OFY-ACM-0001Audit Tire Survey Tools

March 1, 1999 Federal Communications Commission Equipment Authorization Division 7435 Oakland Mills Road Columbia, MD 21046 Subject: Maximum Permissible Exposure calculations for FCC ID: OFY-ACM-0001 To whom it may concern, ACM is submitting a low power transmitter for the Audit-Data and Audit-Air devices. The unit has a low power Transmitter that operates at 916.5 with a radiated output power of .025 mW. Assuming a worst case of no duty cycle. For an Isotropic radiator the surface area of a sphere can be used to determine the area over which the transmitter energy is radiated. Surface area of a sphere = 4*Π*radius 2 In this case where the antenna is an integral part of the unit and cannot be removed. The exposure level can be calculated as follows for the 1.0 dBi antenna gain: MPE distance = (output power*duty cycle*10(antenna gain/10)/(4*Π*Exposure Limit (mW/cm 2 ) 1/2 OFY-ACM-0001 MPE distance = (.025 mW*1*/4*3.14*1) 1/2 = .045 cm = .017 in If you have any questions please do not hesitate to call me.
