Convenient voice communication with mobile radios.
The wireless remote speaker microphone SM27W1 offers you more flexibility in the use of mobile DMR and TETRA mobile radios from Hytera. Without a bothersome cable, you can communicate as usual via your radio.
Using the wireless speaker microphone, you can even remotely control your MD655, MD785/MD785G or MT680 Plus and, for example, select channels or regulate the volume. In so doing, you move up to 10 meters away from your radio.
For the use with DMR mobile radios, the adapter ADA-01 requires that your radio is connected to the audio accessories connection of your radio. The TETRA mobile radio MT680 Plus by contrast requires no additional adapter.
The supplied bracket is also used for charging the wireless microphone. Alternatively, the supplied charging cable can be connected directly to the SM27W1.
