  §  15.229   Operation within the band 40.66-40.70 MHz.

   (a) Unless operating pursuant to the provisions in § 15.231, the field
   strength of any emissions within this band shall not exceed 1,000
   microvolts/meter at 3 meters.

   (b) As an alternative to the limit in paragraph (a) of this section,
   perimeter protection systems may demonstrate compliance with the
   following: the field strength of any emissions within this band shall
   not exceed 500 microvolts/meter at 3 meters, as determined using
   measurement instrumentations employing an average detector. The
   provisions in § 15.35 for limiting peak emissions apply where
   compliance of these devices is demonstrated under this alternative
   emission limit.

   (c) The field strength of any emissions appearing outside of this band
   shall not exceed the general radiated emission limits in § 15.209.

   (d) 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.
