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.
Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be
damaged by heat.
✩Replacement of IC1001 used in this set requires a special tool.
•The voltage and waveform of CSP (chip size package) cannot
be measured, because its lead layout is different from that of
conventional IC.
•Lead layouts surface
Lead layout of
conventional IC CSP (chip size package)
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 viscou-s (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. Operating instructiondd

Index to Parts and Controls
Identifying the front and rear panels of the unit
1Lens mount (HOLD on/off, Camera on/off,
camera self mode)
You can set the unit to the following modes as you
rotate the lens mount to the following position:
HOLD on: When you rotate the lens mount to
“HOLD”, “HOLD”will appear for 3 seconds and
then the display will be turned off.
• During recording and playback: recording or
playback continues but the functions of the
buttons are locked.The live view mode, if
activated, will be turned off.
• During stop: The unit enters into the standby
mode.
To cancel the HOLD function
Rotate the lens mount to select other position.
zHOLD off/Camera off: When you rotate the lens
mount to the “z” position, you can record a
message but cannot shoot an image.If the lens
mount is turned from the HOLD position, HOLD
will be canceled.
Camera on (Open): Rotate the lens mount further
than “zHOLD off/Camera off” position and to
the next position it clicks into place.This position
is called “Camera on (Open)”position in this
manual where the camera is activated.You can
turn on the live view mode.
Camera on (Self): Rotate the lens mount further
than “Camera on (Open)”position until it clicks
into place.The lens faces towards you.This
position is called “Camera on (Self)”positionYou
can turn on the live view and can shoot your self
view.
2Macro switch (off/ on)
You can turn on or off the macro feature when you
shoot an image in the live-view mode.
on:Turns on the macro feature for shooting close-
ups.
off:Turns off the macro feature.

16-1. F/W Upgrade method
Ifthe firmwareisrequired to beupdatedfor correction ofbugsfound
after mass production, the F/W should be upgraded according to
the following procedure:
(1) Connect the AC adapter and supply power from anAC outlet.
(2) Connect the set with a PC via USB and copy the following
file to the root directory in the Nancy drive. (This file is
distributed for correction of bugs found.)
* MSFWUPGR.UPG (file for upgrade)
(3) Ensure the copy is complete and disconnect USB connection.
(4) Set TEST MODE and select “F/W Update”.
(5) Press ukey to start the F/W Update.
(6) The OPE-LED is lit red to green to orange and then lit out.
Now the update is complete.
(7) Select “Version” in TEST MODE and check the version.
NOTE: The upgrade will fail if the power is off or RESET is pressed during
upgrade.
(This will result in malfunctions such as power not turned on and
incorrect operation during operation of the set.)
If this problem occurs, the set need be disassembled for upgrade.
Contact the Design Department.
17. Lcd Contrast
Adjust the LCD contrast.
Adjustment method:
Check the color bars on the upper half of the screen and make sure
that the colors are correct.
Use >key to make the contrast stronger. Use .key to
make the contrast weaker.
By adjusting the contrast, adjust so that there are no black and white
crushes on the boundaries between 3 lines on each of the left and
right sides and that the color bars can be recognized symmetrically.
18. MicSens
Correct the sensitivity balance of the left and right built-in
microphones due to variations in sensitivity dependent on the single
microphone.
*Provide an anechoic box.
*Install a speaker and a set stand in the box.
*Fix the set on the stand. (The set should face the speaker
straight.)
*Close the lid on the box.
*Produce a 1kHz sinusoidal wave through the speaker. (Sound
level: 80 dBSPL or so)
*Start adjustment using ukey
*Wait for 30 seconds. The adjustment is OK if OK is displayed.
NG or TIMEOUT is displayed if the adjustment fails.
*In terms of audibility, ensure there is no difference in level
between the left and right built-in microphones.
Set the adjustment mode and place the set on the stand in the
box.
19. Camera Init
Write the initial settings to the camera module itself.
20. Camera Adjust
