Due to numerous different applications, it is reasonable that users are not always aware of parameters of
all components in a SATEL-TA35 radio modem system. However, obeying the safe distances in the table
below, every user can easily fulfil the Canadian authority limit (depends on the frequency in use) for
human exposure to radio frequency radiation in general public use.
