Condensation
Troubleshooting and Maintenance 8 Chapter
If you move the unit suddenly from a cold to 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 display section of the lower control panel. 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 messages appear immediately after powering on:
Leave the unit powered on and wait until the alarm messages disappear. You cannot load a cassette into the unit while the alarm messages are being displayed Once the alarm messages disappear, the unit is ready for use.
