RF CAL message on the Accutech base radio or field unit indicates that the radio is out of calibration. This could be because the radio has lost it's RF calibration data or that the RF frequencies have drifted over time and are no longer within specs.
If a device is showing "RF CAL" and is not communicating properly, there isn't anything that can be done in the field. The Accutech device will either need to be replaced or repaired.
