  § 15.225   Operation within the band 13.110-14.010 MHz.

   (a) The field strength of any emissions within the band 13.553-13.567
   MHz shall not exceed 15,848 microvolts/meter at 30 meters.

   (b) Within the bands 13.410-13.553 MHz and 13.567-13.710 MHz, the field
   strength of any emissions shall not exceed 334 microvolts/meter at 30
   meters.

   (c) Within the bands 13.110-13.410 MHz and 13.710-14.010 MHz the field
   strength of any emissions shall not exceed 106 microvolts/meter at 30
   meters.

   (d) The field strength of any emissions appearing outside of the
   13.110-14.010 MHz band shall not exceed the general radiated emission
   limits in § 15.209.

   (e) The frequency tolerance of the carrier signal shall be maintained
   within ±0.01% of the operating frequency over a temperature variation
   of −20 degrees to + 50 degrees C at normal supply voltage, and for a
   variation in the primary supply voltage from 85% to 115% of the rated
   supply voltage at a temperature of 20 degrees C. For battery operated
   equipment, the equipment tests shall be performed using a new battery.

   (f) In the case of radio frequency powered tags designed to operate
   with a device authorized under this section, the tag may be approved
   with the device or be considered as a separate device subject to its
   own authorization. Powered tags approved with a device under a single
   application shall be labeled with the same identification number as the
   device.
