About Moisture Condensation

If the unit or cassette 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 a malfunction may occur.
When condensation occurs, the alarm messages
"% Z Moisture condensation. Eject the cassette" or
"% Moisture condensation. Turn off for 1H." will
appear.
Moisture condensation is likely to occur under the
following conditions:
• The unit or cassette is brought from the cold outdoors
to a warm indoor location.
• The unit or cassette 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 cassette 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
If moisture condensation occurs
Remove the cassette immediately. While the alarm
indicator is displayed, you cannot operate the unit
except to press the EJECT button.
Turn off the power and leave the front panel open until
the condensation disappears (approximately 1 hour). If
the alarm message does not appear when you turn on
the unit, and if % or Z does not flash when you insert
a cassette and press the video operation button, you
can use the unit again.
If there is negligible condensation in the unit, this
condensation may not be detected. In that case, the
cassette may not be ejected for approximately 10
seconds after you open the front panel. This is not a
malfunction. Do not close the front panel until the
cassette is ejected.

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
menu. 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 [HOURS METER]
of the [OTHERS] menu (See page 53).
• OPERATION mode
The cumulative total hours of operating time is
displayed in 10-hour increments.
• DRUM RUN 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.
