TROUBLESHOOTING

Successful troubleshooting of the radio system requires a logical
approach. It is best to begin troubleshooting at the master unit, as the rest
of the system depends on the master for polling commands. If the master
unit has problems, the overall operation of the network will be affected.
It is good practice to start by checking the simple things. For proper
operation, all radios in the network must meet these basic requirements:
• Adequate and stable primary power
• Secure cable connections (power, data and Antenna)
• An efficient and properly aligned antenna system and a received
signal strength of at least –90 dBm. (It is possible for a system to
operate with weaker signals, but reliability will suffer.)
• The correct interface between the transceiver and the connected
data equipment (correct cable wiring, proper data format, timing,
etc.)
• Proper programming of the transceiver's operating parameters.
Table 14 provides suggestions for resolving system difficulties that may
occur in the radio system. If problems persist, contact the factory for fur-
ther assistance. Refer to the inside back cover of this guide for contact
information.
