Condensation
If you move the unit suddenly from a cold to a warm
location, or if you use it in a very humid place, moisture
from the air may condense on the head drum. This is called
condensation, and if a tape is run in this state, the tape may
stick to the drum and can be easily damaged. To lessen the
risk of this occurring, this unit is equipped with a
condensation detection system.
If condensation occurs while the unit is
operating:
The alarm message “MOISTURE HAS BEEN
DETECTED.” appears on the monitor screen, and the
alarm message “HUMID!” in the time counter display. At
the same time the unit ejects the cassette automatically. If
this happens, leave the unit powered on and wait until the
alarm messages disappear.
If the condensation alarm message appears
immediately after powering on:
Leave the unit powered on and wait until the alarm
message disappears. You cannot load a cassette into the
unit while the alarm message is being displayed.
Once the alarm message disappears, the unit is ready for
use.
Regular Checks
Digital hours meter
The digital hours meter keeps cumulative counts of the
total operating time, the head drum rotation time, the tape
transport operating time, and the number of threading/
unthreading operations. These counts can be displayed on
the monitor screen and in the time counter display of this
unit. Use them as guidelines for scheduling maintenance.
In general, consult your Sony dealer about necessary
periodic maintenance checks.
Digital hours meter display modes
The digital hours meter has the following four display
modes.
• T1 (OPERATION) mode
The cumulative total hours during which the unit is
powered on is displayed in 10-hour increments.
• T2 (DRUM ROTATION) mode
The cumulative total hours of drum rotation with tape
threaded is displayed in 10-hour increments.
• T3 (TAPE RUNNING) mode
The cumulative total hours of tape transport operation
for fast forward, rewind, playback, and search (except in
still search mode) is displayed in 10-hour increments.
• CT (THREADING) mode
The cumulative number of tape threading/unthreading
operation pairs is displayed in 10-operation pair
increments.
For all modes except T1 (OPERATION), there are two
types of count: a “trip” count, which is resettable, and the
cumulative total from manufacture, which is unresettable.
