CONTINUOUS GLUCOSE MONITORING SYSTEM
Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and Seven Receiver
e Receiver is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. e customer or the user of the Receiver can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the Receiver 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 manufacture.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: ese guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
