MEMORY RESET AND COLOR ADJUSTMENT
When the repairing or the following problems occured on QV-200, make the memory reset and the color adjustment as shown below.
A)After replacement of Digital PCB or Camera unit
B)Memory error
C)No display caused by Memory error
D)Color tone problem
MEMORY ERROR
"Memory error" (#1 ~ #4) message appears on QV-200 camera, when an error is found in its flash memory. In this case, the QV-200 is locked up and do not accept any operation except power on/off.
!
MEMORY ERROR
#1
CONSULT
THE OWNERíS MANUAL
It is required to reset the flash memory and adjust the color information.
NO DISPLAY CAUSED BY MEMORY ERROR
When the memory error occures, sometimes the display and back light do not work.
In this case, it is required the flash memory reset and color adjustment, same as the case of memory error.
COLOR TONE PROBLEM
In this case, do the color adjustment only.
REQUIRED TOOL
Light box: Handy 5000 (Code No.: 1904 5301) It used for QV-100 also.
Batteries for the light box: 4 × LR20 (D) size alkaline batteries
Color temperature filter (Code No.: 1904 5363): LA-120 (Orange)
ND filter (Code No.: 1904 5362): ND-50 (Grey)
Adjustment software: SDJ775A.EXE
QV-Link software: LK-10V (For VGA)
TO SOLVE THE PROBLEMS
MEMORY ERROR
1.Save the image (CAM files) of the QV-200 to PC by using QV-Link software.
*Although the memory error #1 and #2 occures, sometimes the image can be transfered to PC. The image transfer is impossible in the memory error #3 and #4.
2.Execute the memory reset and color adjustment by SDJ775A.EXE.
3.Reload the image to QV-200 by using QV-Link.
