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 guidelines are based on the following battery types:
Alkaline: MX1500 (AA) DURACELL ULTRA
Lithium: Energizer
• Battery life varies with brand
• Figures are based on continuous recording under the following conditions.
Flash turned off
One zoom slider switching between T (Telephoto) and W (Wide-angle)
Regardless of use of the camera's flash, zoom function, turning on and off the POWER
Switch, as well as other operating conditions may aftect the above values.

*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 adapter) 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 an effective pixel rate 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 version upgrading
The program and the graphic menu are stored in the camera unit.
Confirm the version number of them, and if old version data are used, change them to the latest version.
For making an upgrade, two methods are available: with a CF card or with a PC link cable.
Notes:
(1) Make sure to use an AC adaptor.
In case the power is cut off during the program transmission or an error is occurred, the D-PCB will be
defective and unusable.
(2) Note that products with a mask ROM cannot be upgraded.
1-1 How to confirm the program (graphic menu) version
(1) Activate the TEST mode.
Turn on the power while pressing DISP and MENU keys.
(2) Confirm indications on the LCD monitor.
(Example of indications)

Set QV-8000SX to "PLAY" mode
1. Preparation
(1) Voltage regulator
(2) Ammeter
2. Adjustment procedure
(1) Apply 6.0 ±0.1 V voltage on DC in jack.
• Make sure that current consumption is less than 520 mA in PLAY mode.
• Make sure that current consumption is less than 690 mA in REC mode.
(Flash charge current is not included)
(2) Lower the voltage from 6 V as shown below then make sure the battey warning indicator changes.
DC in = 5.00 ±0.05 [V] (one indicator is off)
DC in = 4.65 ±0.05 [V] (two indicators are off)
DC in = 4.35 ±0.06 [V] (all indicators are off)

10-step gray scale
3-5. VCOM-DC Adjustment
1. Preparation
•AC adaptor or voltage regulator
•Photo sensor / photo sensor amplifier (C2719)/Low-Pass filter)
•Digital oscilloscope
2. Adjustment procedure
(1) Turn POWER on while pressing DISP key and MENU button simultaneously
(2) Quickly press keys in the order of FLASH key, FLASH key and MENU key.
(3) Select / Execute 50PERCENT GRAY.
(4) Monitor the photo sensor amplifier output via a low-pass filter of cutoff frequency 60Hz.
Monitoring the oscilloscope screen, adjust VR321 to minimize 60Hz ripple waveform.
3. Notes
Perform the adjustment after you replaced the LCD display module or L-PCB Assy.

2. Check matter
(1) Photography check (Please be sure to carry out.)
1Shoot the test chart without flashing.
2Shoot the test chart with flashing.
3Confirm the result (compare with properly functioning camera) for;
•Color
•Focus and resolution
(2) Shock resistance, Battery operation, AC adaptor operation.
(3) Slide switch, dial and button operations.
(4) Pivotal operation of the camera unit, CompactFlash insersion/eject operation, Cover open/close
operation, battery cover open/close operation.
(5) Resolution and color reproduction
(6) Image reversing, AE operation , AF operation, zoom operation, clock and screen saver functions.
(7) Video output, digital communication, USB function.
(8) Flash operation.
(9) Dust and scratches on lens.
(10) External inspection.
3. Notes
(1) Make sure Video out setting are appropriate to your country.
(i.e. Japan=NTSC, England = PAL)
