Physical obstructions and electromagnetic interference may shorten this range. Headset sound quality may slowly deteriorate the further the headset is away 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 (three quick descending notes) 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 back in 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. 8.3 WIDEBAND AUDIO The Jabra PRO 9450 supports both wideband and narrowband audio. Wideband audio offers better sound quality at a reduced battery time. Narrowband is default-enabled for desk phones. Wideband is default-enabled for softphones. Change wideband audio settings 1.
