7.1.1.3 Possible Errors during Calibration
To get the specific error of a faulty calibration process it is necessary to enter the error list of
the radio.
The following 3 errors are related to the calibration process.
LOW RXREF LEVEL:
This error message indicates that the output power of the frequency standard is too low.
Please increase the output power of the frequency standard or use a frequency standard that
meets the required specification.
WRONG REF FREQ:
This error message indicates that it was not possible to perform a calibration with the fre-
quency form of the frequency standard. It should be checked if the output frequency of the
frequency standard is set as Rx frequency at the radio. Please retry the calibration; if the er-
ror appears again, the radio or the frequency standard is defective. Under this condition
please contact the service.
REFTUNE LIMIT:
This error message indicates that the limit of the tuning range was reached and it was not
possible to find valid calibration values. Provided that the output frequency of the frequency
standard is set as Rx frequency at the radio and the frequency standard meets the required
specification, the radio may be defective. In this case please contact the service.
