Clarion DRX9375R User Manual

_ To engineers in charge of repair
or inspection of our products.
Before repair or inspection,make sure to fol-
_low the instructions so that customers and
"Engineers in charge of repair or inspection can
“avoid suffering any risk or injury.
1.
Use specified parts.
The system uses parts with special safety features
against fire and voltage.Use only parts with equiva-
lent characteristics when replacing them.
The use of unspecified parts shall be regarded as re-
modeling for which we shall not be liable. The onus of
product liability (PL) shall not be our responsibility in
cases where an accident or failure is as a result of
unspecified parts being used.
2. Place the parts ard wiring back in their original posi-
tions after replacement or re-wiring.
For proper circuit construction,use of insulation
tubes,bonding,gaps to PWB,etc,is involved. The wir-
ing connection and routing to the PWB are specially
planned using clamps to keep away from heated and
high voltage parts.Ensure that they are placed back
in their original positions after repair or inspection.
If extended damage is caused due to negligence dur-
ing repair,the legal responsibility shall be with the re-
pairing company. .
3. Check for safety after repair.
Check that the screws,parts and wires are put back
securely in their original position after repair.Ensure
for safety reasons there is no possibility of secondary
ploblems around the repaired spots.
If extended damage is caused due to negligence of
repair,the legal responsibility shall be with the repair-
ing company.
4. Caution in removal and making wiring connection to
the parts for the automobile.
Disconnect the battery terminal after turning the igni-
tion key off.If wrong wiring connections are made with
the battery connected, a short circuit and/or fire may
occur.If extensive damage is caused due to negligence
of repair,the legal responsibility shall be with the re-
pairing company.
5. Cautions regarding chips.
Do not reuse removed chips even when no abnormal-
ity is observed in their appearance.Always replace
them with new ones.(The chip parts include
resistors,capacitors, diodes, transistors,etc). The nega-
tive pole of tantalum capacitors is highly susceptible
to heat,so use special care when replacing them and
check the operation afterwards.
6. Cautions in handling flexible PWB
Before working with a soldering iron,make sure that
the iron tip temperature is around 270°C. Take care
not to apply the iron tip repeatediy(more than three
times)to the same patterns.Also take care not to ap-
ply the tip with force.
7. Turn the unit OFF during disassembly and parts

replacement.Recheck ail work before you apply power
to the unit.
Cautions in checking that the optical pickup lights up.
9-2.
9-3.
The laser is focused on the disc reflection surface
through the lens of the optical pickup. When checking
that the laser optical diode lights up,keep your eyes
more than 30cms away from the lens.Prolonged view-
ing of the laser within 30cms may damage your eye-
sight.
9. Cautions in handling the optical pickup
The laser diode of the optical pickup can be damaged
by electrostatic charge caused by your clothes and
body.Make sure to avoid electrostatic charges on your
clothes or body,or discharge static electricity before
handling the optical pickup.
9-1. Laser diode
The laser diode terminals are shorted for trans-
portation in order to prevent electrostatic
damage.After replacement,open the shorted
circuit.When removing the pickup from the
mechanism,short the terminals by soldering them
to prevent this damage.
Actuator
The actuator has a powerful magnetic circuit. If
a magnetic material is put close to it.its charac-
teristics will change.Ensure that no foreign sub-
stances enter through the ventilation slots in the
cover.
Cleaning the lens
Dust on the optical lens affects performance.To
clean the lens,apply a small amount of
isopropylalcohol to lens paper and wipe the
lens gently.
MNOTES
1. The DCP can easily be damaged by shocks. After
removing it,be careful not to drop it or subject it to
strong shocks.
2. The connector connecting the main unit and the DCP
is an extremely important part.Be careful not to dam-
age it by pressing on it withfingernails,screwdriver,etc.
3. CD-ROMs cannot be played with CD changer.
MCAUTIONS
This appliance contains a laser system and is classified
as a "CLASS 1 LASER PRODUCT".To use this model
properly,read this Owner's Manual carefully and keep
this manual for your future reference.In case of any
trouble with this. player,please contact your nearest
"AUTHRIZED service station".To prevent direct expo-
