Pack - Sony handycam CCD-TR91 Operating Manual

This section shows you how you can get the most out of your battery pack.
Preparing the Battery Pack
Have Sufficient Battery Pack Power to Do 2 to 3 Times as much Recording as You have
Planned,
"Battery life" indicated in this manual is measured by the continuous recording time of the camcorder,
p_aced at room temperature using a fully-charged battery pack.
Battery Life is Shorter In Cold Environment
Battery efficiency is decreased and the battery will be used up more quickly if you are recording in a
cold environment.
To Save Battery Power
Turn STANDBY on the camcorder down when not recording to save battery power. (p. 9) [a]
A smooth transition between scenes can be made even if recording is stopped and started again. While
you are positioning the subject, selecting an angle, or looking through the viewfinder lens, the lens
moves automatically and the battery is used. The battery is also used when a tape is inserted or
removed.
_en to Replace the .affery Pack ................ _ _ ,_ _ _ _ _ _:
While you are using your camcorder, the remaining battery indicators in the viewfinder (1) and in the
display window (2) decrease gradually as battery power is used up.
(1)
(2)
When the remaining battery indicator reaches the lowest point, the _ indicator appears and starts
flashing in the viewfinder. (p. 9) [b]
When the _ indicator in the viewfinder changes from slow flashing to rapid flashing while you are
recording, slide the POWER switch to OFF on the camcorder and replace the battery pack. Leave the
tape in the camcorder to obtain a smooth transition between scenes after the battery pack is replaced.
Note on the remaining battery Indicator
The remaining battery indicator of the camcorder may indicate a different remaining capacity from that of
the NP-77HD battery pack (not supplied), The indicator of NP-77HD is more accurate.
The Battery Pack Heats Up
During charging or recording, the battery pack heats up. This is caused by energy that has been
generated and a chemical change that has occurred inside the battery pack. This is not cause for
concern.
Battery Pack Care
• Remove the battery pack from the camcorder after using the battery pack, and keep it in a cool place.
When the battery pack is attached to the camcorder, a small amount of current flows to the camcorder
even if the POWER switch is set to OFF, which shortens battery life.
• The battery pack is always discharging even when it is not in use after charging. Therefore, you
should charge the battery pack right before using the camcorder.
How to Use the Switch on the Battery Pack
This switch is provided so that you can mark the charged battery pack. Set the switch to the "no mark"
position when charging is completed. Set the switch to the "red mark" position when the battery is used
up (or in whichever direction you want to remind yourself). (p. 9) [c]
