Whatisan "InfoLITHIUM"battery pack?
All "InfoLITHIUM" battery pack is a lithium-ion battery pack that has
functions for exchanging information related to operating conditions with
your camera.
Neles
• The displayed level may not be correct under certain circmnstances.
• Do not expose the battery pack to water. The battery pack is not water-resistant.
• Do not leave the battery pack in extremely hot places, such as in a cal"or under direct
sunlight.
Available battery packs
Only an NP-FH50 battery pack can be used with the camera. Note that the
NP-FH30 and NP-FH40 cannot be used.
Effective useof the battery pack
• Battery performance decreases in low temperature surrouudiugs. So, the
time that the battery pack can be used is shorter in cold places and the
speed of continuous shooting slows down. We recommend that you put
the battery pack in a pocket close to your body to warm it up, and insert it
in your camera immediately before you start shooting.
• The battery pack will run out quickly if you use the flash frequently, use
continuous shooting often, or turn the camera on and off frequently.
• The time available in the Live View' mode is shorter than that in the
viewfiuder mode. When you feel that the battery consumption is too fast,
switch to the viewfiuder mode. Doing so makes the battery last longer.
Battery life
• The battery life is limited. Battery capacity decreases little by little as you
use it more and more, and as time passes. If the battery operating time
seems shortened considerably, a probable cause is that the battery pack
has reached the end of its life. Buy a new battery pack.
