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 injection system unless
a greater separation distance is required as indicated by the equation. Otherwise, degradation of the
performance of this equipment could result.
CAUTION: System may disarm or fail to operate when exposed to high magnetic fields. Portable and mobile RF
communications equipment can affect the system.
Recommended separation distances between portable and mobile RF communications equipment and the system
The System is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the 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.

transmitter (W)

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.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and
people.
