Ring Tone

 
Dear,

I have received a Silver trend_Signal.My query is what is the additional command in the below file in order to get a beep tone for a seconds in my computer (WinXP2000) whenever we get a Aqua or Violet color in the H4 period.
Thanks in advance for your support.
Best Regards,
jamal Barakat
