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.

Type of Operation

AA-size Alkaline
Batteries LR6
AA-size Lithium
Batteries FR6
AA-size Ni-MH Batteries
NP-H3

• 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.

Power Consumption Approximately 6.8 W
Dimensions 118(W) x 74.5(H) x 64.5(D) mm
Weight Approximately 355 g (excluding batteries)

• 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.

Please check the version and update it if the version is not updated.
There are two method of program updating; using CompactFlash card or utilizing PC link cable.

Note:
Be sure to use AC adaptor.

1-2. Upgrading procedure using the CompactFlash card

(1) Prepare a CF card that contain QV -4000 firmware upgrading software (qv-4000.bin) in the root directory.
(2) Insert the CF card in the QV-4000 and connect AC adaptor.
(3) While pressing the control button, turn the power key on to "PLAY".

The following display comes out.
Version display (VER1.00 etc.) may come out on the bottom of the display.

PROGRAM UPDA TE

YES
NO

(4) Moving the contol button up or down, move the white cursor at "YES" then push "SHUTTER" key.

The following display comes out and rewriting firmware starts.

NOW LOADING

(5) After a while, display shows “COMPLETE!” and the camera is set in PLAY mode.
(6) Turn the camera off then turn the power key to “PLAY” while pressing the control button.

Check the version number on the display.

PROGRAM UPDA TE

YES
NO

VER1.01

This time “VER1.01” will be shown.

(7) If the version number is correct, the firmware upgrading is completed.

Turn the camera off.

(8) Take a test picture.

Take one picture and play it back and check the result.
If the picture is normal, delete it and complete the test.

— 6 —

1-3. Upgrading procedure using the PC link cable

The restoration method at the time of firmware upgrade failure

(1) Set CD-ROM for Service Disc into CD-ROM drive of a personal computer and boot FLASH LOADER

“Fload.exe” then select a file to be transferred.
The transmission files are “romXXXX XXXX.bin” and “gmenuXXXX XXXX.bin”.
Perform file selection and rewriting one by one.
If a transmission file is chosen, “loaded ***** bytes” is shown on the “Status” column of the display.

(2) Extract CF card from the camera unit.
(3) Connect the QV serial cable between the camera and the PC.
(4) Click “Progress” button on FLASH LOADER “Fload.exe” of the PC.

At this time, keep the camera’s power off.

(5) Insert an AC adaptor and turn the power on.

Since the software is damaged in most cases therefore power turns on as soon as AC adaptor is
connected. In such a case, operation checking LED turns on in green so it does not matter even the
power key is off.
In case power does not turn on (operation checking LED does not turn on in green) when AC adaptor
is connected, turn the power key to “PLAY”.

(6) The progress bar on FLASH LOADER “Fload.exe” starts to move.

The progress bar proceeds to “Transfer”, “Erase” then “Program”.
If a camera has not been turned on for a long time after clicking the “Progress” button, “read timeout” is
shown on “Status” column and writing is not be done.
In such a case, repeat the procedures from step 1.

— 7 —

(7) If writing is completed, “program complete” will be shown on “Status” column of the display.

(8) Disconnect AC adapter and shut off a power supply.

This method does not turn the power off by key operation.
Therefore, disconnect the AC adaptor to shut the camera off compulsorily.

(9) Continuously choose and rewrite the other transmission file.

Repeat the above steps 1 to 8 to rewrite.

(10) When both files are rewritten, disconnect QV serial cable from the camera and check the version

indication following the undermentioned procedure.
While pushing down “DISP” and “MENU” keys, turn the power key to “PLAY” and check the version
numbers of Program and GMENU.

(11) After checking the version numbers, take one test picture and make sure that shooting, playing back,

and deleting are done normally.
