1.6 How it Works
The GuardianA amplifies signals that reach a building from the nearest radio tower, and from radios inside the building going
back to the tower. This compensates for weak reception caused by distance, topography, building structure, etc. The BDA
receives the signal from an outside antenna, amplifies that signal, and then rebroadcasts it via antenna(s) inside the building,
where it can then be picked up by radios inside. In the reverse direction, interior antennas also pick up signals coming from
radios, where they are amplified by the BDA, and then passed to the exterior antenna for rebroadcast back to the tower.
1.7 A Word About Safety
Follow all safety precautions in this manual. This information is designed to prevent personal injury, equipment malfunction,
and/or radio interference. You are responsible for ensuring a safe installation.
Your installation may require working in high locations such as roofs and/or ladders. Follow applicable safety regulations and
best practices to avoid falling. Take care not to drop objects from any high area. Cordon off ground areas directly below the
section of roof you are working on, or below your ladder whenever possible.
In addition, as a qualified installer, you are responsible for knowing and following all applicable codes and regulations and for
obtaining all required permits and inspections.
Always use appropriate personal protective equipment such as goggles, gloves, hard hat, etc. as needed, and as required.
Failure to exercise caution when working in high areas could cause a fall and personal injury.
