Potential
Interference
View the receive area around each DuoLink as a cylinder. Keep all
interference sources outside of this cylinder.
Common sources of interference include TVs, computer monitors, electric
motors, electrical distribution panels, and some pagers. These types of
devices must be at least ten (10) feet away from the DuoLink, even
through walls and ceilings. Other sources of interference include:
Some newer electric washers and dryers
Electrical panels and fire alarm panels
Time clock systems
Certain types of fluorescent lights with electronic ballasts
Some elevators
Light dimmers
CAUTION: All DuoLinks must be tested prior to use to verify proper
operation. Failure to test the DuoLinks before use can result in system
failure and/or an abduction or elopement. In addition, failure to test
DuoLinks voids the RF Technologies Product Warranty.
