change BRKC-180 triggering voltage

Hi,
I've bought a BRKC-180; I need to change the triggering voltage.
I've read in another forum that is possible by chenging a resistor:

Someone can help me?
Thank you

Hi, I've attached the resistor values vs the trigger voltage levels chart.

Thank you for the chart.
can you show me which resistor need to be replaced on the board?

Thank you.

Those are the 2 THT resistors on the board closely next to eachother, all other resistors are SMD if I recall.
