PM-20EV
The PM-20EV is a convenient addition to sites where the same message or music is repeatedly broadcast. Announcements of up to 6 minutes in length can be recorded and broadcast with easy operation. The USB port facilitates change of internal chimes or announcement messages by transferring the supplied sound sources from a PC to the unit. Recorded messages can be checked before broadcasts, ensuring correct and accurate announcements.
