Recommended separation distances between portable and mobile RF communications equip-
ment and the handy vaq
The handy vaq is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the handy vaq can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobi-
le RF communications equipment (transmitters) and the handy vaq as recommended below, according to the maximum output power of
the communication equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (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 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.
Note 3:
An additional factor of 10/3 is used in calculating the recommended separation distance to
decrease the likelihood that mobile/portable communications equipment could cause
interference if it is inadvertently brought into patient areas.
