The channel readout indicates that channel 1 (Ch1) is displayed with DC
coupling. (In AC coupling, ~ appears after the volts/div readout.) The
digitizing oscilloscope always displays channel 1 at reset.
Right now, the channel, time base, and trigger readouts appear in the graticule
area because a menu is displayed. You can press the CLEAR MENU button at
any time to remove any menus and to move the readouts below the graticule.
