Safety precautions
WARNING!
•
Installing antennas carries some level of risk. For your safety, read the following safety
precautions carefully before your operation.
•
Keep the antenna away from power sources, street lamps, power distribution boxes, or other
places that might cause electrical shock.
•
Do not touch any power lines for your safety.
•
Keep safety in mind when you select your installation site. Keep away from electric power lines
and other lines.
•
Do not work alone when you install the antenna.
•
To avoid any potential hazards, always have a professional handle power connection rather
than attempting it yourself.
•
If an accident, for example, electrical shock, occurs, immediately call for qualified emergency
help.
Installation guidelines
The ANT-2503C-S4 is designed to be mounted indoors on a ceiling to maximize its omnidirectional
propagation.
Install multiple antennas where necessary because doors, windows, and walls degrade signal
quality.
Keep the antenna away from metal obstructions and wire mesh.
