DMR-PX · Digital message repeater, through any PA system (Px) or standalone (PxS)
Discontinued. No longer sold; its specifications and documents stay here for systems still in service.
Your message is digitally stored in EPROM at the factory; the DMR plays it through any PA system (Px) or, standalone, through its built-in speaker (PxS). The recording never wears out and is safe through power interruptions. A built-in timer pauses 1 to 99 seconds between playbacks.
