Not sure what you are looking for, but you can find information on the fan settings here on page 5: http://www.docs.hvacpartners.com/idc/groups/public/documents/techlit/OM05-60.pdf.
If you believe the fan is not working properly to blow heated air through the system you may want to look for the LED error/fault code display on the furnace. If you go here you can find the location of the error/fault code display and a list of what the different codes indicate: http://www.gogeisel.com/geiselonline/support/Bryant/340MAV_350MAV_355MAV_OM.pdf.
I suggest doing this because the problem may or may not be the fan. If the furnace is not heating properly or not getting the call for heat from the thermostat it may affect whether the fan runs or not.
Either way, if you are having problems with the fan you will need a certified HVAC tech to come and fully diagnose and fix the problem. Trying to work on your furnace as a DIY project is not a good idea as it can be dangerous and you could make the problem worse.

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.
