Telephone operation

Use the ringer switch on the right side of the base 
to adjust the ringer volume to 

OFF, LO or HI. If 

the ringer switch is set to 

OFF, this telephone will 

not ring when there is an incoming call. However, 
the 

CALL INFO indicator will still flash to indicate 

an incoming call.

The

 CALL INFO indicator on the telephone is used 

to indicate there is additional information in the 
display about the current or previous calls.
