Any way to have pack light and sound on without wand on?

[Scrap911]

Hello, not being a programmer, all my attempts have not been conclusive.

I would like it if when I turn on my pack (switch on booster), without touching the wand switch, the pack lights as well as the startup and idle sound are active. And then by activating the wand switches, it remains as it is already programmed. In the film when the pack is activated there is the sound of activation, and it is repeated when the wand is armed.
I don't know if I'll have an answer, but I'll give it a try. THANKS
