Clr; Def (Defaults) - Acom 2000R Operating Manual

5-5. CLR

If you use this function, it is advisable that you update the USR tunings (see S.4-1).
This function clears all USR-tunings from the nonvolatile memory but does not change anything else in
the INFO-BOX. The function is activated by pressing the
sub-menu.
The use of CLR is convenient when the amplifier is moved to another operating place to prevent from
mixing with the remaining USR-tunings which are valid for the antennas at the old location. Of course,
if the total number of antennas is less than 10 per segment, you can do USR-tunings with new antenna
numbers and thus preserve the USR-tunings for the antennas at the old location as well.

5-6. DEF (Defaults)

In this sub-menu you can vary the operating mode of the amplifier to cope with abnormal mains voltage,
set the local network self address of the amplifier, and change the antenna selection mode. Once DEF
