With the two channel JTECH Extend two-way radio, you can partition into two different work groups. For example, Channel 1 - Staff and Channel 2 - Management. Management can monitor both channels and have private conversations with other managers. Extend walkie talkies have a standard 2 watts of power for extended coverage and 64 frequecies. Our radios are engineered to eliminate common break and fall points of comparable units. The components of the Extend line - radios, chargers, batteries and headsets are fully compatible and interchangeable with existing CLS components - with a lower cost and extended functionality.
