The radio is completely adjustment-free and only requires a minimum of small and low cost external components. The radio can be tuned to the European, US and Japanese FM bands. 2004 Sep 13 3 Philips Semiconductors Product specification Low-power FM stereo radio for handheld applications 4 QUICK REFERENCE DATA VCCA = VCC(VCO) = VCCD.
