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 modulateci using a 50% duty cycle square
wave signal at 18 Hz. While it does noi represent actual
modulation, it would be worst case.
NOTE: If necessary to achieve the
IMMUNITY TEST LEVEL, the distance
between the transmitting antenna and the
PIEZOSURGERY plus may be reduced to 1

WARNING: Portable RF communication
equipment (including peripheral devices as
antenna cables and external antennas) must
not be used closer than 30 cm (12 inches) to
any part of the device PIEZOSURGERY plus,
including the cables specified by the
manufacturer. Otherwise, there may be a
performance degradation of these devices.
