4-5. Erasing USR segments (return to DEF- tunings)
If you wish to clear a USR setting for a frequency segment and/or antenna, there are two ways this can
be accomplished:
a) to clear all memorized USR-tuning settings - the procedure is described in S.5-5.
b) for separate segments and/or antennas:
z select the segment and antenna for which you want to erase the USR-tuning (see S.4c,d).
z press and hold the button, and press , while still holdng . Then release them at the same
time:
if now you press again, you will erase the USR-tuning for the selected segment and antenna. If,
however, you press
or do nothing for more than 10 seconds, the operation will be cancelled. The
result is reflected in the lower right-hand side corner of MAIN MENU: DEF or USR for the respective
segment and antenna.
5. OFF-MENU
There are 6 sub-menus that can be selected (see also S.3):
5-1. HELP
By means of the and buttons query the Revision Code of the firmware, the Running Time of
tubes, the Serial Numbers of RCU, Amplifier, and Tubes (front and rear), as well as the Safety Instructions
and the most important rules for operating the amplifier.
5-2. CALL
By means of the , , and buttons you can select any arbitrary 9-character text to appear
in the OFF-MENU (for example your own CALL SIGN). The
and buttons select the character
in the position indicated by the cursor (the characters are in an alphabetic order by the ASCII-code).
The
and buttons move the cursor left or right to select different character positions.
Erasing the nonvolatile memory (see S.5-7) will cause the CALL message to revert to the default setting
“A C O M 2 0 0 0 A” or the distributor's name, until the text is changed following the procedure
described above.
