Midian Electronics now offers the TRC-700 tone remote controller with Pulse Tone (1500 Hz or 2805 Hz) encode and decode capabilities for hospital HEAR systems. The TRC-700 at the hospital can be selectively called by an ambulance to alert them of the emergency. Midian’s UED-1B-DMV can be installed in the ambulance to dial the Pulse Tone. Different microphone configurations are available including the standard internal microphone, optional gooseneck microphone, or handset and cradle.
