Maintenance/Others

Cleaning the Video Heads

In the following cases the video heads
are dirty and need to be cleaned.
- The message "HEADS DIRTY, USE
CLEANING CASSETTE" appears.
- During playback you notice frequent
video problems (blocky video artifacts,
banding, etc.).
- When playing back a tape recorded in
HDV standard the playback is jerky or the
sound stutters on and off.
To maintain the best picture quality, we
recommend using cassettes designed for
high definition recording (Canon Digital
Videocassette HDVM-E63PR, etc.) and
cleaning the video heads frequently with
the Canon DVM-CL Digital Video Head
Cleaning Cassette or a commercially
available dry cleaning cassette.
Do not use wet type cleaning cassettes
as this may damage the camcorder.
Even after cleaning the video heads
you may not be able to play back
correctly tapes that were recorded with
dirty video heads.
Cleaning the Camcorder
Camcorder Body
Use a soft, dry cloth to clean the
camcorder body. Never use chemically
treated cloth or volatile solvents such as
paint thinner.
Lens and Viewfinder
If the lens surface is dirty, the autofocus
may not work properly.
Remove any dust or dirt particles using
a non-aerosol type blower brush.
Use a clean, soft lens-cleaning cloth to
gently wipe the lens or viewfinder. Never
use tissue paper.
LCD Screen and I.AF sensor
Clean the LCD screen and the I.AF
sensor using a clean, soft lens-cleaning
cloth.
Condensation may form on the surface
of the screen when the temperature
changes suddenly. Wipe it with a soft dry
cloth.
Storage
If you do not intend to use the
camcorder for a long time, store it in a
place free of dust, in low humidity, and at
temperatures not higher than 30 °C
(86 °F).
Condensation
Moving the camcorder rapidly between
hot and cold temperatures may cause
condensation (water droplets) to form on
its internal surfaces. Stop using the
camcorder if condensation is detected.
Continued use may damage the
camcorder.
Condensation may form in the following
cases:
When the camcorder is moved from an
air-conditioned room to a warm, humid
place
