3.4. Basic Screen
The following information areas are to be distinguished on the basic screen:
a) Information area for the frequency band
Please, see Figure 3-2 | Basic screen, Pos. (a).
The edges of the currently selected BAND are displayed. If the amplifier does not receive any operating
frequency data from CAT or via RS-232, it will switch to the last used band.

b) Operating values and alarm messages area
Please, see Figure 3-2 | Basic screen, Pos. (b).
Any two operating values selected in the AMP MEASURE menu will be shown here (see Section 5.1 Menu AMP
MEASURE (Amplifier Measurements)).
The alarm messages (either WARNING or SOFT FAULT) appear on yellow background on the same area and
are flashing frequently in order to attract the operator's attention (see Figure 4-4 | Appearance of an alarm
message).
The WARNING messages appear only temporarily (for about three seconds), afterwards the indication of the
operating values is restored automatically (see Section 4.5.a) First protection level - WARNING).
The SOFT FAULT messages appear in the same field but they remain on the screen until the AUTO OPERATE
time is elapsed (see Section 4.1.c) AUTO OPERATE user setting) or until the operator pushes any button, then
the operating values (regime measurands) indication is restored too.
