What is the "InfoLITHIUM" battery pack
The "InfbLITHIUM" battery pack is a lithium battery pack whicb can exchange data with
compatible video equipment about its battery consumption.
Sony recommends that you use the "InfoLITHIUM" battery pack with video equipment
having the ("1)IntoLITHIUM mark.
When you use tbis battery pack with video equipment having the (_1.) I nCoMTHIUM mark, the
video equipment will indicate the remaining battery time in minutes.*
* The indication may not be accurate depending on the condition and environment which
the equipment is used under.
How the battery consumption is displayed
The power consumption of the camcorder changes depending on its use, such as whether
the LCD is used or not, how the autofocusing is working on or not.
While checking the condition of the camcorder, the "InfloLITHIUM" battery pack measures
the barrelT consumption and calculates tbe remaining battery power. If tbe condition
changes & astically, the remaining battel T indication may suddenly decrease or increase by
more than 2 minutes.
Even if 5 to 10 minutes is indicated as the batte_T remaining time on the LCD or viewfinder,
the cNqldicator may also flash trader some conditions.
To obtain more accurate remaining battery indication
Set the camcorder to recording standby mode and point towards
a stationary
object. Do not
move the camcorder for 30 seconds or more.
• If the indication seems incorrecL use up the battery and then recharge it flflly (Frill
charge_)). Note that if you have used the battery in a hot or cold environment for long
time, or you have repeated charging many times, the battery may not be able to show the
correct time even after being fully charged.
• Af'.er you have used the "Infl_LITHIUM" battery pack with an equipment not having the
_1.)mcouruluMmark, make sure that you use up the battery on the equipment having the
_) InfoLITHIUM mark and then recharge f\flly.
Why the remaining battery indication does not match the continuous
recording time in the operating instruction
The recording time is affected by the envilonmental temperature and conditions. The
recording time becomes very short in a cold environment. The continuous recording time in
the operating instruction is measured under the condition of using a f\flly charged (or
normal charged 2))battery pack in 77 °F (25 °C). As the environmental temperature and
condition are diflbrent when you actually use the camcorder, the remaining battery time is
not same as the continuous recording time in the operating instruction.
_) Ftfll charge: Charging for about 1 hour after the charge lamp of the AC power adaptor
goes off.
2) Normal charge: Charging just tmtil the charge lamp of the AC power adaptor goes off.
