7. ADVANCED JABRA PRO 920 DUO FEATURES
7.1 SAFETONE™ AUDIO PROTECTION
SafeTone™ provides effective hearing protection against potential risks, such as acoustic shock and noise exposure.
SafeTone™ consists of two components, PeakStop™ and IntelliTone™ and can be set using the Jabra PRO 920 Duo
headset (see Section 7.5).
PeakStop™ acoustic shock protection
PeakStop™ automatically suppresses sounds over 118dB(A), protecting hearing from acoustic shock.
IntelliTone™ noise exposure protection
IntelliTone™ offers protection against acoustic shock and noise exposure over 85dB(A), corresponding to up to 8
hours of daily talk.
7.2 WIRELESS RANGE
The Jabra PRO 920 Duo supports a maximum wireless range of up to 120 meters. Physical obstructions and
electromagnetic interference may shorten this range. The wireless range can be adjusted to prevent interference
with other wireless devices (see Section 7.5).
Headset sound quality may deteriorate the further the headset is from the base, and may improve the closer the
headset is to the base. When the headset is completely out of range, a unique tone will be played in the headset
every few seconds.
If the headset is on a call when moved out of range, the audio will be lost; however the call will remain active at
the base for 120 seconds. To restore audio to the call, move the headset into range of the base.
If the headset remains out of range of the base for more than an hour, the headset will power down to conserve
battery.
7.3 POWER MANAGEMENT
The Jabra PRO 920 Duo provides several built-in power management features for conserving energy.
Auto sleep mode
Auto sleep mode can be enabled using the Jabra PRO 920 Duo base (see Section 7.5). Auto sleep mode is off by
default. When enabled, the Jabra PRO 920 Duo will automatically enter sleep mode after 8 hours of inactivity,
as indicated by the battery indicator slow flashing blue. Sleep mode will end when docking or undocking the
headset.
Automatic headset power off
After 60 minutes of no link between headset and base, the headset will automatically power off. To power the
headset on, tap the multi-function button.
7.4 REMOTE CALL CONTROL
Remote call control (or hookswitch) is the control mechanism used to answer or end a call on a desk phone. To
enable the Jabra PRO 920 Duo headset to answer or end calls, the desk phone will need to have a Jabra Link or a
GN1000 installed.
Electronic Hookswitch (EHS)
An electronic hookswitch is a feature on some desk phones that enables calls to be answered or ended by the
headset multi-function button. To use this feature an electronic hookswitch adapter (e.g. Jabra Link) needs to
be connected between the desk phone and the Jabra PRO 920 Duo base. To purchase a Jabra Link contact your
supplier, or visit www.jabra.com.
GN1000
A GN1000 manually lifts the handset from the desk phone receiver to automatically place or answer a call. To
purchase the Jabra GN1000 remote handset lifter contact your supplier, or visit www.jabra.com.
