PROGRAM VERSION UPGRADING
■ Introduction
Update the program using the memory card.
Note:
Make sure to use a fully charged battery.

1. How to confirm the program version
■ The program version can be confirmed in the test menu (refer to the previous page).
■ Turn the power on while pressing MENU button.
The following program version also can be found.
Check the LCD display.
(Example)
VER 1.00
(As of July 3. 2002)
2. How to update the firmware
1. Prepare the memory card which contains the software for upgrading firmware in the root directory.
qv-r3.bin (QV-R3)
qv-r4.bin (QV-R4)
2. Insert the above memory card into the camera, and set the AC adapter or a fully charged battery in the
camera.
3. While pressing MENU, press power switch. Keep pressing MENU until “PROGRAM UPDATE” appears
in the camera LCD
• The following appears.
• The version for the firmware update software in the memory card appears at the bottom.

MENU, and check the version.
VER 1.00
• “VER 1.00” appears this time.
7. If the version is correct, turn the power off.
8. Finally, check the operation by recording, playing back and deleting an image.
3. How to restore the firmware
1. Prepare the following firmware restoration program and change its name as follows;
kx861r.hbn mercury.bin (QV-R3)
kx862r.hbn mercury.bin (QV-R4)
2. Copy the above file to the root directory in the memory card.
3. Insert the memory card into the camera.
4. Set the AC adapter or a fully charged battery in the camera.
5. Turn the power on while pressing the shutter release button.
The LED next to the optical finder changes from green/red blinks green blinks/red lights only red
lights.
6. When only the red LED lights, the firmware restoration is finished.
Remove the AC adapter or the battery and turn the power off.
7. Turn the power on again while pressing MENU and DISP buttons.
The firmware is successfully restored if the corresponding version appears next to “PR” of the test
menu.
PR:02.07.03.21.47 (QV-R3)

ADJUSTMENT
■ Introduction
Make sure to perform the adjustment when replacing the lens unit or the MAIN PCB.
The necessary software, driver and setting are explained in using USB ADJ Tool "adj331e.exe (Ver.1.1).
Note that the tool, drivers etc. are available only for Windows.
1. How to use USB ADJ Tool
1-1. Prepare the necessary software, driver and DLL file.
(1) Prepare the following three files.
• Commom test driver for CASIO/PENTAX
[testmode_pentax_casio] folder uusbd.dll
uusbd.inf
uusbd.sys
• ADJ data read/write tool "adj331e.exe"
• Commom DLL for USB test "uusbd.dll"
(2) Place the commom test driver for CASIO/PENTAX in an appropriate place.
(3) After downloading the common DLL for USB test, copy it to the same directory as that of the ADJ data
read/write tool or under "c:windows/system.
1-2. Set the camera so that it recognises the USB test mode.
(1) Enter the test mode and then the initial test selection screen.
Turn the power on while pressing both "MENU" and "DISP".
Press "RIGHT", "RIGHT" and "MENU.
(2) Move the cursor to "3:USB TCC TEST" and press "SET".
(3) Move the cursor to "1:USB TCC ON" and press "SET".
(4) Press "MENU" button and leave the test mode.
(5) This enables the camera to recognise the USB test mode flag.
(6) When the USB test mode flag is ON, the test menu appears first when the camera power is turned on.
* If the USB test mode flag should be OFF, set "2: USB TCC OFF" in the test menu.
1-3. Install the USB driver for the USB test mode in the computer.
(The following is an example using the Windows Me.)
(1) Prepare the USB driver for the USB test mode.
(2) Turn the camera power on which is set in the USB test mode and let it enter the USB test mode as
shown in 2.(the test menu appears right after the power is turned on).
(3) Connect the camera in the above status to the computer by the USB cable.
(4) "A wizard for the new hardware" appears.
(5) Check "Designate the place for the driver (for users with sufficient knowledge)" and press "Next".
(6) Check "Search for the optimum driver for the device (recommended)".
(7) Check "Designate the place to search" , designate the place which contains "inf" file in the driver by
pressing "Reference" button, and then press "Next" button.
(8) When "Universal USB Driver (VMEM manufacturer's name)" appears upon message "Searching for
the driver file for the following devices" , press "Next" button.
(9) The file copy starts.
(If a message "uusbd.Inf cannot be found" appears during the file copy, designate the same place as in
the step 7).
(10) Press "Complete" button.
(11) Right-click "My computer", select "Property" and open "Device manager". If "Universal USB Driver
(VMEM manufactur's name)" can be found in "USB device for UUSBD", the computer has successfully
recognised the driver.
(12) The test driver can be used for both CASIO/PENTAX. Installing the test driver into either one enables
the other one to recognise it.
