About the "InfoLITHIUM" battery pack

How to store the battery pack
•If the battery pack is not used for a long time, do the following procedure once per
year to maintain proper function.
1. Fully charge the battery.
2. Discharge on your electronic equipment.
3. Remove the battery from the equipment and store it in a dry, cool place.
•To use the battery pack up on your camcorder, leave your camcorder in the standby
mode until the power goes off without a cassette inserted.
Battery life
•The battery life is limited. Battery capacity drops little by little as you use it more and
more, and as time passes. When the available battery time is shortened considerably, a
probable cause is that the battery pack has reached the end of its life. Buy a new
battery pack.
•The battery life varies according to how it is stored and operating conditions and
environment for each battery pack.

About the "InfoLITHIUM" battery pack
What is the "InfoLITHIUM" battery pack?
The "InfoLITHIUM" battery pack is a lithium-ion battery pack that has functions for
communicating information related to operating conditions between your camcorder
and an AC adaptor/charger (optional).
The "InfoLITHIUM" battery pack calculates the power consumption according to the
operating conditions of your camcorder, and displays the remaining battery time in
minutes.
Charging the battery pack
•Be sure to charge the battery pack before you start using your camcorder.
•We recommend charging the battery pack in an ambient temperature of between
10°C to 30°C (50°F to 86°F) until the backlight of the display window goes out,
indicating that the battery pack is fully charged. If you charge the battery outside of
this temperature range, you may not be able to efficiently charge the battery pack.
•After charging is completed, either disconnect the cable from the DC IN jack on your
camcorder or remove the battery pack.
Effective use of the battery pack
•Battery pack performance decreases in low-temperature surroundings. So, the time
that the battery pack can be used is shorter in cold places. We recommend the
following to ensure longer battery pack use:
– Put the battery pack in a pocket to warm it up, and insert it in your camcorder
immediately before you start taking shots.
– Use the large-capacity battery pack (NP-FM70/QM71/FM90/FM91/QM91,
optional).
•Frequently using the LCD panel or frequently operating playback, fast-forward or
rewind wears out the battery pack faster. We recommend using the large-capacity
battery pack (NP-FM70/QM71/FM90/FM91/QM91, optional).
•Be sure to turn the POWER switch to OFF (CHG) when not taking shots or playing
back on your camcorder. The battery pack is also consumed when your camcorder is
in the standby mode or playback is paused.
•Have spare battery packs handy for two or three times the expected recording time,
and make a trial recordings before taking the actual recording.
•Do not expose the battery pack to water. The battery pack is not water-resistant.
Remaining battery time indicator
•If the power may go off although the remaining battery time indicator indicates that
the battery pack has enough power to operate, charge the battery pack fully again so
that the indication on the remaining battery time indicator is correct. Note, however,
that the correct battery indication sometimes will not be restored if it is used in high
temperatures for a long time or left in a fully charged state, or the battery pack is
frequently used. Regard the remaining battery time indication as the approximate
shooting time.
•The E mark indicating that there is little remaining battery time sometimes flashes
depending on the operating conditions or ambient temperature and environment even
if the remaining battery time is about five to 10 minutes.

About i.LINK

The DV jack on this unit is an i.LINK-compliant DV input/output jack. This section
describes the i.LINK standard and its features.
What is "i.LINK"?
i.LINK is a digital serial interface for handling digital video, digital audio and other
data in two directions between equipment having the i.LINK jack, and for controlling
other equipment.
i.LINK-compatible equipment can be connected by a single i.LINK cable. Possible
applications are operations and data transactions with various digital AV equipment.
When two or more i.LINK-compatible equipment are connected to this unit in a daisy
chain, operations and data transactions are possible with not only the equipment that
this unit is connected to but also with other devices via the directly connected
equipment.
Note, however, that the method of operation sometimes varies according to the
characteristics and specifications of the equipment to be connected, and that operations
and data transactions are sometimes not possible on some connected equipment.
Note
Normally, only one piece of equipment can be connected to this unit by the i.LINK
cable (DV cable). When connecting this unit to i.LINK-compatible equipment having
two or more i.LINK jacks (DV jacks), refer to the operating instructions of the
equipment to be connected.
About the name "i.LINK"
i.LINK is a more familiar term for IEEE 1394 data transport bus proposed by SONY,
and is a trademark approved by many corporations.
IEEE 1394 is an international standard standardized by the Institute of Electrical and
Electronic Engineers.
i.LINK baud rate
i.LINK's maximum baud rate varies according to the equipment. Three maximum baud
rates are defined:
S100 (approx. 100 Mbps*)
S200 (approx. 200 Mbps)
S400 (approx. 400 Mbps)
The baud rate is listed under "Specifications" in the operating instructions of each
equipment. It is also indicated near the i.LINK jack on some equipment.
The maximum baud rate of equipment on which it is not indicated such as this unit is
"S100".
When units are unit is connected to equipment having a different maximum baud rate,
the baud rate sometimes differs from the indicated baud rate.
* What is "Mbps"?
Mbps stands for megabits per second, or the amount of data that can be sent or received
in one second. For example, a baud rate of 100 Mbps means that 100 megabits of data
can be sent in one second.
