Handset Modes
Standby(on-hook)
In the standby mode the handset is waiting for an incoming call or for
the user to place an outgoing call. The extension number is shown on
the display and there is no dial tone. In this mode, the handset is
conserving battery power and bandwidth.
Active (off-hook)
To place a call, press the Start Call key. This transitions the handset to
active off-hook mode. There is a dial tone, the handset is in
communication with the PBX and the display shows information as it
is received from the PBX. The handset is also in the active mode when
you receive a call.
The active modes utilize the most bandwidth and battery power. To
conserve these resources, return the handset to the standby mode
when a call is completed by pressing the
End Call key.
Active (on-hook)
To access the on-hook features of the handset, it must be in the active
on-hook mode. To transition from the active off-hook mode to the
active on-hook mode, press the
Start Call key. In this mode, the user
may access the on-hook OptiGuide features. Return to the standby
mode by pressing the
End Call key when finished accessing the on-
hook features.
