Dock the headset. When docked correctly the headset battery will begin charging, if needed. Charge for 20 minutes or until the battery indicator on the base is steady green.

CONFIGURING THE DESK PHONE AUDIO

Due to the large range of desk phone brands/models available, a clear dial tone must be set before first-time use of the Jabra PRO 920 Duo. Setting the clear dial tone will enable the Jabra PRO 920 Duo to function correctly with your specific desk phone. Additionally it is also important to set the microphone volume for optimal sound quality.

SET A CLEAR DIAL TONE

1. Put on the headset.
2. Press the headset button on the desk phone, or lift the desk phone handset.
3. Locate the clear dial tone switch on the back of the Jabra PRO 920 Duo base, as illustrated, and while listening in the headset for a clear dial tone, rotate the switch from A to G.
4. Determine the best switch position. The dial tone should be strong, clear and undistorted.
5. When the clear dial tone is set, press the headset button on the desk phone, or return the desk phone handset to the receiver.

SET THE MICROPHONE VOLUME

1. Put on the headset.
2. Get a dial tone by pressing the headset button on the desk phone, or by lifting the desk phone handset.
3. Make a test call. Call a friend or colleague to test your speaking volume. Ensure the listener does not adjust their own volume.
4. Adjust the microphone volume using the microphone + / - volume buttons, as illustrated, if your speaking volume is too loud or too quiet for the listener.
5. When the microphone volume is set, end the call.

Note: To reset the microphone volume to the factory default setting, make a call and then press and hold both microphone + / - volume buttons until a tone is played, and then release the volume buttons.

Ending, or leaving, the conference

The primary headset user can end the conference by hanging up on the call. The call is ended for all headsets. Guests can leave the conference by tapping the multi-function on their headset, or by docking the headset with the base. The conference call is still active for the other headset(s).

ADVANCED JABRA PRO 920 DUO FEATURES

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.

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.

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.

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.

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.

SUPPORT

FAQS AND TROUBLESHOOTING

Q How do I pair my headset with the Jabra PRO 920 Duo 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.

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 base 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?

A Ensure 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.

A Jabra PRO 920 Duo supports a maximum range of up to 120 m (base to headset). Range varies according to the environment in which the headset is used.

A Yes, the Jabra PRO 920 Duo is able to pair with four headsets in total: one primary and three secondary headsets.

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 Duo headset?
