Recommended separation distances between portable and mobile RF communications equipment
and the SmartBag System
The SmartBag System is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the SmartBag System can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the SmartBag System as recommended below,
according to the maximum output power of the communications equipment.
WARNING: Portable RF communications equipment (including peripherals such as antenna
cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the
SmartBag System, including cables specified by the manufacturer. Otherwise, degradation of the
performance of this equipment could result.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance
d
in metres (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.
Note 1
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
