Muting a Headset During A Call
To mute/unmute the call, press the volume/mute button in. The
USB adaptor light will flash red when the headset is muted.
When mute is activated, you will hear three high tones. When
unmuted, you will hear three low tones.
After the Plantronics software is loaded, the mute tones can be
turned off by going to Start > Programs > Plantronics Control
Panel > Devices > Device Settings > Headset – Mute Tone.
For your safety, do not use headset at high volumes for
extended periods of time. Doing so can cause hearing
loss. Always listen at moderate levels. For more information
on headsets and hearing visit:
plantronics.com/healthandsafety.
Powering Up the Headset
Assure a charged battery is attached to the headset and the
battery on/off switch is set to the “on” position.
Talk Time
With a single full charge, the Savi W445 will provide up to 7
hours of talk time in narrowband mode. Talk time will be reduced
when operating in wideband mode and/or if the headset is used
consistently at a far distance from the adapter. The battery can be
replaced, even mid-call, giving essentially unlimited talk time. See
“Replacing Your Headset Battery.”
Conserve Talk Time:
1Turn the battery power switch to Off when not in use.
2 Switch audio to narrowband (see PC Audio Bandwidth on
pg. 14, 15 for instructions)

Replacing Your Headset Battery
1 Once your spare battery is fully charged, remove the
spare battery from the battery compartment on the
side of the Deluxe Charging Cradle or from the back of
the Deluxe USB Charging Cable. Because the battery is
hot-swappable, you won’t lose an active call if you replace the
battery within five minutes.
2 Disconnect the battery from the headset.
3 Slide the charged battery onto the headset until you
hear a click.
4Charge the spent battery by placing it in the Deluxe Charge
Cradle battery compartment and closing the door, or on the
Deluxe USB Charging cable as shown.

green, the headset and the USB adapter are subscribed
to one another.
To ensure subscription was successful, press the call control
button: the headset will flash white and the USB adapter will
flash green.
NOTE If the subscription process times out after two minutes or if
the subscription process fails, the USB adapter indicator light will
become solid red for four seconds and then return to its previous
state. If this occurs, try to re-subscribe the headset again.
Ending Subscription
If the USB adapter is in subscription mode and you want to stop
the adapter from searching for a headset, press the subscription
button again. The subscription light will turn solid red for four
seconds and then go to its previous state.

Plantronics Savi User Guide 14
Conferencing Up to Three Guest Headsets
While on a call, you can subscribe up to three guest headsets to
your USB adapter for conferencing. As you add headsets to the
adapter, you can see the number of Conferenced headsets in the
Plantronics Hub “About” tab under “Connections.”
Guests may conference in as described below:
1 While you are on a call, place the guest’s headset into
subscription mode.
2 Short press (less than one second) the subscription button on
the USB adapter. The USB adapter light will flash yellow and
green.
3 The USB adapter light will then turn solid yellow and you will
hear a tone in the master headset indicating a guest wishes to
join the call.
4 If you press the call control button on the master headset
within five seconds, the guest is joined to the call.
If you do not press the call control button within five seconds,
the request to join the call is rejected and the guest will hear an
error tone in their headset.
5 Guests may leave the conference call by pressing their call
control button.
When they do you will hear a single tone in the master headset
as each guest leaves the call.
Conferencing Additional Headsets and
Security Levels
Your Savi 400 Series headset system (v28 or later) supports
DECT Forum recommendations for Enhanced Security. Products
with Enhanced Security are marked with the DECT Forum security
logo on the base.
Both your headset and USB adapter are compatible with older
(prior to v28) headset bases and headsets supporting older
versions of DECT. Below is helpful information if you plan to use
Enhanced Security and older DECT components together.
If your Enhanced Security headset or USB adapter is conferenced
with an older headset or headset base the resulting security level
for the mixed headset and base combination will be set to the
level of the older version of DECT for all calls. This is because
older system components are not able to support Enhanced
Security.
All subscription details above apply when conferencing an
Enhanced Security headset to an older USB adapter, or visa
versa, however there are unique system alerts indicating that the
system is changing the security level from Enhanced Security to
the older version of security.
If an older headset is subscribed to an Enhanced Security
USB adapter:
• The subscription LED (on USB adapter) will flash GREEN 3
times followed by YELLOW 2 times. This flash pattern repeats
2 times.
If an Enhanced Security headset is subscribed to an older USB
adapter:
• The Enhanced Security headset will play a security notification
tone.
• The mono-colored LED on the headset will flash 3 times, then 2
times. This flash pattern is repeated 2 times.

Auto Answer
When enabled, this feature will configure your headset to automatically answer a call when it
is removed from the charge cradle.
Audio Sensing
Audio Sensing is a special feature supported by Plantronics wireless devices that can detect
an audio signal at the USB port and automatically establish the radio link between the base
and the wireless headset without the user having to press the call control button. When the
Configure Lync Dial Tone parameter is set to On, every time the user presses the call control
button, the Lync dial tone will be heard (assuming the user wants to make a softphone call).
However, the user may have pressed the call control button to listen to PC music, etc., and
does not want to hear the dial tone. In this case, if the user sets the Audio Sensing parameter
to On, the radio link will be established automatically when any PC audio is detected at the
USB port, thus eliminating the need for the user to press the call control button.
