Make and answer an intercom call
Use the intercom feature for conversations between handsets. This feature is 
only available if you have two system handsets.
Press INT on your handset when not in use.
If you have 2 handsets, your originating handset 
screen shows Calling HS X. The other handset rings 
and its screen shows HS X is calling.
If you have more than 2 handsets, your originating 
handset screen shows Intercom to. Use the dialing 
key to select the destination handset. The originating 
handset screen shows Calling HS X (X represents the 
handset number). The destination handset rings and 
its screen shows HS X is calling.
To answer the intercom call, press any dialing key  
(0-9,   or #),  PHONE/FLASH,  /SPEAKER or INT  
on the other handset. Both handset screens now  
show Intercom.
To end an intercom call, press  OFF/CANCEL or place 
the handset back in the telephone base or charger. Both 
handset screens now show Intercom ended.
notes:
Before the intercom call is answered, you can cancel it by pressing  OFF/CANCEL or INT 
on your originating handset.
If the called party does not answer within 100 seconds or if the handset is in use, on a call or 
out of range,
 your originating handset shows Unable to call.
If you have four handsets, of which two handsets are on an intercom call, the other two 
handsets can be used on an outside call (see Join a call in progress on page 25) or a separate 
intercom call.
Answer an incoming call during an intercom call
If you receive an incoming outside call during an intercom call, there is an 
alert tone.
To answer the incoming outside call:
Press  PHONE/FLASH. The intercom call ends automatically.
To end the intercom call without answering the incoming outside call:
Press  OFF/CANCEL. The intercom call ends and the handsets ring for 
the incoming call.
