LED Description
Signal Strength If only one of these three LEDs is lit, then the radio is linked. If two LEDs are lit,
the radio’s signal strength is fair. If all three LEDs are lit, the signal strength is
good.
When a repeater or remote is not linked, the LEDs light one at a time in a cycle
from top to bottom. When the repeater or remote is linked, the LEDs light from
bottom to top, with a blinking LED meaning a median signal strength between
the lower LED and the blinking LED.
3.3 Sources of Interference
The RLX2-IFHxE operates more reliably than a radio using conventional
technology due to the frequency hopping spread spectrum technique. While
RLX2-IFHxE radios are less susceptible to interference due to this technique,
interference (radio noise) may still occur. Radios are designed to detect specific
radio frequencies. Interference is an unwanted signal that has been transmitted
at the same frequency that the radio was designed to detect.
There are many man-made and natural sources of electromagnetic interference
(lightning, power lines, switching power supplies, fluorescent lighting, microwave
ovens, cordless phones, and so on). To decrease the effects of interference on
network function:
 Use a directional (high gain) antenna at the Remote radio locations, if
possible.
 Verify that each network operating in close proximity to each other has been
assigned to a different channel.
 Install networks in rural areas (if at all possible) where they will likely
encounter less man-made noise than in urban or suburban areas.
 Enable encryption.
 Change a radio's network output power (refer to the Radio Configuration
screens for each radio of the network):
o Increase power to "drown out" competing noise.
o Decrease power of the radios on the network if they are interfering with
another network in the vicinity.
3.3.1 Changing a Network's Channel
