Hi! This will be my first post on the website. I have a Federal PA640 siren that has a working manual and airhorn tones but the WAIL, YELP and PRTY modes doesnt work....whenever I turn the selector knob, the unit chirps but no tones come out of the speaker even if the slider switch is placed on position 1,2 or 3. Also tried changing the dip switch positions but I still have the same problem....has anyone encountered similar problems before? I'm currently in the Philippines so I can't phone in FedSig. Thank you
