Notes on the video cassettes
If the cassette memory function does not work
Reinsert the cassette a few times. The terminal portion
of the cassette may be dusty or dirty.
Cleaning the terminal
If the terminal of the cassette gets dirty, or dust sticks
to the terminal, the unit may not work correctly.
Clean the terminal with the swab once every ten times
you eject a cassette.
When affixing a label to the cassette
Be sure to affix a label on only the correct location so
as not to cause malfunction of the unit.
After using a cassette
After use, please be sure to rewind the tape completely
(to prevent picture and sound distortion). Return it to
its case and store it in an upright position.
About moisture condensation
If the unit or tape is brought directly from a cold to a
warm location, moisture may condense inside or
outside the unit or tape. If you use the tape or video
heads in this condition, the tape may adhere to the
head drum, and the video heads or the tape may be
damaged, or malfunction may occur.
Moisture condensation is likely to occur under the
following conditions:
• The unit or tape is brought from the cold outdoors to
a warm indoor location.
• The unit or tape is brought from the air-conditioned
indoors to the hot outdoors.
• The unit is used in a place subject to cold currents
from an air conditioner.
When bringing the unit or tape from a cold place to a
warm place or vice versa, put it in a plastic bag and
seal the bag tightly. After bringing it into the new
place, leave the bag on for more than one hour, and
remove the bag when the air temperature inside it has
reached the temperature surrounding it.
If moisture condensation occurred
You cannot operate the unit except to press EJECT,
and the cassette cannot be inserted. If this occurs, turn
on the power to remove the cassette, then keep
opening the cassette lid, and finally wait more than one
hour for the moisture to evaporate.
Digital hours meter
The digital hours meter keeps cumulative counts of the
total operation time, the head drum rotation time, the
tape running time and the number of unthreading
operations. These counts can be displayed on the
monitor screen. Use them as guidelines for scheduling
maintenance.
In general, consult your Sony dealer about necessary
periodic maintenance checks.
The digital hours meter has the following four display
modes and you can check them in HRS METER of the
OTHERS menu (See page 92 (GB)).
•
OPERATION mode
The cumulative total hours of operating time is
displayed in 10-hour increments.
•
DRUM ROTATION mode
The cumulative total hours of drum rotation with tape
threaded is displayed in 10-hour increments.
•
TAPE RUN mode
The cumulative total hours of tape running time is
displayed in 10-hour increments.
•
THREADING mode
The cumulative number of tape unthreading
operations is displayed in 10-operation increments.
