Cleaning The Video Heads; Maintenance Cautions - Panasonic AG-DVC30 Operating Instructions Manual

Cleaning the video heads

When the video heads are dirty, mosaic-like
noise will appear here and there when tapes are
played back and/or a bluish tone will permeate
entire images.
Very dirty heads cause a deterioration in the
recording capability and at worst, they will make
it impossible to record altogether.
Factors that make the heads dirty
O High concentrations
atmosphere
O High-temperature
environments
O Tape damage
O Prolonged use
Use a cleaning cassette tape!
1 Insert a cleaning tape into the camera-
recorder and set the POWER lever to the ON
position.
2 Turn the POWER lever to the MODE
position, and check that the VCR lamp has
lit.
3 Press the 1 button, then ten seconds later
press the $ button.
(Do not rewind the tape at this time.)
4 Remove the cleaning tape, proceed with
recording and playback as a trial on another
tape and check the resulting images.
5 If the images are not clear, repeat steps 1 to
4.
(Do not use the cleaning tape more than 4
times in one go.)

Maintenance cautions

Do not use benzine or paint thinners for maintenance purposes.
O Using benzine or paint thinners may deform the camera-recorder and/or cause the surface finish
to peel off.
O Before proceeding with maintenance, remove the battery or disconnect the AC cord from the
power outlet.
O Use a soft, clean cloth to wipe the camera-recorder. To remove stubborn dirt, wipe the camera-
recorder with a cloth moistened with kitchen detergent that has been diluted with water and then
use a dry cloth to take up the remaining moisture.

of dust in the
and high-humidity
O Do not rewind the cleaning tape at any
interim point while it is playing. When it
reaches the end, rewind it and use it again in
the same way from the start.
O If the heads become dirty again immediately
after they have been cleaned, it may mean
that the condition of cleaning tape itself has
deteriorated. Stop
immediately.
O Excessive use of cleaning tapes will result in
head wear. When the heads are worn,
images will not be played back clearly even
immediately after the heads have been
cleaned.
O If the dirty heads do not become any cleaner
even when a cleaning tape is used, you will
need to have your dealer arrange for your
camera-recorder to be cleaned and/or
repaired. Consult your dealer if this happens.
Periodic inspections
To ensure that you will be able to view good-
quality images, it is recommended that you
replace the video heads and any other worn
parts every 2,000 hours or so of use.
(However, this period will differ significantly
depending on the temperature, humidity, dust
and other factors in the operating environment.)
