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
headset (see Section 7.5).
PeakStop™ acoustic shock protection
PeakStop™ automatically suppresses sounds over 118dB(A), protecting hearing from acoustic shock.
ENGLISH
7. ADVANCED JABRA PRO 920 FEATURES
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 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 provides several built-in power management features for conserving energy.
Auto sleep mode
Auto sleep mode can be enabled using the Jabra PRO 920 base (see Section 7.5). Auto sleep mode is off by
default. When enabled, the Jabra PRO 920 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 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 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.

8.1 FAQS AND TROUBLESHOOTING
Q How do I pair my headset with the Jabra PRO 920 base?
A Dock the headset with the base to initiate pairing. Pairing will occur automatically, unless the base is currently
linked with a primary headset (a headset already paired with the base). Alternatively you can force pair a new
primary headset, if there is currently a primary headset already paired with the base.
ENGLISH
8. SUPPORT
Q Can I pair my headset directly with a third-party DECT phone, or base?
A No. The headset can only be paired with a Jabra PRO 920 base.
Q Why doesn’t my headset work with my desk phone?
A Check the following:
• Ensure the headset battery is charged. The keypad battery icon will be blinking green when charging,
or solid green when charged.
• Ensure the headset is in range of the base. The range is up to 120 m, depending on environment.
• Ensure the headset and base are paired. To initiate pairing, dock the headset.
Q Why does nothing happen when I try to use my desk phone?
AEnsure the base is powered on, and check there is a dial tone. Lift the desk phone handset, or press the
headset button on the desk phone, to get a dial tone. If there is no dial tone, double-check all cables have
been correctly connected.
Q The person I am calling cannot hear me. Why?
A The clear dial tone or microphone volume settings might be incorrectly set. Read Section 3 and 4 of this
manual.
Q Why am I getting a buzzing sound in my headset?
A Assuming the device has been set up correctly, the desk phone may not be fully immune to the radio signals
the headset uses. To overcome this problem, move the headset base at least 30 cm away from the desk
phone.
Q When I try to make a call on my desk phone, the GN1000 RHL lifts, but the call is not connected.
A Ensure the base is connected to the desk phone handset port, and not the desk phone headset port. The
GN1000 should not be connected to the headset port.
Q Is it possible to automate calling and answering on my desk phone without using a handset lifter?
A Yes, if the desk phone has an electronic hookswitch feature. Check your supplier for compatibility with your
phone, and/or consult the support section on www.jabra.com.
Q Why does my desk phone’s electronic hookswitch not work with my headset?
A Please check your specific desk phone documentation for electronic hookswitch compatibility and
configuration settings. Alternatively visit www.jabra.com.
Q What is the range on the Jabra PRO 920?
A Jabra PRO 920 supports a maximum range of up to 120 m (base to headset). Range varies according to the
environment in which the headset is used.
Q Can I make a conference call using multiple headsets?
A Yes, the Jabra PRO 920 is able to pair with four headsets in total: one primary and three secondary headsets .
Please see section 6.3 of this manual for more information.
Q Can I turn the headset off to save power when I’m away from the base?
A Yes. Press and hold the headset multi-function button on the headset for five seconds to power the headset
off. To power the headset back on, dock the headset with the base, or tap the multi-function button.
Q What is the talk time for a Jabra PRO 920 headset?
A Up to 8 hours talk time.
Q My headband/earhook/neckband is broken. How do I purchase another one?
A Contact your local Jabra supplier.
