Recommended separation distances between portable and mobile RF
The petMAP gII is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or 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
in meters (m) can be estimated using the equation applicable to the frequency of the transmitter,
the maximum output power rating of the transmitter in watts (W) according to the transmitter
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.
