NOTE If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the
transmitting antenna and the ME EQUIPMENT or ME SYSTEM may be reduced to 1 m. The 1
m test distance is permitted by IEC 61000-4-3.
a) For some services, only the uplink frequencies are included.
b) The carrier shall be modulated using a 50 % duty cycle square wave signal.
c) As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because
while it does not represent actual modulation, it would be worst case.
Recommended separation distances between portable and mobile RF communication
equipment and thermometer
The thermometer is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the devices can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the thermometer as recommended below,
according to the maximum output power of the communications equipment.
