Product Description
UDM-240ZH Wireless Speaker Microphone/Intercom
The UDM Series is a great 2 in 1 communications device that provides reliable, license-free radio communications between palm mics and at the same time, also has the ability to communicate through a mobile radio via repeater connection. This interactive device is ideal for tour groups, speaker presentations, restaurants, job training, in-person consultations, and for anytime you need wireless radio communication outside of your vehicle.
Unlike other listening devices that are receive-only, the UDM lets participants respond using their device as a speaker microphone. As a result, all participants can enjoy an interactive conversation.
The UDM is ideal for high noise situations when combined with one of our receive-only ear pieces. Everyone involved has the ease of casual conversation with high-quality audio. Not only can everyone be heard, but the units have a range of up to 160 feet of communication, allowing the flexibility for everyone to move around in a tour type environment.

The UDM-240ZH package comes complete with the speaker microphone, charger, and 110V power supply.
When our UDM System’s UDM-240ZV repeater is tethered to your vehicle’s mobile radio or office base station, the UDM-240ZH palm mic can function as a tough, wireless PTT mic for the mobile up to 320’ away. While in wireless communication with your mobile radio using one PTT button, you will also have the ability to have a private conversation to other UDM mics 160’ away from each other on a separate PTT button through its “Intercom” mode.
