DSC-H1

The charging capacitor of the FLASH unit is charged up to the
maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
capacitor is handled by hand.  The electric shock is caused by the
charged voltage which is kept without discharging when the main
power of the DSC-H1 is simply turned off.  Therefore, the remaining
voltage must be discharged as described below.

To preparing the short jig. a small clip is attached to each end of a
resistor of 1 k

Ω

 /1 W (1-215-869-11)

Wrap insulating tape fully around the leads of the resistor to prevent
electrical shock.

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

When replacing the SY-127 board, erase the data in internal memory of the board before replacement.

When replacing the SY-127 board or the IC381 on the SY-127 board, execute formatting and initialize the internal memory after 
replacement.

Copies all images in the internal memory to a “Memory Stick”.

1

Insert a “Memory Stick” having 32 MB or larger capacity.

2

Select [OK] with v on the control button, then press z.
The message “All data in internal memory will be copied Ready?” appears.

3

Select [OK] with v , then press z.
Copying starts. 

Use batteries with enough capacity or the AC Adaptor (not supplied). If you attempt to copy image files 
using batteries with little remaining capacity, the batteries 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” after copying, then execute the [Format] command in 

 

Internal Memory Tool.
You cannot select a folder copied on a “Memory Stick”.
The setting of 

 (Print order) marks is not copied even when you copy data.

OK

See the following procedure.

Cancel

Cancels the copying.

Formats the internal memory.

Note that formatting irrevocably erases all data in the internal memory, including even protected images.

1

Select [OK] with v on the control button, then press z.
The message “All data in internal memory will be erased Ready?” appears.

2

Select [OK] with v, then press z.
The format is complete.

OK

See the following procedure.

Cancel

Cancels the formatting.

When “FLASH error”  (Self-diagnosis Code  E : 91 : ** ) 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 Setup screen.

Initializes the setting to the default setting.

1

Select [OK] with v on the control button, then press z.
The message “Initialize all settings Ready?” appears.

2

Select [OK] with v, then press z.
The settings are reset to the default setting.

Make sure that the power is not disconnected during resetting.

OK

See the following procedure.

Cancel

Cancels the resetting.
