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.

Click the [INTERNAL MEMORY (Write Enable) ] button on the Main Menu screen, and the follwing “INTERNAL MEMORY (Write
Enable)” screen will appear.

[Preparations]
•

Insert the battery pack.

•

Remove the Memory Stick.

1) Click the [Activate Write Enable] button.
2) Upon completion of the setting change, the following message will be displayed.

3) Disconnect the lead wire from the GND of the modified multioutput stand.
4) Disconnect the USB cable and reconnect the USB cable to activate the MassStorage mode for the USB connection.
5) Write the data read out into the PC to the internal memory of the camera.
6) Exit the adjustment program, and turn off the power of the camera, and the write enable setting will be cancelled.

When “FLASH error” (Self-diagnosis Code E : 91 : 01) occurs, to prevent any abnormal situation caused by high voltage, setting of the flash
is changed automatically to disabling charge and flash setting.
After fixing, this setting needs to be deactivated. Flash error code can be initialized by the operations on the HOME screen.

Initializes the setting to the default setting. Even if you execute this function, the images 
stored in the internal memory are retained.

Camera

• If the imager has been replaced, carry out all the adjustments

for the camera section.

• As the imager may be damaged by static electricity from

its structure, handle it carefully like for the MOS IC.
In addition, ensure that the receiver is not covered with
dusts nor exposed to strong light.

The components identified by mark
