Product Summary

The KCH-21R ia a speaker microphone with a full-featured control head, which enables one-hand operation of PTT, volume and channel selection. Designed to be used with the KENWOOD NEXEDGE® NX-5000 Series mobiles, the control head's large, bright 1.74" LCD display makes it easy to do at-a-glance status checks. The 14-character full-color display has 5 lines for customizable menus and icons and the 7-color LED display at the top of the unit can be used for quick visual alerts, even in low light and high noise environments. The KCH-21R has built-in Bluetooth® with HSP (headset) and SPP (serial port) profiles and a powerful built-in speaker with 1W output, supported by active noise reduction.

The KCH-21R was designed in collaboration with our fire service and police customers who asked us for easy, intuitive one-hand operation. Our public safety customers also wanted to be able to remotely control multiple NX-5000 Series RF decks, which many of our customers use in their vehicles to enable full tri-band receive and transmit.
