BLUETOOTH PAIRING
Before using your Headset for the first time, you
must pair it with another Bluetooth device such
as a mobile phone. Make sure the Headset is
fully charged.
• Look in your Bluetooth device manual for

Bluetooth wireless connection.

phone until the phone display shows “Look
for Devices”, or equivalent, as a selection.
1. With your Headset turned off, hold down
the Call Control Button until the Headset
Status Indicator briefly glows blue, then
flashes red and blue. The Headset is now
in discovery mode and will stay that way
for 30 seconds.
2. On your phone, highlight and select “Look
for Devices”, or equivalent, to activate the
scan for the Headset.
3. When the phone display shows the scan
results, select “640 Plantronics”. The
phone will continue to search for the
Headset.

passkey, type “0000” and press Enter.

USING MULTIPOINT
(MORE THAN ONE
BLUETOOTH DEVICE)
TO USE THE SECOND DEVICE Initiate
the call using the controls on the second
device. The second device will form the
link with the headset.
ANSWER A CALL An incoming call on
either device will ring through the headset.
In most cases, the ring tone from the
device will transfer through to the headset,
allowing the user to determine which
device is ringing. In some cases, however,
the headset will apply a ring tone to the
incoming call. In either case, the user
may be able to determine which device is
ringing by the distinct ring tone.
To answer the call, press the Call
Control Button.
TO ANSWER A CALL ON ONE DEVICE
WHILE TALKING ON THE OTHER There is
no capability for placing one call on hold
while answering another. Therefore, to
answer the second call, the first call must
be terminated.
Terminate the first call by pressing the call
control button once.
Wait for the beep and then answer the
second call by pressing the Call Control
Button again. If you choose not to answer
the second call, and you have voice mail
on the second device, the call will go to
voice mail.
Plantronics Discovery 640 supports Multipoint
technology, which permits simultaneous
connections with two different Bluetooth audio
devices. To pair another Bluetooth device:
repeat the previous pairing steps with the
new device.
TO PAIR ANOTHER BLUETOOTH DEVICE
Repeat the previous pairing steps with the
new device.
INITIATE A CALL The headset will assume
you wish to initiate a call on the device
recently used.
