Canon 814XL-S - Manual (Page 18)

Grip
The camera's foldable grip doubles as a battery
compartment. Stored in the upward position,
it should be lowered for shooting. To lower it,
swing it downward, while pushing the grip
release in the direction of the arrow, until it stops
and locks into position. You should slide your
right fingers under the grip band while shooting.
Adjust the grip band to the most comfortable
length for you. To fold the grip back up, push the
grip release again.
Lens Cap
The lens is provided with a front cap which can
be attached and removed by pressing in the tabs
on both sides of the cap. To protect the lens, this
cap should always be attached when not filming.
Loading the Batteries
This camera will not function without batteries.
Since it is controlled electronically, batteries
power all systems, including film drive, the
recording mechanism and exposure control. Use
six AA-size 1.5V (penlight) alkaline manganese,
carbon zinc or Ni-Cd batteries. Wipe battery
poles with a clean, dry cloth before insertion to
avoid possible corrosion to contacts due to dirt
or fingerprints.
