S1,2 = Pushbutton (S1 = Start and Pause. S2 = Stop and Reset)
S3 = Change-over switch
Hψjttaler = 8R speaker

The 2 pushbuttons = S1: Start/Pause. S2: Stop/Reset.

If you want to play your message, put S3 at Play. Then push S1 to start playing and again to pause.

If you want to delete your message press S2 twice.

If you want to record a message put S3 at Rec. Then push S1 to start and S2 to stop.
