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
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.

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!” on the time counter
display. At the same time the unit ejects the cassette
automatically. If this happens, leave the unit’s power
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 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.
