Introduction
Volume control
Under the dial pad is a volume control which enables you to adjust the volume of peoples' voices.
Keys with indicators
The next section provides an explanation of the keys with indicators you find on your console. Remember,
your Meridian 1 system may not have all of the features described in this guide, and therefore may not
have all of the operating keys and indicators listed here. Indicators come on, flash at different speeds, and
go off at various points during a procedure to indicate something important. The meaning of the activity
of an indicator depends on the situation.
Vertical keystrip 1: Trunk Group Busy keys
At the far left, you will find a row of ten Trunk Group Busy keys and indicators.
The Trunk Group Busy keys enable you to deny users access to trunk groups from 0 to 9 (0 to 7 on the
M1250) and have calls to those trunk groups sent to your console instead. The trunk group indicators
show the status of each group of trunks:
steadily lit — You have busied out all trunks in the group by putting the console into shift mode, and then
pressing the Trunk Group Busy key. With the console in SHIFT mode, press the Trunk Group Busy key
again to turn the indicator off and permit access to the trunk group.
flashing — All trunks in the group are busy.

Note: Your console may be set up so that the two leftmost rows of keys with indicators act as
incoming call indicator (ICI) keys in regular mode, and as Trunk Group Busy keys in shift mode. In
this case, the right-pointing half-diamond indicators correspond to the ICIs, while the left-pointing
half-diamond indicators correspond to the trunk groups.
