The Display Settings submenu lets you adjust the screen brightness level and control the auto-dimming function. Refer to Brightness Settings Menu.

You can also turn off the display entirely, as described in Display Settings Menu. To turn the display back on, press any key (except the Power button) three times in rapid succession.

In addition to the default display colors shown in Figure: Cable & Antenna Analyzer Return Loss Measurement Display, you can select different color schemes to suit the ambient lighting conditions. See Figure: Cell Master Display Color Settings. Some color settings may not be available in all measurement modes.
