Flexible Board
• Make sure that the conductive side of a flexible board does not have any stain or foreign materials.
• Do not touch the conductive side of flexible boards with bare hands.
• Plug in a flexible board straight, fully into the connector until it reaches the end inside.

Fine-Wire Coaxial Cable
• The proper way to disconnect a connector is to grab the connector instead of the wires. If you pull on the wires,
they might be broken.

Discharging of the Flash Capacitor
The charging capacitor for the flash has been charged at high voltage. Therefore, there is a possibility of an electric
shock if you directly handle this capacitor.
The high-voltage charge will not be discharged by simply turning off the unit’s power. Make sure any remaining voltage
is discharged by short-circuiting the flash capacitor with a Short Jig.

The high-voltage charge will not be discharged by simply turning off the unit’s power. Make sure any remaining voltage
is discharged by short-circuiting the flash capacitor with a Short Jig.
Preparing the Short Jig
Make a Short Jig by connecting a small clip to each lead of a resistor with a rated value of approximately 1 kΩ/1 W.
In order to prevent an electric shock, wrap insulating tape completely around the resistor and its leads.

Precaution on Replacing the SY-1056 Board
The board for repair is not recorded the information unique to a model. Therefore the following data are needed to write.
Note
The [LOAD AND WRITE] function in “ADJUSTMENT DATA BACKUP” on the DATA tab in the Adjust Manual
overwrites all data of the unit. Therefore execute the [LOAD AND WRITE] before performing the following operation.

Destination Data
The destination data stored in the repairing board is different from the destination setting stored in the board before
replacement in some cases.
When the board has been replaced with a repairing board, be sure to set the destination.

USB Serial No. and Product ID
The unit is shipped after an ID (USB Serial No.) unique to each unit and an ID (Product ID) unique to each model have
been written.
These IDs have not been written in a new repairing board. Therefore, after the board has been replaced, be sure to write
these IDs to a new repairing board.

Update of MAC Address
When a board that contains Wi-Fi has been replaced or when replacing a board that contains the main IC (CPU), the
IC’s unique number (MAC address) must be reloaded.

Note
After the replacement and repair, the MAC address is changed, and thus the re-setting for connection devices is required.
Accordingly, download the Flyer of WLAN Reset (Flyer of WLAN Reset_9834752[][].pdf) and print out it, and attach
