Viking Microcassette Recorder DVA-2WA 사용자 설명서

This application is ideal for situations in which a momentary contact
closure will trigger the announcement or message.  Once triggered,
the unit will play its entire message.  When the message has finished,
the switch can be activated again to play the next message (or repeat
the first message if only one is recorded).

a.  Connect speakers to DVA-2WA as shown.

b. Connect “Remote Trigger Switch/Button.”

This application is ideal for situations in which a single switch or but-
ton is used to start and stop the message.  

a.  Connect speakers to DVA-2WA as shown.

b. Solder a momentary SPST switch/button to “REMOTE SW” pads

1 & 2.  This will allow users to start and stop messages from a 
single remote switch.

When installing multiple DVA-2WA’s in displays that are close enough together to cause audible interference, the
I.O. communication will allow only one DVA-2WA to announce at a time. The last unit to be triggered will announce
its message, disabling any current messages played from any previously triggered DVA-2WA.

a.  Connect speakers and remote momentary switches to DVA-2WAs as shown in sections 1, 2 or 3 above.
b. Connect I.O. Com connections as shown to prevent two announcers from playing at one time.
c. A remote ”stop” switch can be connected to I.O Connections A & B.  A momentary closure will stop message.
