RF HAZARD PRECAUTIONS
RF HAZARD BACKGROUND INFORMATION
The following WARNINGS should be observed when using your MFJ-9234
MINI LOOP TUNER
TM
:
ACUTE INJURY WARNING
DO NOT touch or make skin contact with the Loop
Connectors or Loop Antenna Wire while transmitting
YOU Could BE SERIOUSLY INJURED !!!
The Hi-Q MFJ-9234
Mini Loop Tuner
TM
can yield
DANGEROUS
RF-voltage potentials during normal
operation. Even at low QRP power levels, the resonant loop circuit can produce RF voltages capable
of causing extremely painful RF-burns on unprotected skin! When tuning or transmitting,
always avoid
skin contact
with the loop connectors and unjacketed loop wire. Also, avoid exceeding the
recommended power limitation (25W). RF burns can be exceptionally painful and slow to heal!
EXCESSIVE RF-EXPOSURE NOTICE

FCC Guidelines
for Human Exposure to
Radio frequency (RF) Electromagnetic Fields
What Is Radio Frequency (RF) Radiation?
Radio frequency (RF) energy is one form of electromagnetic energy. Electromagnetic waves and
associated phenomena can be discussed in terms of energy, radiation or fields. Electromagnetic
"radiation" is defined as waves of electric and magnetic energy moving together (i.e., radiating)
through space. The movement of electrical charges generates these waves. For example, the
movement of charge in a radio station antenna (the alternating current) creates electromagnetic
waves radiating away from the antenna and intercepted by receiving antennas. Electromagnetic
"field" refers to the electric and magnetic environment existing at some location due to a radiating
source such as an antenna.
