9. Maintenance
The life of the JUE-501/JUE-251 depends on how well the equipment is maintained. Check the
following items from time to time to ensure the best performance of your JUE-501/JUE-251.
1) Keep the input voltage within the specified range (+21VDC to +31VDC).
2) Record the transmitting power (EIRP) and the receiving level (REC) once at the time when the
equipment is in good order. During the operation, compare the EIRP and REC level with the
recorded normal values. This deed helps you to remove a fault before it develops into a serious
one.
