2 Wideband/Narrowband Audio Switch

The CS540-XD has wideband audio, which allows speech to sound clearer and more natural. If
your desk phone is capable of wideband audio, set the Wideband-Narrowband audio switch to
yellow for wideband.
NOTE: Talk time will be reduced when operating in wideband mode.
Set the switch to black (narrowband) for longer headset battery life or to increase the number
of systems that can work in a small area.
