• This camera does not have a separate battery to power its clock. Clock settings are cleared whenever power to the camera is cut off (by batteries going dead while the camera is not connected to an AC power outlet with the AC adaptor) for about 24 hours. After power is resumed, either by loading fresh batteries or connecting to an AC power outlet, you will have to set the correct time and date again.
• The liquid crystal panel built into this camera is the product of precision engineering, with a pix el yield of 99.99%. This also means, however that 0.01% of the pixels can be expected to fail to light or to remain lit at all times.

1. PROGRAM LOADING

1-1. Important notice

Flash ROM on the D-PCB contains camera’s operating program and graphic menu. The D-PCB is used in the models QV-2300UX and QV -2800UX, how ever , the prog rams are different. Therefore, the PCB provided as a spare part cannot be discriminated which program is recorded. (Or old program may be recorded.)
Be sure to load the program after you replace the D-PCB.
Moreover, when you fail in updating the version of a program with CF card, a program breaks and a camera cannot be powered, please perform this method for loading program. (You can upgrade the program by this loading method.)
Note: If QV-2300UX program is loaded onto QV-2800UX, display indicates “NOT715 MOTOR” and the camera does not function.

1-2. To load the program

1. Tur n the camera off and remove the CF card then close the CF cover. Disconnect the battery and AC adaptor.
2. Connect the PC link cable.
3. Boot transferring program fload.exe.
4. Choose the program data “7romXXXX.bin.”
Notes:
*XXXX is 4-digit number depending upon the program version. *When loading file is chosen, “loaded XXXXXX bytes” is indicated on Status screen.
5. Choose the transfer speed 115K, 57K or 38K. If an error occurs, choose slower transfer speed.
6. Click Progress button on the fload.exe.
— 5 —
7. Connect an AC adaptor and turn the camera on within 5 seconds. Camera may be turned on automatically when an AC adaptor is connected. If not, use the power switch. Display shows “read time out” on Status screen and program data cannot be loaded if it takes too long between clicking Progress button and turning camera on.
8. Program data is transferred. Program executes Transfer, Erase, Program in order.
9. Program is loaded properly if Status screen shows “program completed”.
10. Disconnect the AC adaptor. (Power switch cannot turn the camera off.)
11. Choose graphic menu data “5gmenuXXXX.bin” on the above step 4 and perform steps 5 to 10.
12. Insert CF card.
13. While pressing down SHIFT and MENU keys, turn the power on to set the camera in test mode and check the version number.
14. Turn the camera off then on again and perform the final check by shooting, playing back and erasing.
Note:
In default, the COM Port 1 is set. If you wish to use other port, boot the camera by MS-DOS prompt. <example> fload 2 [ENTER]; this sets COM2 port.
