Got to clark-mode.com, read the manual.

Well thats rude .I have read the maual from clark model.com . I thought this forum is for help ...

The switch that fires the canon is the VRB roller switch on the very top right of the radio. You pull the round switch one direction and the MG will fire, push it the other way and the canon will fire. The VRA round switch on the top left should have another MG sound when you use it, but it only has the MG and nothing else.
If you are having an issue with it firing at weird times, I would go back through the radio configuration from here and verify everything is correct.

I got an answer without an airsoft gun connected , bthe speaker will not make sound because its waiting for a trigger signal from the gun . Thank you guys for your help.

I connect a Henglong recoil BB AIRSOFT and now the speaker makes firing noise for cannon. Very cool.
