With this compact, flexible USB DECT adapter, you can stay connected up to 150 m away from your laptop and move freely with your laptop during calls. Unlike conventional USB adapters, the Link 400 has a unique flexible design. This makes it more durable and reduces the risk of damage if you leave the adapter connected to your laptop... while you walk around. The Link 400 has a large button for easy one-touch pairing with your Engage headset. The bright, colourful LED indicator lets you manage calls effectively. The LED lights up blue when you're connected, green while you're on a call and red when the microphone is muted. The LED of the Microsoft Teams variant lights up purple when connected to Teams and flashes purple when there are new Microsoft Teams notifications. The Link 400 is certified to the DECT security standard. However, the security of your data is our top priority. That's why the Link 400 goes beyond DECT Security Level C and offers additional 256-bit FIPS military-grade encryption algorithms.
