Signaling & Notify  
Receiving Messages  
When your red Message light is on, you  
have a message from a co-worker.  
To program:  
See Programming Buttons & Settings, p. 31.  
Messages are identified by the name or  
extension of the caller, along with the time  
and date the person called. Depending on  
how your system is set up, you may also  
have a voice mail message or a fax. A  
message may be identified on your  
telephone's display in these ways:  
Signaling. Program a button that will cause  
a co-worker’s multiline telephone to beep.  
The other person can then call you in  
response to the beep. You must program a  
different line button for each extension you  
wish to contact. To beep the recipient’s  
telephone, just press the button, and the  
other telephone beeps for as long as you  
hold down the button. A programmed  
Signaling button also acts as an Auto Dial  
button (see p. 20). To dial the extension, lift  
the handset or press the Speaker button;  
then press the Signaling button.  
ATT You have a message from another  
system operator.  
FAX You have a fax.  
VMS You have a voice mail message.  
EXT Indicates the extension number of the  
person who called.  
Notify. This feature simply lights a line  
button on the recipient’s telephone,  
providing a silent message light that alerts  
the other party to call you. To use this  
feature, you must program a Notify Send  
button (labeled, for example, Notify Mary)  
on your telephone and the recipient must  
program a Notify Receive button (labeled,  
for example, Call Jim) on his or her  
telephone. Communication is one-way only,  
and buttons must be programmed for each  
extension you notify.

Often-Used Features  
Coverage  
Call Waiting  
If Call Waiting is on, you hear a call-waiting  
tone when a call comes in and all your lines  
are in use. This feature works only on SA  
and ICOM buttons, not on line buttons  
labeled with telephone numbers.  
To program:  
See Programming Buttons & Settings, p. 31.  
Coverage allows calls to your extension to  
ring elsewhere, so that they can be handled  
by someone else. If your system has voice  
mail, your calls can also be covered that way.  
There are three types of coverage:  
When a call is waiting, you hear a single  
beep (inside call) or two beeps (outside call).  
To complete a call and answer a waiting  
call:  
1. When you hear the call-waiting tone, hang  
up.  
2. When the telephone rings, lift the handset  
or press the Speaker button.  
Primary Coverage. If your calls are  
covered this way, they ring immediately  
at the covering telephone.  
Secondary Coverage. The covering  
telephone rings after a delay of 2 rings,  
giving you a chance to answer first.  
Group Coverage. Calls for a group of  
people (coverage group) may be  
covered by one or more people. Your  
System Manager can tell you how this  
works at your office.  
Covering telephones are programmed with  
Cover buttons used to answer calls for  
others. Delay Ring on the covering telephone  
can add a longer delay before your calls ring  
there. If line buttons on your telephone are  
set to No Ring, however, calls on those lines  
are not covered (see Rings, p. 4).

call directly or transfer a call directly to  
another user’s voice mail. You can also use  
the feature after you have dialed the  
extension; just do Step 1 below.  
Extension Status lets you monitor telephone  
status in your system. You can change status  
either at your console or at the extension by  
using either a programmed line button or a  
feature code. You can monitor status only from  
a console. Extension Status must be  
programmed systemwide and assigned to the  
console. Consult your System Manager to find  
out how your company uses each status  
feature and line button on the console.

mail or transfer a call directly to another  
user’s voice mail:  
1. Do one of the following:  
Press the programmed Direct Voice  
Mail button.  
Press the Feature button and select  
DirectVM[DrcVM]or dial 56.  
2. Press an Auto Dial or DSS button, select a  
Directory listing, or dial the number of the  
extension whose voice mail you want to  
call or transfer a call to.

The room is occupied, and telephone is in  
regular call-handling status.  
ES1. The light next to that extension is  
flashing. The room is unoccupied and ready  
for cleaning; outside calls cannot be made  
from the telephone.  
Note: If you are transferring a call to an

Do Not Disturb  
Must be programmed on a button.

This feature prevents calls from ringing at  
your extension, although outside calls cause  
the green lights at line buttons to flash. If you  
have coverage, your calls are covered.  
Inside callers with display telephones see

call you. A system operator or the person  
providing individual coverage for you can still  
call you. Callback calls and returning  
transfers ring at your telephone.  
To use:

feature on or off. When the feature is on, the
