186 Operating Information
When a new tape carttidge is inserted, the TZ30
perf
onns its calibration routine
as it executes the first command. This calibration may take up to 30 seconds
of winding and rewinding the tape.
While the tape is in use, the yellow LED blinks irregularly.
If you use a tape cartridge written on a
TK70 tape drive, the orange LED
lights to indicate that the tape is write-protected. The orange LED also lights
if the write-protect switch on
a CompacTape or CompacTape II cartridge is in
the write-protect position.
NOTE
The orange LED turns off if you set the write-protect switch to the write-
enable position while the cartridge is in the drive. However, VMS still
gives a message that the tape is write-protected. Dismount the tape and
mount it again
by
giving the
DISMOUNT
and
MOUNT
commands.
