Control	Description
Density Select Button	Refer to subsection 2.4.2.
Unload Button	Use the Unload button to unload the tape cartridge. When you
	push the Unload button, the tape drive waits until any active
	writing of data to tape is completed, then begins its unload
	sequence.
	The drive rewinds the tape medium back into the cartridge and
	writes the current or updated tape directory to the tape. The tape
	must be completely rewound and unloaded into the cartridge
	before the cartridge can be removed from the tape drive. A
	complete unload operation may take 17 seconds from Beginning
	of Tape (BOT).
	Note that if the tape drive is in an error state (all LEDs on the right-
	or left-hand side of the front panel are flashing), pushing the
	Unload button causes the tape drive to reset and unload the tape, if
	possible. The Operate Handle LED will be lit steady if this is
	possible.
Cartridge Insert/Release	Use the Cartridge Insert/Release Handle to load or eject a tape
Handle	cartridge only when the tape drive’s Operate Handle LED is lit and
	after the beeper sounds its tone. Lift the handle to its fully open
	position, or lower it to its fully closed position.
Operate Handle Beeper	A beeper sound indicates that the cartridge insert/release handle
	can be safely operated. When the drive emits its single beep tone,
	verify that the green Operate Handle LED is lit steadily before
	opening the handle.
	CAUTION: To prevent damage to the tape drive, never operate the
	insert/release handle unless the green Operate Handle LED is lit and
	you have heard the beep tone that signals that the tape drive’s
	handle can be opened.
