Appendix I. Phone to RF401 Series
If there is a neighboring RF401 network, you should change the
Hopping Sequence of base and remote RF401s to a new setting to
avoid interference.
- RX LED Test -
To determine if there is a neighboring RF401 network in operation
using the same hopping sequence as yours, stop communications on
your network and observe RF401 green LEDs for activity. At this
point, any green LED activity would indicate that there is a nearby
network using the same hopping sequence.
