LR900 Node
Antenna Requirements
There are a few items to remember about the antenna.
1) Keep the antenna away from metal surfaces for the best RF signal range.
2) For long antenna cable runs, use LMR-400 coaxial cable with adapters.
3) Never exceed 11dbi of antenna gain without some sort of cable loss (FCC
requirement).
Note: If an LR900 is out of range of its group, any LR900 can be used as a repeater to
extend the range of the signals and reach the lone LR900.
Returning to Factory Defaults Using Menu Screen
The LR900's can be restored to their factory default programming at any time by using the
menu screen. Returning to the factory default is the recommend method to recover from
programming errors or other events such as when a unit is not communicating within the
group.
After defaults have been restored, basic communications can be verified and custom changes
can continue from that basic, known state.
