How do I know when the CS540 battery is low?

If you are on a call and the headset battery is critically low, you will hear a repeated single beep every second indicating the battery is low. You should recharge the Plantronics CS540 wireless headset immediately.

If you are not on a call and press the call button, you will hear three low tones if the battery is critically low. You should recharge the headset immediately.

Plantronics CS540 has a user-replaceable battery. To ensure replacement batteries meet Plantronics high-quality standards and for optimal performance, use only OEM replacement batteries by Plantronics.

With a single full charge, the CS540 will provide up to 6 hours of talk time. Talk time will be reduced when operating in wideband mode or if the headset is used consistently a far distance from the base.
