Built to the same strict standards for ruggedness and reliability as ASL’s renowned analog beltpacks, the DS 290 offers all the features expected in any high-quality 2-channel unit: separate TALK, and CALL buttons, separate volume controls, MENU button, separate activity indicators, and a factory option for use with binaural headsets. The DS 290 applies advanced digital technology for a higher level of performance and unprecedented user utility. The DS 290’s ability to receive text messages can prove critical when essential information must be given before all users are at their stations, or when audible interruptions are not possible. Also, the Person-to-Person (PTP) call capability allows critical or unexpected point-to-point communications to go through without interrupting communications on a regular group channel.
