TROUBLESHOOTING
For proper operation, all radios in the network must meet these basic
requirements:
• Adequate and stable primary power.
• Secure connections (RF, data and power)
• An efficient and properly aligned antenna system with a
received signal strength of at least –90 dBm. (It is possible for a
system to operate with weaker signals, but reliability will be
degraded.)
• Proper programming of the transceiver’s operating parameters
(see
