1.
Check the area of your repair for unsoldered or poorly-soldered
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
transistors, that were installed during a previous repair.  Point
them out to the customer and recommend their replacement.
4.
Look for parts which, through functioning, show obvious signs
of deterioration.  Point them out to the customer and
recommend their replacement.
5.
Check the B+ voltage to see it is at the values specified.
6.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270°C
during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.

Method for Copying the Data in Internal Memory
The data can be copied by the operations on the Setup screen.
Copies all images in the internal memory to a “Memory Stick Duo”.
1 Insert a “Memory Stick Duo” having 32 MB or larger capacity.
2 Select [Copy] with v/V/b/B on the control button, then press z.
The message “All data in internal memory will be copied” appears.
3 Select [OK] with v, then press z.
Copying starts. 
To cancel the copying
Select [Cancel] in step 
3, then press z.
• Use a fully charged battery pack. If you attempt to copy image files using a battery pack with little 
remaining charge, the battery pack may run out, causing copying to fail or possibly corrupting the data.
• You cannot copy individual images.
• The original images in the internal memory are retained even after copying. To delete the contents of the 
internal memory, remove the “Memory Stick Duo” after copying, then execute the [Format] command in 
[
 Internal Memory Tool] .
• When you copy the data in the internal memory to the “Memory Stick Duo”, all the data will be copied. 
You cannot choose a specific folder on the “Memory Stick Duo” as the destination for the data to be 
copied.
• Even if you copy data, a DPOF (Print order) mark is not copied.

IMPORTANT 
SAFEGUARDS
For your protection, please read these safety 
instructions completely before operating 
the appliance, and keep this manual for 
future reference.
Carefully observe all warnings, precautions 
and instructions on the appliance, or the one 
described in the operating instructions and 
adhere to them.
[
Power Sources
This set should be operated only from the type of 
power source indicated on the marking label. If 
you are not sure of the type of electrical power 
supplied to your home, consult your dealer or 
local power company. For those sets designed to 
operate from battery power, or other sources, refer 
to the operating instructions.
[
Polarization
This set may be equipped with a polarized ac 
power cord plug (a plug having one blade wider 
than the other).
This plug will fit into the power outlet only one 
way. This is a safety feature. If you are unable to 
insert the plug fully into the outlet, try reversing 
the plug. If the plug should still fail to fit, contact 
your electrician to have a suitable outlet installed. 
Do not defeat the safety purpose of the polarized 
plug by forcing it in.
[
Overloading
Do not overload wall outlets, extension cords or 
convenience receptacles beyond their capacity, 
since this can result in fire or electric shock.
[
Object and Liquid Entry
Never push objects of any kind into the set 
through openings as they may touch dangerous 
voltage points or short out parts that could result 
in a fire or electric shock. Never spill liquid of any 
kind on the set.
[
Attachments
Do not use attachments not recommended by the 
manufacturer, as they may cause hazards.
English
WARNING
For Customers in the U.S.A.
This symbol is intended to 
alert the user to the presence 
of uninsulated “dangerous 
voltage” within the 
product's enclosure that may 
be of sufficient magnitude 
to constitute a risk of 
electric shock to persons.
This symbol is intended to 
alert the user to the presence 
of important operating and 
maintenance (servicing) 
instructions in the literature 
accompanying the 
appliance.
Use
3
[
Cleaning
Unplug the set from the wall outlet before 
cleaning or polishing it. Do not use liquid cleaners 
or aerosol cleaners. Use a cloth lightly dampened 
with water for cleaning the exterior of the set.
[
Water and Moisture
Do not use power-line operated sets near water – 
for example, near a bathtub, washbowl, kitchen 
sink, or laundry tub, in a wet basement, or near a 
swimming pool, etc.
[
Power-Cord Protection
Route the power cord so that it is not likely to be 
walked on or pinched by items placed upon or 
against them, paying particular attention to the 
plugs, receptacles, and the point where the cord 
exits from the appliance.
[
Accessories
Do not place the set on an unstable cart, stand, 
tripod, bracket, or table. The set may fall, causing 
serious injury to a child or an adult, and serious 
damage to the set. Use only a cart, stand, tripod, 
bracket, or table recommended by the 
manufacturer.
[
Ventilation
The slots and openings in the cabinet are provided 
for necessary ventilation. To ensure reliable 
operation of the set, and to protect it from 
overheating, these slots and openings must never 
be blocked or covered.
– Never cover the slots and openings with a cloth 
or other materials.
– Never block the slots and openings by placing 
the set on a bed, sofa, rug, or other similar 
surface.
– Never place the set in a confined space, such as a 
bookcase, or built-in cabinet, unless proper 
ventilation is provided.
– Do not place the set near or over a radiator or 
heat register, or where it is exposed to direct 
sunlight.
[
Lightning
For added protection for this set during a lightning 
storm, or when it is left unattended and unused for 
long periods of time, unplug it from the wall 
outlet and disconnect the antenna or cable system. 
This will prevent damage to the set due to 
lightning and power-line surges.
[
Damage Requiring Service
Unplug the set from the wall outlet and refer 
servicing to qualified service personnel under the 
following conditions:
– When the power cord or plug is damaged or 
frayed.
– If liquid has been spilled or objects have fallen 
into the set.
– If the set has been exposed to rain or water.
– If the set has been subject to excessive shock by 
being dropped, or the cabinet has been damaged.
– If the set does not operate normally when 
following the operating instructions. Adjust only 
those controls that are specified in the operating 
instructions. Improper adjustment of other 
controls may result in damage and will often 
require extensive work by a qualified technician 
to restore the set to normal operation.
– When the set exhibits a distinct change in 
performance – this indicates a need for service.
[
Servicing
Do not attempt to service the set yourself as 
opening or removing covers may expose you to 
dangerous voltage or other hazards.
Refer all servicing to qualified service personnel.
[
Replacement parts
When replacement parts are required, be sure the 
service technician has used replacement parts 
specified by the manufacturer that have the same 
characteristics as the original parts.
Unauthorized substitutions may result in fire, 
electric shock, or other hazards.
[
Safety Check
Upon completion of any service or repairs to the 
set, ask the service technician to perform routine 
safety checks (as specified by the manufacturer) 
to determine that the set is in safe operating 
condition.
