System Checks
1. Check for proper DC voltage at the power
connector.
2. Momentarily remove and reapply power.
1. Check for secure interface connections at the
transceiver.
2. Check antenna, feedline, connectors, and reflective
power.
3. If remote unit is in synchronization but
performance is poor, it may indicate antenna
problems. Check for properly aligned antenna
headings.
4. Verify proper programming of the system
parameters.
1. Verify that the system has a unique network
address. Nearby systems with same address will
cause interference problems.
2. If Omni-directional antennas are used with the
remote units, consider using a directional type
instead. This will often limit interference to and
from other stations.
3. Check RSSI value at the remote. A low value
would correspond to a weak signal strength.
