Pattern 4 Target error code: U508,U513
The touch-screen, handswitches, footswitch pedals, and push buttons
are available.
Do not press the “OK button”, but proceed to the remedial actions on the
error window or of “What to do when an error code is displayed”.
If the “OK button” is pressed without taking the remedial actions, the
error window disappears even when the error is not cleared.
After taking each remedial action, be sure to perform the operation in
Section 5.7, “Verification of the high-frequency (RF bipolar) output
(when using the THUNDERBEAT)” in Chapter 5, “Inspection”.
When the error window is not displayed after inspection, the error has
been cleared.
If the error window is still displayed, the error is not cleared. Take the
next remedial action.
