Description
The Poly Online Indicator Busy Light (85R52AA, part 80287-01) is a visual status indicator that lights up whenever your wireless headset is active on a call, signaling to nearby colleagues that you're unavailable. It plugs directly into the Savi or CS500 Series headset base using a straight plug and requires no software, drivers, or configuration. In open-plan offices where interruptions during calls are a daily friction point, the Online Indicator is a low-cost, high-impact tool for improving focus and reducing disruptions.
