2 Wideband/Narrowband Audio Switch

The CS545-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.
