Plantronics Discovery 975 supports multipoint
technology, which allows you to use one earpiece
with two different Bluetooth mobile phones.

multipoint feature on. When this feature is off, your
earpiece can connect to only one Bluetooth phone.

hold the volume and call control buttons
simultaneously until earpiece turns on
and indicator flashes white 2 times.
2 To pair earpiece to a second phone, see
“Pairing Your Earpiece” on page 7.
NOTE To turn the multipoint feature off, repeat
step 1. The indicator flashes white 1 time to
indicate multipoint is off.
How to Initiate a Call
The earpiece initiates or redials a call on the phone
that most recently made an outgoing call. To use the
second phone, initiate the call using the controls on
the second phone.
How to Answer a Call While Talking on the
Other Phone
To answer the second call, the first call must be
terminated or placed on hold using the phone, if
your phone has a hold feature.

the existing call.
