SAFETY PRECAUTIONS The following check
should be performed for the continued
protection of the customer and service
technician. LEAKAGE CURRENT CHECK
Measure leakage current to a known earth
ground (water pipe, conduit, etc.) by
connecting a leakage current tester such as
Simpson Model 229-2 or equivalent between
the earth ground and all exposed metal parts
of the appliance (input/output terminals,
screwheads, metal overlays, control shaft,
etc.). Plug the AC line cord of the
appliance directly into a 120V AC 60 Hz
outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL
SHOCK HAZARD AND MUST BE CORRECTED BEFORE
RETURNING THE APPLIANCE TO THE CUSTOMER. 2.
PRODUCT SAFETY NOTICE Many electrical
and mechanical parts in the appliance have
special safety related characteristics.
These are often not evident from visual
inspection nor the protection afforded by
them necessarily can be obtained by using
replacement components rated for voltage,
wattage, etc. Replacement parts which have
these special safety characteristics are
identified in this Service Manual.
Electrical components having such features
are identified by marking with a > on the
schematics and on the parts list in this
Service Manual. The use of a substitute
replacement component which does not have
the same safety characteristics as the
PIONEER recommended replacement one, shown
in the parts list in this Service Manual,
may create shock, fire, or other hazards.
Product Safety is continuously under review
and new instructions are issued from time to
time. For the latest information, always
consult the current PIONEER Service Manual.
A subscription to, or additional copies of,
PIONEER Service Manual may be obtained at a
nominal charge from PIONEER. Leakage current
tester Reading should not be above Device
0.5 mA under test Test all exposed metal
surfaces Also test with plug reversed (Using
AC adapter plug as required) Earth ground AC
Leakage Test (FOR USA MODEL ONLY) WARNING
This product contains lead in solder and
certain electrical parts contain chemicals
which are known to the state of California
to cause cancer, birth defects or other
reproductive harm. Health & Safety Code
Section 25249.6 - Proposition 65 NOTICE
(FOR CANADIAN MODEL ONLY) Fuse symbols (fast
operating fuse) and/or (slow operating fuse)
on PCB indicate that replacement parts must
be of identical designation. REMARQUE (POUR
MODÈLE CANADIEN SEULEMENT) Les symboles de
fusible (fusible de type rapide) et/ou
(fusible de type lent) sur CCI indiquent que
les pièces de remplacement doivent avoir la
même désignation. This service manual is
intended for qualified service technicians ;
it is not meant for the casual do-ityourselfer.
Qualified technicians have the necessary
test equipment and tools, and have been
trained to properly and safely repair
complex products such as those covered by
this manual. Improperly performed repairs
can adversely affect the safety and
reliability of the product and may void the
warranty. If you are not qualified to
perform the repair of this product properly
and safely, you should not risk trying to do
so and refer the repair to a qualified
service technician. DJM-400 3 5 6 7 8 5
6 7 8 C D F A B E [Important Check Points
for Good Servicing] In this manual,
procedures that must be performed during
repairs are marked with the below symbol.
Please be sure to confirm and follow these
procedures. 1. Product safety Please conform
to product regulations (such as safety and
radiation regulations), and maintain a safe
servicing environment by following the
safety instructions described in this
manual. 1 Use specified parts for repair.
Use genuine parts. Be sure to use important
parts for safety. 2 Do not perform
modifications without proper instructions.
Please follow the specified safety methods
when modification(addition/change of parts)
is required due to interferences such as
radio/TV interference and foreign noise. 3
Make sure the soldering of repaired
locations is properly performed. When you
solder while repairing, please be sure that
there are no cold solder and other debris.
Soldering should be finished with the proper
quantity. (Refer to the example) 4 Make sure
the screws are tightly fastened. Please be
sure that all screws are fastened, and that
there are no loose screws. 5 Make sure each
connectors are correctly inserted. Please be
sure that all connectors are inserted, and
that there are no imperfect insertion. 6
Make sure the wiring cables are set to their
original state. Please replace the wiring
and cables to the original state after
repairs. 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. 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. 2.
Adjustments 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. 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. 3.
Lubricants, Glues, and Replacement parts Use
grease and adhesives that are equal to the
specified substance. Make sure the proper
amount is applied. 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. 4 DJM-400 1 2 3 4 1 2 3 4 C D F A B

CONTRAST OF PCB ASSEMBLIES DWX2524,
DWX2525 and DWX2516 are constructed the same
except for the following : DWX2519 and
DWX2526 are constructed the same except for
the following : Parts marked by "NSP" are
generally unavailable because they are not
in our Master Spare Parts List. The mark
found on some component parts indicates the
importance of the safety factor of the part.
Therefore, when replacing, be sure to use
parts of identical designation. When
ordering resistors, first convert resistance
values into code form as shown in the
following examples. Ex.1 When there are 2
effective digits (any digit apart from 0),
such as 560 ohm and 47k ohm (tolerance is
shown by J=5%, and K=10%). Ex.2 When there
are 3 effective digits (such as in high
precision metal film resistors). 5 6 1 4 7 3

checking the level-meter LED (METERTEST)
This is a mode in which the channel level
indicators are lit one by one. On the BPM
display, "-8-" is displayed. Each time a
HEADPHONES cue button (CH-1/CH-2/MASTER) is
pressed, the level indicator LEDs
corresponding to that channel are lit one by
one, from the bottom. At first, all the LEDs
are unlit. When a HEADPHONES cue button is
pressed 7 times, the uppermost LED will be
lit. Then when the same HEADPHONES cue
button is pressed again, all the LEDs go
dark. Thus, this process can be repeated
from the beginning. 72 DJM-400 1 2 3 4 1 2 3
