Solve control-panel display problems
CAUTION: Static electricity can cause unexpected black lines or dots to appear on the product control-
panel display. Do not touch the product control-panel display if there is a chance that you have collected
a static electric charge (for example, by walking on carpet in a low-humidity environment).
Unexpected lines or dots might appear on the product control-panel display, or the display might become
blank if the product is exposed to an electric or magnetic field. To resolve this problem, perform the
following procedure:
1. Turn the product off.
2. Remove the product from the electric or magnetic field.
3. Turn the product on again.
