down menu will indicate a level of up to +46dBm the level remains constant at +43dBm as the maximum. Refer
to Table 3.
GUI Channel Configuration Overview page
When an 8-Ch combiner filter unit has been fitted in either the uplink or downlink or both, the provided tick box
needs to be activated “per channel” feeding through the 8-Ch combiner filter unit in order for the maximum
output power to be auto-adjusted. This will effectively reduce the maximum output power setting of the RFBE to
+ 40dBm from +46dBm which will cater for up to 6 combined channels.
Should the user wish to manually adjust the maximum output power level, Table 3 will indicates the MAXIMUM
output power level setting permissible without causing damage to the 8-Ch Combiner Filter Unit.
