Power Supply

• Use only the special HR-3UA rechargeable nickel-metal hydride batteries to power this camera. Use of any other type of
battery is not supported.

• This camera does not have separate batteries for the clock. The date and time settings of the camera are cleared whenever
power is totally cut off (from both the batteries and AC adaptor). Be sure to reconfigure these settings after power is
interrupted.

LCD Panel

• The LCD panel is a product of the latest LCD manufacturing technology that provides a pixel yield of 99.99%. This means
that less than 0.01% of the total pixels are defective (they do not turn on or always remain turned on).

Lens

• You may sometimes notice some distortion in certain types of images, such as a slight bend in lines that should be straight.
This is due to the characteristics of lens, and does not indicate malfunction of the camera.

ADJ Tool

■ 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 "adj864.exe".
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 "adj864.exe2"

• 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 recognizes 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 1-2.(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 manufacturer'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.

— 8 —

NOTE: How to uninstall the USB driver for the USB test mode

• Connect the camera while in the USB test mode to the computer so that the computer recognises the
camera.

• Right-click "My computer", select "Property" and open "Device manager".

• Select "USB device for UUSBD" , and then "Universal USB Driver (VMEM manufacturer's name)".

• Press "Delete" button and delete the driver.

• When using Windows98/98SE/Me, delete the following three files;

(NOTE! Do NOT delete "usbd. inf" and "usbd.sys", whose names are much alike the following.)
C:windows / inf / uusbd.inf
C:windows / inf / other / KashiwanoUUSBD.inf
C:windows / system32 / drivers / uusbd.sys

• The driver has been successfully deleted.

1-4. Use the USB ADJ Tool

(1) Prepare ADJ data read/write tool "adj864.exe".
(2) Copy the common DLL for USB test to the same directory as that of the ADJ data read/write tool

"adj864.exe" or under "c:windows / system".

(3) Turn the camera power on which is set in the USB test mode and let it enter the USB test mode (the test

menu appears right after the power is turned on).
Connect the camera to the computer by the USB cable.

(4) Boot "adj864.exe" and use it as follows;

• Read ADJ data from the camera.  Press "read from the camera".

• Write ADJ data into the camera.  Press "write into the camera".

• Save ADJ data which is read.  Press "File" and "Save", and save it with an appropriate name.

• Open ADJ data which is saved.  Press "File" and "Open", and open the necessary file.

2. Connecting the TOOL
a) Place two 9-volt alkaline batteries in C2719.
b)

Connect the output terminal of C2719 to the channel terminal of the oscilloscope by the BNC-BNC cable.
c) Connect the input terminal to the Photo Diode by the BNC cable.
d) Turn the oscilloscope and C2719 on.

* Pull the ON/OFF switch of C2719 this way and raise/lower it. (See below Figure.)

3. Measurement
a) Connect S2281-01 to the camera’s LCD monitor (see below).

AC Waveforms appear on the monitor screen of the oscilloscope.
* Change the Rf range of C2719 in case the range does not match.

THE COUNTERMEASURE FOR "SYSTEM ERROR"

■ Purpose
System error may occur when the battery is removed while data is written to the internal memory.

If "SYSTEM ERROR" appears on the monitor, execute the following operation.

1. Back up the ADJ DATA.

2. Initialize the system.

3. Write the firmware.

4. Initialize the system again in order to initialize ADJ DATA.

5. Write the firmware again.

6. Return the backed up ADJ DATA.

7. Check the operation in the test mode.

■ PROCEDURE

1. Back up the ADJ DATA(Refer to the page 10 to 11).
a) Enter the TEST mode.

Turn the power on while pressing both "MENU"and "DISP" buttons.

Press "RIGHT" button, "RIGHT" button and "MENU" button.
b) Select "3.USB TCC TEST", and press "SET" button.
c) Select "1.USB TCC ON", and press "SET" button.
d) Turn the power OFF.
e) Connect the camera to the PC by the USB cable.
f ) Boot "adj864.exe".
g) Click "ADJ ALL READ", and display the data on the "adj864.exe".
h) Save the ADJ data.

Proceed to the next operation even if ADJ DATA cannot be saved.

2. Initialize the system.
a) Enter the TEST mode.
b) Select "7:ROM UPDATE" and press SET button.
c) Next, select "5:SYSTEM INITIAL" and press SET button.
d) The following message appears.

SYSTEM INITIALIZE
START
PUSH OK KEY?

e) Press SET button and System is initialized.

But the message, "SYSTEM ERROR", still appears on the monitor.

3. Write firmware.
Refer to the "How to update the firmware" on page 6.
Write the firmware.
If the TEST mode boots automatically, change "USB TCC ON" to "USB TCC OFF".

4. Initialize the system again.
Operation is the same as 2.
Proceed to the next operation even if "SYSTEM ERROR" appears on the monitor.

5. Write the firmware again.
Operation is the same as 3.

6. Return the backed up ADJ DATA.
a) Select "USB TCC ON".
b) Connect the camera to the PC by the USB cable.
c) Boot "adj864.exe".
d) Open the file which is saved above and display the data on the "adj864.exe".
e) Click "WRITE" button of "ADJ ALL".

7. Operation check
Boot TEST MODE.
Select "8:ADJ TEST" and press SET button.
a) When ADJ DATA can be backed up;

If both "3:AWB" and "6:KIZU" are OK, adjustment is completed.
In case "3:AWB" or "6:KIZU" is not OK, repeat the operation 2 and 3.

b) When ADJ DATA can not be backed up;

"AWB" and "KIZU" are "????".
Check the images in the REC mode and Play mode.
Adjustment is completed if the camera works properly.

After check, boot TEST mode again.
Select "3.USB TCC TEST", and press "SET" button.
Select "2.USB TCC OFF", and press "SET" button.

Replace the Main PCB if the camera does not recover.
