Appendix A: EMC Information
Recommended separation distances between
portable and mobile RF communications equipment and the TAV® system
The TAV® device is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the device 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.
NOTE 1: At 80 MHz and 800 MHz, 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.
