Logic Off switch and indicator

If pressed while the magnetic tape drive is powered on,
logical power (the DC power to the circuit boards) is
removed. The indicator light comes on to signal a standby
power condition.

Logic On switch and indicator

If pressed while the circuit breaker is on and the magnetic
tape drive is in a standby power condition, the logical power
(the DC power to the circuit boards) is returned to the
magnetic tape drive.

File protect indicator

The file protect indicator is lit when the write-enable ring in
the magnetic tape reel is absent. When this indicator is on,
data cannot be written to or erased from the tape.

BOT indicator

The BOT indicator is lit when the tape is positioned at the
BOT marker (a reflective band on the tape indicating the
beginning of data).

Load/Rewind switch

If the magnetic tape drive is powered on and a tape
threaded, press the Load/Rewind switch to initiate tape
loading. If the tape has already been loaded and threaded,
press the Reset switch and then the Load/Rewind switch to
rewind the tape to the BOT marker.

Note: Following the load or rewind operation, the unit
automatically sets to 25 inches per second (ips) start/stop
mode and positions the tape accordingly. The rewind rate is
75 ips.
