Recommended Separation Distances Between Portable and Mobile
RF Communications Equipment and the t:slim System
The t:slim System is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
the t:slim System can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the System 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 determined 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.
