Built-in Rechargeable Lithium Battery
The camcorder has a built-in rechargeable lithium battery to keep the date/time and other settings. The
built-in lithium battery is recharged while you use the camcorder; however, it will become totally
discharged if you do not use the camcorder for about 3 months.
To recharge the built-in lithium battery:
Connect the compact power adapter to the camcorder and leave it connected for 24 hours with the
camcorder off.
Video Heads
When the message “HEADS DIRTY, USE CLEANING CASSETTE” appears, when the playback
picture becomes distorted, or if during playback of a tape recorded in HDV standard the picture
and/or sound stops momentarily (about 0.5 seconds) the video heads need to be cleaned.
To maintain the best picture quality, we recommend cleaning the video heads frequently with the
Canon DVM-CL Digital Video Head Cleaning Cassette or a commercially available dry cleaning
cassette.
Tapes already recorded with dirty video heads may not be played back correctly even after cleaning
the video heads.
Do not use wet type cleaning cassettes as this may damage the camcorder.
If the playback picture does not improve after cleaning the video heads it may indicate a malfunction.
Consult a Canon Service Center.
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
When the camcorder is moved from a cold place to a warm room
When the camcorder is left in a humid room
When a cold room is heated rapidly
How to avoid condensation:
Unload the cassette, place the camcorder in an airtight plastic bag and let it adjust to temperature
changes slowly before removing it from the bag.
When condensation is detected:
The camcorder stops operating, and the warning message “CONDENSATION HAS BEEN
DETECTED” appears for approx. 4 seconds and starts flashing.
If a cassette is loaded, the warning message “CONDENSATION HAS BEEN DETECTED REMOVE
THE CASSETTE” appears and starts flashing. Remove the cassette immediately and leave the
cassette compartment open. Leaving the cassette in the camcorder may damage the tape.
A cassette cannot be loaded when condensation is detected.
