A common use for the AR-2000 can be found in systems requiring playback of phrases at fixed intervals triggered from an external timing device (Public Address Systems for example). These particular set-ups use control signals from a timer sent to the AR-2000 to trigger playback of phrases. The AR-2000 is programmed to advance to the next phrase after it receives the control signal from the timer. The control signals sent to the AR-2000 from a timing device are interfaced via its Barrier Strip. Use the following procedure to program the AR-2000 for playback and connection for this configuration:
NOTE: You will need to have a PC card inserted into the AR-2000 before programming. You can playback phrases recorded on a card formatted on either an AR-100 or an AR-2000.
