FMTX100
Stereo FM Transmitter with integrated
Audio Processor, Stereo Encoder and RDS Encoder
WARNING!
This Transmitter 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.

RF Power (using the rear panel RF ADJ control) to the desired level, not exceeding 125W. Operation The FMTX100 is designed for continuous reliable transmission, however the fans must be periodically checked for correct operation and free airflow. The front panel display shows the transmission frequency, forward... - Page 10 Correct operation is confirmed by a front panel green STATUS LED. Should this turn red, the transmission system may shut down its RF output and will, in any case, require URGENT attention. The LCD display shows all main parameters so no further menus are provided or required (except frequency setting detailed above).
