1.4 Safety Considerations
Potential safety hazards exist unless proper precautions are observed when working with this
unit. To ensure safe operation, the user must follow the information, cautions, and warnings
provided in this manual as well as the warning labels placed on the unit itself.
1.4.1 High Voltage Hazards
Only qualified service personnel should service the internal electronic circuitry of the Compact
Outdoor Amplifier. High DC voltages (300 VDC) are present in the power supply section of
the amplifier. Care must be taken when working with devices that operate at this high voltage
levels. It is recommended to never work on the unit or supply prime AC power to the unit
while the cover is removed.
1.4.2 RF Transmission Hazards
RF transmissions at high power levels may cause eyesight damage and skin burns.
Prolonged exposure to high levels of RF energy has been linked to a variety of health issues.
Please use the following precautions with high levels of RF power.
● Always terminate the RF input and output connector prior to applying prime AC
input power.
● Never look directly into the RF output waveguide
● Maintain a suitable distance from the source of the transmission such that the
power density is below recommended guidelines in ANSI/IEEE C95.1. The power
density specified in ANSI/IEEE C95.1-1992 is 10 mW/cm
2
. These requirements
adhere to OSHA Standard 1910.97.
● When a safe distance is not practical, RF shielding should be used to achieve the
recommended power density levels.
