TECHNICAL DATA
11.2.4 Specifications of the Tests for the Immunity of the Accessible
Parts of the Casing to the Wireless RF Communications Device
MICROPIEZO is designed to operate in an electromagnetic environment in which radiated
RF disturbances are under control. The client or operator of MICROPIEZO can help prevent
electromagnetic interferences by guaranteeing a minimum distance between the mobile and
portable RF communication devices (transmitters) and MICROPIEZO, as recommended below, in
relation to the maximum output power of the radio communication devices.

a) For some services, only uplink frequencies are
included.
b) The carrier must be modulated using a square wave
signal with a duty cycle of 50%.
c) As an alternative to FM modulation, 18 Hz pulse
modulation at 50% can be used because, although it
does not represent true modulation, it represents the
worst case.
