For some services, only the uplink frequencies are included.
b
The carrier shall be modulated using a 50 percent duty cycle square wave signal.
c
As an alternative to FM modulation, 50 percent pulse modulation at 18 Hz may be used because while it does not represent
actual modulation, it would be worst case.
WARNING
Portable RF communications equipment (including peripherals such as antenna cables and external
antennas) should be used no closer than 30 cm (12 inches) to any part of the device, including cables specified
by the manufacturer. Otherwise, degradation of the performance of this equipment could result.
The minimum separation distance for higher immunity test levels shall be calculated using the followin
equation: , where P is the maximum power in watts (W),d is the minimum separation distance in meters [m),
and Fis the immunity test level in V/m.
