  § 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.
