WARNING!!
WHEN  SERVICING,  DO  NOT  APPROACH  THE  LASER
EXIT  WITH  THE  EYE  TOO  CLOSELY.  IN  CASE  IT  IS
NECESSARY  TO  CONFIRM  LASER  BEAM  EMISSION,
BE  SURE  TO  OBSERVE  FROM  A  DISTANCE  OF
MORE   THAN   25  cm  FROM  THE  SURFACE  OF  THE
OBJECTIVE  LENS  ON  THE  OPTICAL  PICK-UP  BLOCK.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.

LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part having
a return to chassis, must not exceed 0.5 mA (500 microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A.  Follow the manufacturers' instructions to use these
instruments.
2. A battery-operated AC milliammeter.  The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter.  The “limit” indica-
tion is 0.75V, so analog meters must have an accurate low-
voltage scale.  The Simpson 250 and Sanwa SH-63Trd are ex-
amples of a passive VOM that is suitable.  Nearly all battery
operated digital multimeters that have a 2V AC range are suit-
able.  (See Fig. A)
1. Check the area of your repair for unsoldered or poorly-sol-
dered connections.  Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly transis-
tors, that were installed during a previous repair.  Point them
out to the customer and recommend their replacement.
4. Look for parts which, though functioning, show obvious signs
of deterioration.  Point them out to the customer and recom-
mend their replacement.
5. Check the line cord for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.
6. Check the B+ voltage to see it is at the values specified.
7. Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
CAUTION:
The use of optical instrument with this product will increase eye
hazard.
This CD/DVD player is CLASS 1 LASER PRODUCT.
Unleaded solder
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)
 : LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40
°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350
°C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow) than
ordinary solder so use caution not to let solder bridges occur
such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

Precautions
Caution-The  use  of  optical  instruments  with  this  product 
will  increase  eye  hazard.
To  prevent  fire  or  shock  hazard,  the  apparatus  shall  not  be 
exposed  to  dripping  or  splashing  and  do  not  place  objects 
filled  with  liquids,  such  as  vases,  on  the  apparatus.
Should  any  solid  object  or  liquid  fall  into  the  cabinet, 
unplug  the  player  and  have  it  checked  by  qualified 
personnel  before  operating  it  any  further.
Do  not  put  any  foreign  objects  in  the  DC  IN  9.5V  (external 
power  input)  jack.
This  car  adaptor  is  not  intended  to  be  serviced.Should  the 
product  cease  to  function  in  its  intended  manner,  it  should 
be  returned  to  the  manufacturer  or  to  be  discarded.
On  safety
On  temperature  increases
The  power  requirements  and  power  consumption  of  this 
unit  are  indicated  on  the  AC  adaptor.  Check  that  the  unit's 
operating  voltage  is  identical  with  your  local  power  supply.
Heat  may  build  up  while  charging  or  during  extended  use. 
This  is  not  a  malfunction.
If  the  surrounding  temperature  is  very  high,  the  protective 
function  will  turn  off  the  player  automatically.  Leave  the 
player  in  a  cool  location  for  about  30  minutes  before  using 
it  again.
On  power  sources
Use  only  the  supplied  AC  adaptor.  Do  not  use  any  other 
AC  adaptor.  It  may  cause  a  malfunction.
Polarity  of  the  plug
If  the  AC  adaptor  causes  interference  to  radio 
reception,  move  it  away  from  the  radio.
Do  not  touch  the  AC  adaptor  with  wet  hands.
Even  when  the  player  is  turned  off,  it  is  still  connected 
to  the  AC  power  source  (mains)  as  long  as  it  remains 
connected  to  wall  outlet.
If  you  are  not  going  to  use  the  player  for  a  long  time,  be 
sure  to  disconnect  the  player  from  the  wall  outlet.  To 
disconnect  the  AC  power  cord  (mains  lead),  grasp  the 
plug  itself;  never  pull  the  cord.     
Should  the  AC  power  cord  need  to  be  changed,  have  it 
done  at  a  qualified  service  shop  only.
Use  a  commercially  available  AC  plug  adaptor,  if 
necessary,  depending  on  the  design  of  the  wall  outlet.

CAUTION
Never  expose  the  battery  pack  to  temperatures  above 
140  °F  (60  °C)  such  as  in  a  car  parked  in  the  sun  or  under 
direct  sunlight.
On  the  rechargeable  battery 
Charge  the  battery  before  you  start  using  it.
Do  not  allow  dust  to  come  into  contact  with  the  battery 
terminals  of  the  player  and  battery.
Do  not  short  the  terminals.
Do  not  open  the  terminal  covers  of  the  player.
Do  not  leave  the  battery  in  a  place  subject  to  direct 
sunlight,  or  in  a  car  with  its  windows  closed.
Keep  the  battery  dry.
Use  only  the  battery(NP-FX110)  supplied  with  this 
player(DVP-FX815).  Other  rechargeable  batteries 
supplied  with  other  models  cannot  be  used  with  this 
player.  Note  that  is  a  danger  of  explosion  if  battery  is 
incorrectly  replaced.
Do  not  disassemble.
Do  not  incinerate.
Dispose  of  used  batteries  promptly.
Certain  countries  may  regulate  disposal  of  the 
battery  used  to  power  this  product.  Please  consult 
with  your  local  authority. 
To  dispose  of  the  rechargeable  battery
To  store  the  rechargeable  battery
On  charging  the  rechargeable  battery
The  battery  is  consumed  gradually  as  time  elapses 
even  if  is  not  used,  In  order  to  prevent  the  battery  from 
deteriorating,  store  it  as  follows:
Remove  the  battery  from  the  player  after  use.  (Even  if 
the  player  is  off,  it  still  uses  some  power.)
Use  up  the  battery  completely  on  the  player  before 
storing  it.
Keep  the  battery  in  a  cool  location  to  prevent  it  from 
deteriorating.
Charge  and  use  the  battery  at  least  once  every  6 
months.
Heat  may  build  up  in  the  battery  while  charging.  This  is 
not  a  malfunction.
When  the  battery  life  of  a  fully  charged  battery  becomes 
about  half  the  normal  life,  you  may  need  to  replace  the 
battery  with  a  new  one.
Disconnect  the  battery  from  the  player  as  soon  as  it  has 
been  charged.  Leaving  it  connected  may  result  in 
reduced  battery  performance.
