Maintenance

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.
