30Erasing the nonvolatile memory (see S.6-6) will blank the CALL sign message until the text isreprogrammed following the procedure described above.6-2 AUTO ANTENNA CHANGEWhen YES is selected, changing frequency segments (manually or following the transceiverfrequency or by CAT - S.4-1c), will cause the antenna last used in the respective segmentand the tuning settings for it to be selected. This is convenient when you have 1 or 2antennas for each band. With more antennas you would have to keep track of whichantenna you used last.If "NO" is selected, this function is disabled and the currently used antenna is changed onlyafter an intentional command is given for an antenna change (manually or via the localnetwork - see S.4-1d). When changing frequency segments, the tuning settings for theantenna currently used will be selected in the new segment. This mode is preferred whenyou have multiple antennas per band.Selection of YES or NO does not change any contents for tuning settings in the nonvolatilememory.6-3 AUTO OPERATESet to "OFF" by default.When “ON” is selected, the amplifier will remain ready to operate, even automaticallyreturning from standby after a soft-fault protection trip. That is, after a protection trip, e.g.from an overdrive event, the amplifier will normally shift to the STB mode for about fourseconds, but it will automatically return to the OPR mode after that. Even with ON selectedhowever, you still may depress the OPR hardware button manually to go to and remain in theSTB (Stand By) mode at any time, such as when you leave the station for a while.If “OFF” is selected for AUTO OPERATE, the amplifier will go and remain in the STB modeafter a soft fault until switched over to the OPR mode manually by the operator or anintended command is received via the local network.6-4 SELF ADDRESSHere you can set the amplifier self address for operation in a network with other systems.When the amplifier is not used in a network, this address is meaningless.6-5 CLEAR THE USER TUNINGSN O T EIf you use this function, it is advisable that you update the USR tunings (seeS.4-1).When selected “YES”, this function clears all USR-tunings from the nonvolatile memory butdoes not change anything else in the INFO-BOX.The use of CLEAR THE USER TUNINGS is convenient when the amplifier is moved toanother operating place to prevent from mixing with the remaining USR-tunings which arevalid for the antennas at the old location. Of course, if the total number of antennas is lessthan 10 per segment, you can do USR-tunings with new antenna numbers and thus preservethe USR-tunings for the antennas at the old location as well.
