The Kuando Busylight Combi is a “headset in use” indicator. When the light on the top shines red, you are on a call. Additionally, the Combi offers a manual “Do Not Disturb” switch, so you can signal when it’s time for you to concentrate and deflect distractions. The Kuando™ Busylight Combi is designed to help eliminate office distractions and interruptions. In open office environments where headsets are the common practice, you may experience co-workers interrupting you while you’re on a call or during a time where you need to concentrate. Daily distractions and unwanted interruptions result in lost efficiency and poor work quality. Combi effectively and respectfully notifies your surrounding co-workers that you are in a call or need to concentrate without being interrupted. Simply connect it to your Headset, handset, and desk phone, and you’re ready to go!
