Reduced separation distances to portable and mobile radio frequency communication devices
The following separation distances are based on additional tests
performed by Dräger to determine the minimum separation dis-
tances absolutely necessary. These reduced separation distances
are valid only for mobile radio frequency communication devices
using the standards listed.
