Safety Precautions
Device safety
Before operating a device, check the electrical connection of the device to ensure that the device is securely
grounded.
Electrostatics produced by human bodies may damage electrostatic-sensitive components on boards, for
example, a large-scale integration (LSI). Therefore, take proper safety measures, such as wearing an
electrostatic discharge (ESD) wrist strap or ESD gloves, to avoid damage to the components when operating
the boards.
When operating storage batteries, take steps to prevent battery short circuits and electrolyte overflow or
leakage. Electrolyte overflow may corrode metal parts and boards, and ultimately cause equipment rust or
board short circuits.
Corrosion
Anti-corrosion measures are required if an RTN 980L is installed in a location that is prone to corrosion. Contact
your local Huawei office for details. A location is prone to corrosion if it is:
Within 3.7 km ( 12139 ft ) of an ocean or a salt water lake
Within 3 km ( 9843 ft ) of a heavy pollution source, such as a smelting factory or coal mine
Within 2 km ( 6562 ft ) of a medium pollution source, such as a chemical, rubber, or electroplating plant
Within 1 km ( 3281 ft ) of a light pollution source, such as a food or leather processing plant or industrial boiler
Microwave
High-power radio frequency signals are harmful. Avoid exposure to transmissions from the antennas of
microwave equipment that has the radiation warning symbol
. When you are installing or performing
maintenance on an antenna located on a tower that has multiple antennas, be careful not to exposure yourself
to radiation from the other antennas.
IF Cable
Before installing or removing an IF cable, turn off power switch.
