Instruction manual

Features
A Headset Hang Up button must be programmed for an MLX telephone or MLX
DLC through centralized telephone programming for the user or operator to be
able to use the headset.
A Headset Hang Up button is not needed and cannot be programmed on a
Queued Call Console (QCC).
To give control of headset/handset operation to an MLX telephone user or MLX
DLC operator who has a Headset Hang Up button, a Headset Status button
can also be programmed, as described in the next section. On a telephone or
console with a Headset Hang Up button, but without a Headset Status button,
headset operation is always on.
NOTE:
If an MLX telephone or MLX DLC has a Headset Status button and/or a
Headset Auto Answer button (described in the following two sections) in
addition to a Headset Hang Up button, the Headset Hang Up button can
be removed through centralized programming without removing the
Headset Status or Headset Auto Answer button. If either of these
features is on, the green LED next to the button stays on. However, the
telephone or console is no longer in headset operation and neither the
Headset Status nor the Headset Auto Answer button has any effect,
whether on or off, until a Headset Hang Up button is reprogrammed for the
extension.
Headset Status
When a Headset Hang Up button is programmed on an MLX telephone or MLX
DLC, Headset Status is automatically turned on. Programming a Headset
Status button in addition allows the user or operator to turn headset operation
off and on manually. With headset operation on (green LED next to Headset
Status button is on), the user or operator answers and makes calls with the
headset. With headset operation off (green LED next to Headset Status button
is off), the user or operator answers and makes calls with the handset.
Two things are necessary for an MLX telephone user or MLX DLC operator to
use the Headset Status feature:
■ A Headset Hang Up button must be programmed, as described in the
previous section.
■ A Headset Status button must be programmed on the telephone or
console, either through extension programming or through centralized
telephone programming.
A Headset Status button is a fixed feature on a QCC and cannot be deleted or
changed.
To use Headset Auto Answer, Headset/Handset Mute, or Headset Hang Up on
a telephone or console with a Headset Status button, Headset Status must be
on.
