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

Continuous Playback

Continuous Recording

• 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 6.6W Dimensions 129.5(W) x 75(H) x 61(D) mm (5.1˝ (W) x 2.9˝ (H) x 2.4˝ (D)) Weight Approximately 315g (11.1oz) (excluding batteries) Standard Accessories Strap; soft case; USB cable; video cable; User’s Manual

•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 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.

AA-size Alkaline Batteries LR6

1. Summary

(1) QV-2000UX is a high quality digital camera and makeshift adjustments cannot cover the quality of the

camera's picture. Therefore, we have prepared set of lens ass'y that is adjusted precisely in the factory and a floppy disc containing the lens'es adjustment data as spare parts.

(2) These adjustment data are stored in the EEPROM on PCB D.

2. Repairs

It is necessary to write color adjustment data for the replacements of the following units.

(1) Lens ass'y

(2) PCB D (when EEPROM contents can be read)

(3) PDB D and lens ass'y (when EEPROM contents cannot be read)

3. To replace the lens ass'y

(1) Connect AC adaptor and PC link cable to the camera.

Note: Connect the link cable to serial port COM1. (2) Turn the camera on to set it on PLAY mode. (3) Boot adjustment program ADJ713.EXE.
