Appendix A: Error Messages

Solution

Connect a detectable antenna (antenna must have some DC resistance).

FAULT_TEMPERATURE_EXCEED_LIMITS – 504h

Cause

The module has exceeded the maximum or minimum operating temperature and will not
allow an RF operation until it is back in range.

Solution

Take steps to resolve thermal issues with module:



Reduce duty cycle



Add heat sink



Use

Power Save Mode (non-DRM Compliant)

FAULT_POOR_RETURN_LOSS – 505h

Cause

The module has detected a poor return loss and has ended RF operation to avoid module
damage.

Solution

Take steps to resolve high return loss on receiver:



Make sure antenna VSWR is within module specifications



Make sure antennas are correctly attached before transmitting



Check environment to ensure no occurrences of high signal reflection back at

antennas.

FAULT_AHAL_INVALID_ANTENA_CONFIG – 507h

Cause

An attempt to set an antenna configuration that is not valid.
