Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

Unleaded solder
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.

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

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.

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.

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-191 board, erase the data in internal memory of the board before replacement.
Note 2:
When replacing the SY-191 board, execute formatting and initializing the internal memory after replacement.

1-5. HOW TO WRITE DATA TO INTERNAL MEMORY
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 the setting, use the write enable tool “WriteEnableTool.exe”.
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 the setting, use the write enable tool “WriteEnableTool.exe”.
Data writing method

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.
