Note: If FL##/## (W4,W5,W7) or FAIL ##/## (W9) appears in the
display, the radio will not function until the condition has
been corrected.
If
ER##/## (W4,W5,W7) or ERROR ##/## (W9) appears,
some non-critical data has been changed. If either of these
displays appear, if the display goes blank, or if the unit
appears to be locked up, refer to “Troubleshooting” on
page 130.
