Immunity aspects at RF
The device is intended for use in the electromagnetic environment specified below. The customer or the user of the device
must ensure that it is used only in such an environment.
Portable and mobile RF communication devices must be used no closer to any part of the device, including the cables, than the
recommended separation distance, calculated from the equation applicable to the frequency of the transmitter.

Field strengths from fixed RF transmitters, as determined in an electromagnetic site survey, should be less than the
compliance level in each frequency range. Interference may occur in the vicinity of equipment marked with the following
symbol:
Recommended separation distance between portable and mobile radio communication devices and
the ALADDIN device
ALADDIN is intended for use in an electromagnetic environment in which radiated RF disturbances are under control. The customer or
the user of the device can help prevent electromagnetic interference by maintaining a minimum distance between mobile and
portable RF communication devices (transmitters) and the ALADDIN device as recommended below, according to the maximum
output power of the radio communication devices.

For transmitters with maximum output powers not listed above, the recommended separation distance d in meters (m) can be calculated
using the equation applicable to the frequency of the transmitter, where P is the nominal maximum output power of the transmitter in
Watts (W) according to the transmitter manufacturer.
Note:
(1) At 80 MHz and 800 MHz the separation distance of the higher frequency range applies.
(2) These guidelines may not be applicable in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
