6.2 SERVICE: SELF CHECK

To open the "SELF CHECK" menu window, select [MENU] -> 9.SERVICE -> 3.RT

SETUP -> 2.SELF CHECK.

When selecting [MENU] -> 1.TEST -> 2.TX SELF TEST, the "SELF CHECK"

window will display detected values that serve as the basis of determining the TX SELF

CHECK to be OK or NG. The conditions for SELF CHECK are the same as those for

TX SELF CHECK. For details, refer to information on page 6-6.

If the detected level does not meet the threshold, it will be displayed in "red," and the

TX SELF CHECK result will be displayed as "NG." However, the detected levels of

"DRV TEMP" and "PA TEMP" are not displayed in "red."

Items not to be checked by the SELF CHECK are left blank. The FS-2575 system has

just a single PA board and no COMB board. Consequently, the PA2 and COMB:

UNBALANCE check items are left blank.
