Canon 814XL - Manual (Page 22)

Battery Loading
Both the drive system and the exposure metering
of this camera are powered by the same bat­
teries. Please make sure that the batteries are
loaded before filming. Four penlight (size AA)
batteries are used and are loaded into the grip.
1. Remove the battery compartment cover by
unscrewing it as shown by the arrow.
2. Follow the diagram on the side of the grip
when loading the batteries.
3. Replace the cover and tighten the screw.
When changing batteries, be sure to load new
batteries of the same brand and same kind at the
same time. Please be careful when loading them
because if they are loaded the wrong way, the
reversed polarities may damage the camera.
When filming in cold places, battery life will be
shortened so please take extra batteries with
you. The batteries must be kept warm before
shooting in such places. When you shoot in tem­
peratures below 0°C, Ni-Cd batteries are highly
recommended. When not using the camera for a
long period of time, take the batteries out to
avoid damage to the camera from leaky bat­
teries. When not filming please make sure to
switch off the camera to prevent battery waste.
