The EPOS HSL 10 II Handset Lifter is a mechanical accessory designed to provide convenient remote call control for desk phones when used with compatible EPOS | Sennheiser wireless headsets and base stations. It allows users to automatically answer and end calls even when away from their desk, significantly enhancing mobility and productivity. Connected to a compatible wireless base station (such as DW Office, VMX Office, and DW900 series), the HSL 10 II responds to commands sent directly from your wireless headset. By pressing a button on the headset, the lifter will automatically raise or lower the telephone handset, enabling remote call pickup or hang-up. This intelligent gadget can also be trained to recognize your phone's ringtone, transmitting the ring signal directly to your wireless headset, so you're notified of incoming calls even if you're out of audible range. It is suitable for a wide range of EPOS | Sennheiser wireless DECT headsets, including the SDW 5000 series.
