Fixed keys

The following fixed keys are provided:

Primary directory number

This fixed key is Key 1 on all Meridian modular telephones. M2006 sets
only have one line, therefore, Key 1 on M2006 sets is simply called a
directory number. The PDN (or DN) key is always positioned as the bottom
right key (Key 1).
The DN key provides the only line for incoming and outgoing calls on the
M2006 set. The primary directory number (PDN) provides the main line for
incoming and outgoing calls for the M2008, M2008HF, M2616, M2216, and
M2616CT sets. The PDN is the default directory number for various
features. Use the PDN key for on-hook dialing and for taking PDN calls off
hold.

One key with two toggle positions controls volume (<<< >>>). It is located
at the bottom of the set's numerical keypad. Pressing the right side of the
toggle key (

new volume adjustments are made. If the telephone set is equipped with a
display module, then the volume can be adjusted at any time with the setting
displayed on the screen (in Program Mode).
