Note:
If necessary, the distance between the transmitting antenna and the ME unit or ME system can be reduced to 1 m
in order to achieve the immunity test level. The 1 m test distance conforms to IEC 61000-4-3.
(a) For some radio services, only the frequencies for the radio link between the mobile communication device and
the base station (en: uplink) have been recorded in the table.
(b) The carrier must be modulated with a square-wave signal with 50% duty cycle.
(c) Alternatively to the frequency modulation (FM), a pulse modulation with 50% duty cycle at 18 Hz can be used,
as this, if not the actual modulation, would represent the worst case.
11.4 Working clearances
The UNIT is intended for operation in an electromagnetic environment,
where radiated RF interference is checked. The customer or the user of
the UNIT can help prevent electromagnetic interference by maintaining
a minimum distance between mobile RF communications equipment
(transmitters) and the UNIT - depending on the maximum output power
of the communication device, as shown below.
