Battery Life The values noted below indicate the number of hours before battery failure under normal operating

temperature (25°C). These values are for reference only , and do not guarantee that any particular
set of batteries actually will provide the service life indicated. Low temperatures shorten battery
life.

• The above figures are approximations only.

• The above guidelines are based on the following battery types:
Alkaline: MX1500 (AA) DURACELL ULTRA
Lithium: Energizer

• Battery life varies with brand.

Continuous recording values show the number of shots without using the flash. The number of
shots depends on use of the flash and whether flash is turned on or off.

Standard Accessories Strap; lens cap; cap holder; special USB cable; special video cable; four LR6 alkaline batteries;

Best Shot scene List

• 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 pixel 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-2400UX and QV-2900UX, however, the programs are dif ferent. 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-2400UX program is loaded onto QV-2900UX, display indicates “NOT715 MOTOR” and the
camera does not function.

1-2. T o load the program

1. Turn 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 “_romXXXX.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 “_gmenuXXXX.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.

5-4. Contrast and Brightness voltage setting adjustment

1. Preparation

•AC adaptor or voltage regulator

•Digital oscilloscope

2. Adjustment procedure

(1) Start up Test mode Menu1.

1. Turn POWER on while pressing SHIFT key and MENU button simultaneously

2. Quickly press keys in the order of SHIFT key, SHIFT key and MENU key.
(2) Select / Execute GRAY SCALE (10 step). (NTSC)
(3) Trigger VG waveform (CP322) by FRP (CP300) signal to adjust as noted below.
(4) Adjust CONTRAST VR (VR306) so that contrast terminal voltage(CP302) signal is 1.50 ± 0.05 V.
(5) Adjust BRIGHT VR (VR303) so that potential between signal’s pedestal and 4 step is 2.25 ± 0.05 Vp-p.
(6) Adjust CONTRAST VR (VR306) so that potential between signal’s pedestal and 10 step is 2.85 ± 0.05

Vp-p.

(7) Remove the resistance set between the killer terminal (CP308) and the VCC5 (CP520).

3. Notes

• Consecutively, execute 5-5. TINT setting adjustment.

• Make sure that waveforms are not distorted.
