1 Safety Precautions
PLEASE READ THESE SAFETY PRECAUTIONS!
RF Energy Health Hazard
This symbol indicates a risk of personal injury due to radio frequency exposure.
The radio equipment described in this guide uses radio frequency transmitters.
Do not allow people to come in close proximity to the front of the antenna while the transmitter is
operating. The antenna will be professional installed on fixed-mounted outdoor permanent structures to
provide separation from any other antenna and all persons.
WARNING: RF Energy Exposure Limits and Applicable Rules for 6-38 GHz. It is recommended that the
radio equipment operator refer to the RF exposure rules and precaution for each frequency band and other
applicable rules and precautions with respect to transmitters, facilities, and operations that may
affect the environment due to RF emissions for each radio equipment deployment site.
Appropriate warning signs must be properly placed and posted at the equipment site and access entries.
Protection from Lightning
Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio and
television lead-in cables must have adequate surge protection at or near the point of entry to the
building. The code specifies that any shielded cable from an external antenna must have the shield
directly connected to a 10 AWG wire that connects to the building ground electrode.
Do not turn on power before reading documentation. This device has a -48 VDC direct current input.
Protection from RF Burns
It is hazardous to look into or stand in front of an active antenna aperture. Do not stand in front of or
look into an antenna without first ensuring the associated transmitter or transmitters are switched off.
Do not look into the waveguide port of an ODU (if applicable) when the radio is active.
Risk of Personal Injury from Fiber Optics
DANGER: Invisible laser radiation. Avoid direct eye exposure to the end of a fiber, fiber cord, or fiber
pigtail. The infrared light used in fiber optics systems is invisible, but can cause serious injury to the
eye.
WARNING: Never touch exposed fiber with any part of your body. Fiber fragments can enter the skin
and are difficult to detect and remove.
