PhotoPC 2100Z Revision E
Adjustment Adjustment 71
5.3.7 USB ID Writing
In this adjustment, the USB ID is written in flash memory on the Main Circuit Board.
When the Main Circuit Board has been replaced with a new one, the camera can not
use the USB ID which is stored on the old circuit board. Therefore, make this
adjustment to register a new USB ID on the new circuit board.
