5.3. Antenna Output Assignment
NOTICE
If there is no antenna connected to an antenna output then the output should be
disabled. This will make the switching between two available antennas easier and, more
important, it will prevent potentially damaging no-load transmissions.
In order to enable or disable an antenna output, briefly press PREV+NEXT buttons successively until the
"Ant: (1-…) 2-… 3-…" screen appears. Using the ANT button, move the brackets to enclose the antenna
output you want to disable or enable. Press the PREV button to disable or NEXT to enable it.
Press PREV+NEXT briefly again to confirm the antenna output assignments and then leave the menu.
5.4. Reading Auto-protection Signatures
On every HARD FAULT protection trip of the amplifier, signature information is stored in its nonvolatile
memory. The 7 most recent auto-protection trip signatures related to the amplifier internal status are
stored there, which you can copy and forward to your dealer for diagnostics.
In order to read the trip signatures, press the OPER button while OFF LINE. The beginning of the signatures
list will appear. Use NEXT and PREV buttons to navigate through the 7 pairs of screens. For each auto-
protection trip there is a pair of information lines beginning with nA... and nB... where:
• "n" is the successive number of the event (Nr. 1 is the latest, Nr. 7 is the oldest one);
• "A" and "B" mark the first and second parts of an information screen pair.
Two lines, three groups by six symbols (36 symbols in total) are to be copied concerning every one of the 7
memorized events, from 1A-1B through 7A-7B.
To decode the signatures, please, see Section 6.6 Troubleshooting.
After every signature listing the tube warm-up time is reset to 180 seconds regardless of
the time being in OFF LINE state.
