7. CONFIGURATION
A RF Unit is configured via an NMS (Network Management System). To configure
the RF Unit, consult the NMS manual.
8. INCIDENTS
The repeater must be repaired by authorized technical personnel only. If a RF
Unit failure occurs, the entire RF Unit must be replaced. If transmitter module
is damaged and there is not an entire RF Unit available to replace, set RTX
P25 and RPA P25 modules previously calibrated jointly. In last case and if is
not possible to carry out one of the two previous options, replace one of these two
modules and make the gain calibration again.
If an error or alarm occurs in the RF Unit, this is indicated in the corresponding
LED for each one of the modules. The following list shows the possible failures and their
solutions.
