Trouble stopping the sound in Netwatch after updating the latest version of Microtech

(Down) A sound sounds when a ping is interrupted
(Up) The sound stops when you ping


Down:
:global LIVEBOX1 value=[:tobool true];
:while ($LIVEBOX1) do={
:for i from=1000 to=3000 step=80 do={:beep length=10ms frequency=$i; :delay 10ms;}
:for i from=1000 to=2800 step=80 do={:beep length=10ms frequency=$i; :delay 10ms;}
:for i from=2800 to=1000 step=-80 do={:beep length=10ms frequency=$i; :delay 10ms;}
}

Up :
:global LIVEBOX1 value=[:tobool false];

After the microphone update, the sound no longer stops
It is now sounding down, but the sound does not stop when the "up"
