RESETTING THE PLACE OF DESTINATION
When the main PCB is replaced, the setting of the destination will be changed, therefore resetting is required.
However, when the firmware is changed or fixed, the setting of the destination will be held, therefore resetting
is not required.
Use the destination setting script to change the destination flag as instructed below.
1. Have an SD card ready that have a corresponding script (autorun.scp) under the root directory.
2. Insert the SD card in the camera and turn on the power.
The script is located at Qv/soft/Adj_soft/exz850/Script in the service CD-ROM.
3. After a few seconds, one of the following messages will be shown in the screen.
The system will change the destination flag and turn off the camera automatically.
