ENGLISH 7. ADVANCED JABRA PRO 920 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 base (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. 7.2 WIRELESS RANGE The Jabra PRO 920 supports a maximum wireless range of up to 60 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 changing to solid blue. Sleep mode will end when any of the following events occurs: • An incoming call. • An outgoing call. • Docking or undocking the headset. Automatic headset power off After 60 minutes of no audio link between headset and base, the headset will automatically power off. To power the headset on, press and hold the multi-function button for 5 seconds. 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 an electronic hookswitch (EHS) or a remote handset lifter (RHL) 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 needs to be connected between the desk phone and the Jabra PRO 920 base. To purchase an electronic hookswitch adapter contact your supplier, or visit www.jabra.com. Remote handset lifter (RHL) A remote handset lifter manually lifts the handset from the desk phone receiver to automatically place or answer a call.
