RX75 Fuse Amp Size

I'm installing a used Beltronics RX75 and I have everything installed except I'm missing the Fuses. I've tried the owners and install manuals but they don't say what size to use. Does anyone know how many amp's I should use for the radar detector and also for the amplified speaker? I don't want to guess and end up frying the detector.

Thanks! :D

I just checked, 2 amp for both. I've got one (mine's an RX75 Plus) brand new in the box, minus the display, that I've got exactly $10.98 in:D:D. Anybody with a display they can't stand to own??
