Talk Time

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 at a far distance from the base.

Low Battery Warning

If you are on a call and the headset battery is critically low, you will hear a repeated single low tone every 15 seconds indicating the battery is low. You should recharge the 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.
