1.2.1 General Purpose Keys and Knob
The EPOCH 1000 Series provides navigation arrows, [CHECK] and [ESCAPE] keys,
and an adjustment knob (see
Figure 1-3 on page 22). They are general purpose keys,
regardless of instrument mode or function. The [CHECK] and [ESCAPE] keys are
available on both the left and right side of the EPOCH
1000 Series front panel.

The [CHECK] key has three primary functions:
• When a submenu is highlighted, [CHECK] enters this submenu and brings the
highlighted focus to the first parameter within the submenu.
• When an adjustable parameter is highlighted, [CHECK] toggles the parameter
adjustment between a coarse and a fine adjustment.
— Coarse adjustment is active when the parameter title is underlined.
— Fine adjustment is active when the parameter title is not underlined.
• When a parameter button is highlighted, [CHECK] activates that function
(example CAL Zero).
The [ESCAPE] key has two primary functions:
• When in a setup page, [ESCAPE] returns to the live inspection screen.
• When a parameter in the horizontal parameter frame is highlighted, [ESCAPE]
returns focus to the corresponding submenu. A second press of [ESCAPE] returns
focus to the first selection of the first submenu (Basic or PA Display).
