5 Troubleshooting

Here are some tips to help resolve issues when operating the RCL220.
Symptom
Radio is alarmed (PWR LED is flashing)
Alarm: GPS PPS Not Available
Alarm: GPS Signal Inverted
Alarm: NMEA Data – Invalid
05-XXXXA01 Version 3 Draft
Possible Cause
Check the alarm list accessible from the Starting
Information Screen.
Radio is not receiving a PPS.
Although a PPS has been detected, it is in the
ACTIVE state for more than a half of a second. Try
switching the PPS Polarity setting on the GPS
Configuration Menu.
The radio is not receiving valid NMEA GGA
Sentences. Verify that the NMEA Baud rate is set
correctly and verify that the GPS is outputting
ASCII GGA sentences (and no others, if possible).
