I Condensation
If excessive moisture condenses in the unit, [DEW
DETECTED] Indication wiil fiash, and the Paimcorder wiil
automaticaliy turn off after about 1 minute.
In this case, follow the steps beiow:
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 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 Palmcorder and
check to see if the [DEW DETECTED] Indication
is displayed.
• Even if the [DEW DETECTED] indication is not
displayed, as a precaution, please wait for another
hour before using the Paimcorder.
Watch for Condensation Even Before the [DEW
DETECTED] Indication Is Displayed.
• Because condensation takes place gradually, the [DEW
DETECTED] Indication may not be displayed during the
first 10 to 15 minutes of condensation formation inside the
Palmcorder.
• 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
Palmcorder in this condition for about 1 hour. When the lens
temperature becomes close to the ambient temperature, the
fog disappears naturally.
H Digital Video Head Cleaner
If the heads (the parts that make contact with tape) are dirty,
mosaic-like noise patterns 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 Palmcorder cannot record at all.
Causes of Digital Video 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 Palmcorder in
the same manner as a Video Cassette.
2 Press the [^] Button, and 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 stilt 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 Palmcorder needs to be cleaned at a service center.
Please consult a distributor.
• Video head cleaners can be purchased from service
centers.
• 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.)
I Optimal Use of the Battery
Battery Characteristics
This Battery is a chargeable 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 ot 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 Palmcorder. (If it is
left attached to the Palmcorder, a minute amount of current
is consumed even when the Palmcorder power is off.) If the
Battery is left attached to the Palmcorder for a tong 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 Palmcorder or AC
Adaptor may damage the Palmcorder or AC Adaptor.
