate. This circuit protects the power amplifi er from
further damage when a short circuit occurs. Operation
will temporarily stop. In this case, check the cause of
the short-circuit and if the problem is fi xed, normal
operation will resume.
Since the power amplifi er has a very large output, the
unit should be installed in the trunk of your car.
Do not install this unit under a carpet, otherwise the
unit may fail because of immature heat dissipation.
In case more than one power amplifi er is used, make
sure to employ the power cord and the fuse having
the current capacity larger than the total current
corresponding to the maximum consumption powers
of all the amplifi ers.
Caution for the power cord (option):
Follow an expert’s instruction for the use of the cord
separately sold.
For the power, make sure to use the battery lead (yellow)
separately sold and specially designed for Panasonic
car-audio/AV system, and to connect directly to the car
battery. Use the cord having the fuse capacity larger
than that of this unit. Connect the power cord and other
cords corresponding to the power supply after all the
connections to the speaker are completed.
Keep the battery lead (yellow) away from the speaker
cord.
Make sure to use the ground lead (black) separately
sold and specially designed for car audio system, and
to connect it to the metal portion of the car chassis.
Wire the battery lead (yellow), the ground lead (black),
the speaker cords, and this unit with as much distance
as possible from the antenna, the antenna cords and
the car stereo (car radio).
If the ground wire is common to both left/right and
front/rear speaker wirings, this unit cannot be used.
Always use the independent lead wire for the speakers
to be used. In this case, redo the wiring.
Caution for the speaker cord (option):
The speaker cords and the power amplifi er unit should
be kept away from the antenna and antenna extension
cord.
Do not directly ground the speaker cords; do not share
the negative leads of multiple speakers.
When using the RCA cords, keep away from the
speaker cords.
Caution for the speaker (option):
Use speakers with a suitable maximum input.
In case of 4-channel/3-channel connection
<CY-PA4003W>:
Use speakers with the impedance of 28 .
In case of 2-channel/stereo connection:
Use speakers with the impedance of 48 .
