36 / Setting Handset Features
Priority call: If a Priority call is made to your T7406 telephone that
does not have DND active, and the call is answered but the originating
caller then releases the call, you must still press an intercom line and
the ≥ button before the line is actually released. If you choose not to
do this, the handset stops providing ring notification of incoming calls,
refer to Ring Notification.
Voice Call Deny (F88): This feature has been purposely set as the
default for the handset, since voice calls cannot be made to the T7406
handset. If this setting inadvertently gets turned off by the system
administrator or the user, someone attempting to make a voice call to
the handset may not receive the No Voice Call display on their
telephone. As well, the call will continue as a normal call to the T7406
set.
LCD Contrast Level: This feature is not adjustable, either through the
handset or through system programming. Contrast has been
automatically set to an optimum level.
T7406 and M7410 interaction: If there are any M7410 telephones
installed on the system, you can attach only one base station and three
handsets in the same area. In this case, the base station must be set to
the upper band. Refer to Installing the Base Station on page 21 for
instructions about setting the base station to the lower band.
