WARNING!

This Transmitter is capable of generating high RF potential.
Touching internal parts, or the connected antenna system, will
cause serious RF burns. Antenna systems should be installed
such that exposure by any person to RF fields cannot exceed safe
limits. The permitted limits vary from country to country. Expert
advice should be sought about the safe installation of this
transmission system.

RISK OF FIRE!

RF (Radio Frequency) energy could cause ignition of combustible
surfaces during fault conditions. Installation should be left to
qualified personnel. RF can cause burns to skin. Ensure antenna
systems and feeder cables are not situated near, or could fall
onto, any combustible surface.
