Secrecy
• To obtain secrecy on an external
call, press the
INT button. Display
shows your handset’s internal
number and you hear the internal
dial tone. This allows you to talk
to someone in the same room,
without your caller hearing the
conversation. Instead your caller
hears a melodious tone.

your telephone call with the
external party.
INT RCL

during your call and also for a few
seconds after your call is completed.
Operating with
additional handsets
‘Ring priority’ and ‘collective
ringing’
Your Diverse 2015 will ring all
handsets whenever there is an
incoming call. This is called
collective ringing. Ring priority
means an incoming call will ring
first at a preferred handset. If there
is no answer, the call will ring all
other handsets.
The default setting for your Diverse
2015 is for collective ringing.
Secrecy is not available for internal
calls.
