6-2 Maintenance
6-2-1 Condensation
The water vapor in the air may form as tiny droplets on the
head drum when the unit is moved from a cold location to a
warm location or used in a very humid place. This
phenomenon is known as condensation, and running the
tape under these conditions is liable to cause the tape to
stick to the drum.
Note the following points:
≥Remove the tape when the unit’s operation is to be started
in conditions where condensation may form.
≥Before loading the tape, set the power switch to ON, and
check that the HUMID display is not lighted in the display
window.
<Note>
For safety reasons, the HUMID display will flash and the
drum will rotate for 80 minutes after condensation detection
is released.
During this time, the operation buttons cannot be operated.
6-2-2 Head cleaning
Use the AJ-CL12MP cleaning cassette if the heads need to
be cleaned. Take care to read the instructions
accompanying the cleaning tape since the video heads may
be damaged if the tape is not used in the correct way.
6-2-3
Cleaning inside the viewfinder
≥Do not use thinners or any other solvent to remove dirt.
≥Use a lens cleaner available on the market to wipe the
lens.
≥NEVER wipe the mirror.
If dirt or dust has found its way onto the mirror, remove it
using an air blower at retail outlets.
6-2-4 Phenomena inherent to CCD
cameras
Smear
This phenomenon may occur when very bright subjects are
shot.
This phenomenon is more conspicuous when the electronic
shutter speed is faster.
White dot defects
For shooting in a high temperature environment using the DS
GAIN, red, green, or blue dots may appear on the screen.
Adjust the DS. GAIN and the S. GAIN in accordance with the
operating environment.
6-2-5
Replacing the backup battery
The backup battery is already installed when the unit is
shipped.
When it has discharged, the “BACK UP BATT EMPTY”
display appears for 3 seconds on the viewfinder screen when
the POWER switch is set to ON.
Moreover, the time code value of the TCG will be set to
“00:00:00:00” and the backup of the time code value will no
longer be possible: this means that the backup battery
should be replaced.
Consult with your dealer, and replace the spent battery with
a new battery (CR2032).
