Information about electromagnetic immunity
Recommended separation distances between portable and mobile
RF communications equipment and the device
The ABO 523 model is intended for use in an electromagnetic environ-
ment in which radiated disturbances are controlled. The customer or the
user of the ABO 523 model can help prevent electromagnetic interfer-
ence by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the ABO 523 model as
recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in meters (m) can be estimated
using the equation applicable to the frequency of the transmitter, where
P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
NOTICE 1 At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
NOTICE 2 These guidelines may not apply in all situations. Electromag-
netic propagation is affected by absorption and reflection from struc-
tures, objects and people.
