which are located under the numeric dialpad, beneath the
volume rocker button.
Each set can have up to eight Intercom buttons. On the M7310,
M7324 telephones, these buttons assign to the position above
the Handsfree/Mute button at the bottom right-hand position
on your telephone. On the T7316 set, these buttons assign to
the buttons on the bottom right set of buttons, starting from the
bottom button.
On the M7208 and T7208 sets, these buttons assign above the
bottom button.
Each telephone can have up to four answer buttons. On the
M7310 set, they appear above Intercom buttons in the right
column and continue up from the bottom in the left column,
replacing the features on those buttons. On the M7208 and
T7208 sets, answer buttons appear above the Intercom buttons
and below external line buttons in a single column.
External line buttons appear in ascending line order, starting at
the top button in the left column of the M7310 Norstar set
They also start from the top button on the M7208 and T7208
sets. If more than five external lines are assigned to an M7310
telephone, or more than 12 to an M7324 telephone, assignment
continues down the buttons on the right column, erasing the
features on those buttons. Line buttons have priority over
feature access buttons but not Handsfree/Mute, Intercom, or
answer buttons.
