Just updated my 9500ix's firmware and now it does the shockingly annoying long startup. The thing beeps for every band before shutting up. Has anyone else had this issue? I can't find the setting to disable it. I vaguely remember the guy who installed it for me (hardwired) changing a setting when I got it a year ago to get it to do the short-start but I couldn't find this setting in Detector Tools or in the menu on the detector itself. If there's no way to disable this, does anyone know how to downgrade firmware?
