3.3.4 Diagnostic Help
Selecting DIAGNOSTICS from the MAIN MENU
presents a list of ITEMS from the top level of the DIAG-
NOSTICS tree.
When Present Status is highlighted, the highest
MAGNETROL priority active diagnostic indicator (numer-
ically lowest in Table 3.3.3) is displayed on the bottom
LCD line, which is “OK” as shown at left. Pressing the
ENTER key moves the active diagnostic indicator to the
top line outdented and presents in the lower area of the
LCD a brief explanation of and possible remedies for the
indicated condition. A blank line separates the explanation
from the remedies. Additional active diagnostic indicators,
if any, appear with their explanations in descending priority
order. Each additional active indicator name-explanation
pair is separated by a blank line from the one above.
If the explanation and remedy text (and additional name-
explanation pairs) exceeds the available space, a
appears
in the rightmost column of the last line indicating more text
below. In this situation, the DN key scrolls text up one line
at a time. Similarly, while text exists above the upper line of
the text field, a
appears in the rightmost column of the
top (text) line. In this situation, the UP key scrolls the text
down one line at a time. Otherwise the DN and UP keys
are inoperative. In all cases the ENT or DEL key reverts to
the previous screen.
When the transmitter is operating normally and the high-
light cursor is positioned on Present Status, the bottom
LCD line displays “OK” because no diagnostic indicators
are active.
