With the ErisStation conference speakerphone, everyone can get in on the conversation - whether they're at the conference table or not. Callers can speak and be heard at the same time, just as they would in a face-to-face meeting. Participants can keep talking up to 150' away from the base. Plus, dynamic noise reduction (DNR), DECT 6.0 technology and a full-duplex speakerphone ensure natural, uninterrupted sound quality. Speakerphone includes four wireless and two fixed DECT 6.0 microphones with Orbitlink Wireless Technology. With 8 hours of talk time for each microphone, you have plenty of room to keep the meeting going on one charge. You won't have to worry about losing a charge during a meeting with up to 70 hours of standby time for each microphone. Magnetic charging bays in the base keep the microphones together and ready for the next call. Speakerphone also features a two-line backlit display with date and time and battery-low indicator with flashing LED.
