Canon 814XL-S - Manual (Page 22)

Checking the Batteries
A fresh set of batteries should provide sufficient
power to film seven sound cartridges or ten silent
cartridges when filming in normal temperatures.
The batteries should be checked at the fol­
lowing times:
1. After replacing the batteries.
2. After loading a new cartridge.
3. When using the camera after it has been left
idle for an extended period.
4. When filming in cold temperatures.
To check the power level, proceed as f ol lows:
1. Turn ON the main switch.
2. Press the battery check button. When this
button is pressed the meter needle of the
recording level/power level meter moves. The
position of the needle depends on the con­
dition of the batteries as indicated in the fol­
lowing chart whether the camera is loaded
with silent or sound cartridge.
