Note
: If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the trans-
mitting antenna and the TytoCare Device may be reduced to 1 m. The 1 m test distance is per-
mitted 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.
