Hook-up & use
*How to play a message :
Press the 'PLAY'-button once to play the message. LD1 will flash once to indicate end-of-message.
*Other features :
Message select : connectors SK3 and SK4 allow you to connect a selector switch (e.g. Velleman 8404-1C),
which allows you to choose between 5 different messages. 'C' is common, 1 to 5 selects message. Max
message length : 4 seconds (x5).
Repeat message : short both pins of SK6 for message auto-repeat.
External pushbuttons : Connector SK5 provides a way to connect an optional 'PLAY'-button at a remote
location.
Pushbutton between 'GND' and 'P-E' : same as the on-board play button
Pushbutton between 'GND' and 'P-L' : same as the on-board play button, but message plays only once,
regardless of the time the button is pressed.
For best results, keep the distance between the button and the board as short as possible (2m (7') max.)
and if possible, use shielded wire.
Line out : Connector SK8 provides a line out, to allow hook-up of an external amplifier e.g. our K2637 or
8
