If necessary to achieve the immunity test level, the distance between the transmitting antenna and the Medical Electrical
Equipment or 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, the carrier may be pulse modulated using a 50 % duty cycle square wave signal at 18 Hz.
While it does not represent actual modulation, it would be worst case.

Electromagnetic environment – guidance
level
Field strengths from fixed transmitters, such as base stations for r adio
(cellular/cordless) telephones and land mobile radios, amateur r adio, AM and FM
radio broadcast and TV broadcast, cannot be predicted t heoretically with
accuracy. To assess the electromagnetic environment d ue to fixed RF
transmitters, an electromagnetic site survey should b e considered. If the
measured field strength in the location in which t his product is used exceeds the
applicable RF compliance level above, t his product should be observed to verify
normal operation. If abnormal p erformance is observed, additional measures may
be necessary, such a s reorienting or relocating this product.
Interference may o ccur in the vicinity of equipment marked with the following
symbol:
Portable and mobile RF communications e quipment should be used no closer
than 30 cm to any part of this p roduct including cables.
