Wideband/Narrowband Switch; Auto Answer Switch - Plantronics CS540 User Manual

2 Wideband/Narrowband Switch

The CS540 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 switch to green for
wideband.
Set the switch to red (narrowband) for longer headset battery life or to increase the number of
systems that can work in a small area.

3 Auto Answer Switch

Auto answer saves a button press to establish the radio link between headset and base. When
auto answer is set to red you must press the headset call button to answer an incoming call.
When Auto Answer is set to green you can answer a call just by lifting headset from the base.
NOTE Auto answer/end capability requires the use of an EHS cable or HL10 lifter. Visit
plantronics.com/accessories for more information.
