Below the keypad, and towards the bottom edge of the
telephone are four, circular-shaped buttons, each with a
semi-circular recess on one side of the button. They are
from left to right as follows: The left button has a recess on
the right side and has the word Boost below it. This is the
"Boost" button to amplify the volume. The next button has
a recess on the bottom edge and has the word Recall
below it. This is the "Recall" button which is used for
accessing network services, such as double calls, three-
party conference calls and call transfer. The next button
has a recess on the left side and has the word Redial
below it. This is the "Redial" button, and when pressed,
this calls the last number dialled (stored in the memory).
The button on the right of this row has a red LED situated
at the top edge of the button and has the word Headset
below it. This is the "Headset" button, which should be
pressed to activate the telephone when making a call
using a headset. The headset should be plugged into the
top edge of the telephone.
The last few buttons on the front of the telephone are
situated on the right towards the edge. Towards the top of
the telephone are three circular-shaped buttons, one
above the other. Above these buttons are the letters Mem,
and these are the three quick-dial memory buttons. The
top button (memory one - M1) has one tactile dot on it, the
middle button (memory two - M2) has two tactile dots on it,
and the bottom of the three buttons (memory three - M3)
has three tactile dots on it. Once a telephone number is
programmed to one of these three buttons it can be dialled
instantly by just pressing the button.
