In addition, be sure that there are no pinched wires, etc.
7 Make sure screws and soldering scraps do not remain inside the product.
Please check that neither solder debris nor screws remain inside the product.
8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.
9 There should be no spark traces or similar marks on the power plug.
D
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the power cord if necessary.
0 Safe environment should be secured during servicing.
When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
Please pay attention to your surroundings and repair safely.

To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.
3. Lubricants, Glues, and Replacement parts
E
Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.
4. Cleaning
For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
cleaning should be performed to restore their performances.
5. Shipping mode and Shipping screws
To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be
installed before shipment. Please be sure to follow this method especially if it is specified in this manual.

A
Removing the Case (Fig. 1)
Case
1 Remove two black screws (M3 x 10).
2 Remove six white screws (M3 x 6).
3 Remove four black screws (M3 x 5).
Caution)
When you disassemble/re-assemble the Product
with it placed upside down, take care not to
damage the top surface.
The Product uses several different types of
screws. Take care not to confuse them during
re-assembly.

Caution)
The Amp Unit is adhered on the Heat Sink with
silicon grease. This means forcibly removing the
Amp Unit from the Heat Sink may break the
PCB.

3 remove the two black screws (M3 x 5).
Tighten screws whose length is M3 x 8 or
more into the two screw holes so as to
raise the Amp Unit above the Heat Sink.
Then, remove the Amp Unit.
(Since screw threads differ, 1 and 2 screws cannot be used.)

Caution when re-assembling the Amp Unit and the Heat Sink
Be aware that the RCA Terminal may break
unless the Amp Unit and the Heat Sink are
assem-bled following the correct procedures
given below.

(CN111)
Amp Unit
1) Secure the RCA-side Panel on the Heat Sink
with screws. (Fig. 2)
2) Place the Amp Unit on the Heat Sink aligning
with two studs. (Fig. 4)
3) Move the Amp Unit until the RCA Holder on
the Amp Unit comes in contact with the inside
of the Panel. (Fig. 4)
E
Move the Amp Unit
Caution in steps 2) and 3)
When you place the Amp Unit on the Heat Sink,
you will find no positioning marks to determine
the direction of two panels. To position them
correctly, the Amp Unit needs to be moved to
the place where it comes in contact with the
RCA-side panel.
If you do not position them, an excessive force
can be applied to the RCA Terminal. This may
result in breakage.

4) Secure the RCA-side Panel and the RCA
Holder with screws. (Fig. 2)

• When using with an RCA equipped car stereo (standard output of 500 mV), set to the
NORMAL position. When using with an RCA equipped Pioneer car stereo with max.
output of 4 V or more, adjust level to match the car stereo output level.
• If you hear too much noise when using the speaker input terminals, turn the gain control
counter-clockwise.
If the sound level is too low, even when the volume of the car stereo used along
with this power amplifier is turned up, turn gain control on the front of the
power amplifier clockwise. If the sound distorts when the volume is turned up,
turn the gain control counter-clockwise.
