How does an online indicator work?
Have you ever found yourself engrossed in a crucial sales deal at your desk, only to be interrupted by someone who didn’t realize you were on the phone? While a stern glare often effectively conveys your displeasure, wouldn’t you prefer a more “user-friendly” approach to communicate your feelings?
Consider using a stylish phone line indicator designed specifically for the Savi wireless headsets. This square-shaped indicator features the universal symbol for a headset and has a pulsing blue light that resembles a heartbeat, indicating the presence of a live person on the headset. The indicator has a 5-foot cord length. However, it’s important to note that it comes with a straight plug, so it will work with the HL10 handset lifter, but it cannot be plugged directly into any of the CS model wireless headsets with the port on the bottom side of the base.
