FMAMP250
Broadcast 250W RF Amplifier
WARNING!
This RF Amplifier is capable of generating extremely 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.
