Chapter 7 Maintenance
Notes on Use
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
You cannot operate the unit except to press EJECT,
and a cassette cannot be inserted. If this occurs, with
the unit powered on, remove the cassette, then 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
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 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 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.
Self-diagnostics Function
The unit has a self-diagnostics display function.
This function displays the current condition of the unit
as a five-digit code (a combination of a letter and
numbers), on the LCD monitor, display window, and
MONITOR VIDEO output. If a five-digit code is
displayed, check the following code chart. The last two
digits (indicated by ss) will differ depending on the
state of your unit.
If you are unable to resolve the problem, or a code
other than those in the above chart appears, contact
your Sony dealer or local authorized Sony service
facility and inform them of the number.
