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.
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.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.

Format
If you cannot play back a Music file for the Slide Show, the Music file might be corrupted. If 
this happens, perform [Format Music].
When [Format Music] is performed, all the Music files are erased. Use the supplied software 
“Music Transfer” to activate [Download Music].

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.
