Sec. 15.225  Operation within the band 13.553-13.567 MHz.

    (a) The field strength of any emissions within this band shall not 
exceed 10,000 microvolts/meter at 30 meters.

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

    (c) The frequency tolerance of the carrier signal shall be 
maintained within <plus-minus>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.
