  Sec.  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  Sec. 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
