Power Consumption Approximately 6.4 W
Standard Battery Life This camera can be power using AA-size alkaline, lithium or Ni-MH batter-
DIGITAL OUT, VIDEO OUT, AC adaptor connector, memory card connector
Four batteries (AA-size alkaline, lithium or Ni-MH batteries)/AC adaptor (AD-C620)
ies. The battery life reference values given below indicate the amount of
time at standard temperature (25°C) until power automatically turns off due
to battery failure. They do not guarantee that batteries will perform the amount
of service indicated. Battery life is reduced by low temperatures and contin-
ued use.
Continuous Playback: Alkaline Batteries (LR6); Approx.180 minutes
Lithium Batteries (FR6); Approx. 290 minutes
AA-size Ni-MH; Approx.170 minutes
Continuous Recording: Alkaline Batteries (LR6); Approx. 630 shots
Lithium Batteries (FR6); Approx. 1,200 shots
AA-size Ni-MH; Approx. 780 minutes
•The above figures are approximations only.
•The above guidelines are based on the following battery types:
Alkaline: MX1500 (AA) DURACELL ULTRA
Lithium: Energizer
Ni-MH (Nickel-Metal Hydride): CASIO NP-H3
•Battery life varies with brand.
“Continuous Recording” is made without use of the camera’s flash.
Regardless of use of the camera’s flash, turning on and off the POWER
Switch, as well as other operating conditions may affect the above values.

DISASSEMBLY
The following explains the disassembly procedure of QV-780. Numbers in the procedures correspond to the
part numbers on the exploded view.
Assembly can be done by the reverse order.
1. Remove the CompactFlash card by pushing the release lever.
2. Remove two screws j from the bottom of the camera.
3. Unscrew two screws f from the lens side of the case.
Note:Turn the lens as screws f are hidden by the Camera unit 1.
4. Remove three screws h and one screw i from the CompactFlash card compartment.
Note: Screw i is longer than the others. Do not misplace it when you assemble the camera.
