Turn it off then, you radar won't be able to pickup the low pulse kband used by some nz speed camera's
My old passport max could pick then up wasn't a lot of time to slow down though like ka band.
I sold it on to buy something else and been waiting for the release of the international max2(with bluetooth) but nothing has become available.
I have put my name down for the max360 international presale but it could be awhile before a international model is available.
fwiw the passport max i owned had extremely accurate and fast reaction from the gps signal, once you adjust your speed you can't even count 1 second before the speed changes to what you are doing on the radar.
