Optimal Use Of The Battery - Panasonic NV-EX21EG Operating Instructions Manual

ª Condensation
If the Condensation Indication flashes after the Movie
Camera is turned on, condensation has formed inside the
Movie Camera. In this case, the Movie Camera power is
turned off automatically after about 1 minute.
Follow the steps below:
1
Take out the Cassette.
≥None of the other functions operate. Depending on the
amount of condensation, removing the Cassette may
even become difficult. If this happens, wait for
2 to 3 hours before taking the Cassette out.
2
Open the Cassette Compartment Cover and
wait for 2 to 3 hours.
≥The number of hours to wait depends on the amount of
condensation and ambient temperature.
3
2 to 3 hours later, turn on the Movie Camera
power and check to see if the Condensation
Indication is displayed.
≥Even if the Condensation Indication is not displayed,
as a precaution, please wait for another hour before
using the Movie Camera.
Watch for Condensation even before the Condensation
Indication is displayed.
≥Because condensation takes place gradually, the
Condensation Indication may not be displayed during the
first 10 to 15 minutes of condensation formation inside the
Movie Camera.
≥In extremely cold places, condensation may freeze and
form frost. In this case, the frost melts first, thus forming
condensation, and then it takes another 2 to 3 hours to
eliminate the condensation.
When the Lens is Fogged:
Set the [OFF/ON/MODE] Switch to [OFF] and leave the
Movie Camera in this condition for about 1 hour. When the
lens temperature becomes close to the ambient
temperature, the fog disappears naturally.
ª Video Head Clogging and Care
If the heads (the parts that make contact with tape) are dirty,
mosaic-pattern noise may appear on the playback image, or
the screen as a whole becomes black. If the heads are
extremely dirty, recording performance deteriorates, and, in
the worst case, the Movie Camera cannot record at all.
Causes of Dirty Heads
≥Large quantity of dust in the air
≥High-temperature and high-humidity environment
≥Damaged tape
≥Long operating hours
Using Mini-DV Format Digital Video Head Cleaner
1
Insert the Head Cleaner into the Movie Camera
in the same manner as a Video Cassette.
2
Press the [1] Button, and approximately 20
seconds later, press the [∫] Button. (Do not
rewind the tape.)
3
Take out the Head Cleaner. Insert a Video
Cassette and start recording. Then, play the
tape back to check the recorded image.
4
If the image is not still clear, repeat Steps 1 to
3. (Do not use the Head Cleaner for 3 times or
more consecutively.)
Notes:
≥Do not rewind every time you use the Head Cleaner.
Rewind only when the tape reaches the end, and then use
it again from the beginning in the same manner as before.
≥If the heads become dirty soon after cleaning, the tape may
be damaged. In this case, immediately stop using that
Cassette.
≥Do not clean the heads excessively. (Excessive cleaning
may cause excessive wear of the heads. If the heads are
worn, images cannot be played back even after the heads
are cleaned.)
≥If the dirty heads cannot be cleaned with the Head Cleaner,
the Movie Camera needs to be cleaned at a service centre.
Please consult a dealer.
≥Video Head Cleaners can be purchased from service
centres.
≥Head cleaning due to dirty heads is not considered a
malfunction of the product. It is not covered by the
warranty.
Periodical Check-up
To maintain the highest image quality, we recommend
replacement of worn parts, such as heads, etc., after
approximately 1000 hours of use. (This, however, depends
on operating conditions, such as temperature, humidity,
dust, etc.)
ª Optimal Use of the Battery
Battery Characteristics
This Battery is a rechargeable lithium ion battery. Its ability to
generate power is based upon the chemical reaction that
takes place inside it. This reaction is susceptible to the
surrounding temperature and humidity, and, if the
temperature is too high or too low, the operating time of the
Battery becomes shorter. If the Battery is used in an
extremely cold environment, the Battery may operate only
for about 5 minutes. If the Battery becomes extremely hot, a
protective function may operate, and the Battery may
become unusable for a while.
Be Sure to Detach the Battery after Use
Be sure to detach the Battery from the Movie Camera. (If it is
left attached to the Movie Camera, a minute amount of
current is consumed even when the Movie Camera power is
off.) If the Battery is left attached to the Movie Camera for a
long time, over discharge takes place. The Battery may
become unusable after it is charged.
Disposing of an Unusable Battery
≥The Battery has a limited life.
≥Do not throw the Battery into fire because it may cause an
explosion.
Always Keep the Terminals of the Battery Clean
Prevent the terminals from getting clogged with dirt, dust, or
other substances.
If you drop the Battery accidentally, check to see if the
Battery body and terminals are deformed.
Attaching a deformed Battery to the Movie Camera or AC
Adaptor may damage the Movie Camera or AC Adaptor.
