Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
Dispose of used batteries according to the instructions.

This unit uses 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.)

Be careful to the following points to solder or unsolder.

•   Set the soldering iron tip temperature to 350 °C approximately. 

If cannot control temperature, solder/unsolder at high temperature 
for a short time.
Caution:  The printed pattern (copper foil) may peel away if the 

heated tip is applied for too long, so be careful!  

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.

•   Be sure to control soldering iron tips used for unleaded solder and 

those for leaded solder so they are managed separately. Mixing un-
leaded solder and leaded solder will cause detachment phenomenon.

After correcting the original service problem, perform the following 

safety checks before releasing the set to the customer.

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
 

•   Set the soldering iron tip temperature to 350 °C approximately.

 

•   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.

When you replace to the repairing board, the written destination data of repairing board also might be changed to original setting.
Start the Adjust Manual in the Adjust Station and execute the “DESTINATION DATA WRITE”.

When you replace to the repairing board, get the data from the former one.
Start the Adjust Manual in the Adjust Station and perform “RESTORE DATA” to get the data. 
The data getting for this model is as follows.

• USB SERIAL No.
• Angular Velocity Sensor Sensitivity adjustment
• AWB standard data input & check, Color reproduction check

Note: When you cannot read data from the former replace the same time SY-282 board and lens.

PMB Portable has been written in internal memory.
SY-282 board for service is supplied with written the PMB Portable.

The set is shipped with a unique ID (USB Serial No.) written in it.
This ID has not been written in a new board for service, and therefore it must be entered after the board replacement.
Start the Adjust Manual in the Adjust Station and execute the “USB SERIAL No. INPUT”.

When you replace to the reparing board, write down the sensitivity displayed on the angular velocity sensor (SE401).
Start the Adjust Manual in the Adjust Station and execute the “Angular velocity sensor sensitivity adj”.

Note: The sensor sensitivity of SE401 of SY-282 board is written only repair parts.

The data can be copied/erased by the operations on the HOME screen. (When erasing the data, execute formatting the internal memory.)

Note 1:When replacing the SY-282 board, erase the data in internal memory of the board before replacement.
Note 2:When replacing the SY-282 board, execute formatting and initialize the internal memory after replacement.

Copies all images in the internal memory to a memory card.

1.  Insert a memory card with sufficient free capacity into the camera.

2.  MENU 

 (Settings) 

 (Memory Card Tool) 

 [Copy] 

 [OK] 

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.
Images cannot be copied individually.
The original images in the internal memory are retained even after copying. To delete the
contents of the internal memory, remove the memory card after copying, then format the
internal memory ([Format] in [Internal Memory Tool]).
A new folder is created on the memory card and all the data will be copied to it. You cannot
choose a specific folder and copy images to it.

Formats the memory card or the internal memory. When you use a memory card with this
camera for the first time, it is recommended to format the card using the camera for stable
performance of the memory card before shooting. Note that formatting permanently erases all
data on the memory card, and is unrecoverable. Save precious data on a computer, etc.

1.  MENU 

 (Settings) 

 (Memory Card Tool) or

 [OK] 

Note that formatting permanently erases all data including even protected images.

Usually, the camera has been set so as to disable the data writing from the PC to the internal memory of the camera.
This setting must be changed temporarily when the data is to be written to the internal memory such as a case after the board replacement.
To change settings is enabled with using the writing enabler tool (Write Enable Tool) on the Adjust Manual is activating from the Adjust Station.

1)  Start the Adjust Manual from the Adjust Station.

2) Click 

 (Write Enable Tool) button.

3)  Click “Activate Write Enable Mode” button.

4)  Upon completion of the setting change, the following message will be displayed.

5)  Return the driver to the original one, and connect the PC to the camera (USB mode: Mass Storage).
6)  Write the data read out into the PC to the internal memory of the camera.
7)  Disconnect the PC from the camera, and turn off the camera.

Note: By turning off the camera, the write enable setting is reset.

When problems occur while the unit is operating, the self-diagnosis func-
tion starts working, and displays on the LCD screen what to do.
Details of the self-diagnosis functions are provided in the Instruction 
manual.

When problems occur while the unit is operating, the LCD screen shows 
a 4-digit display consisting of an alphabet and numbers, which blinks at 
3.2 Hz. This 5-character display indicates the “repaired by:”, “block” in 
which the problem occurred, and “detailed code” of the problem.
