FP questions (I-485)

The I-485 receipt showed that: 'The next step is to have your biometrics taken at a USCIS Application Support Center. Call customer service at 1.800.375.5283 to schedule your appointment'. I submitted 140/485 later September but I did not recive any notice on fingerprint. Do I need to call USCIS or just wait patiently for their notice?
