There are four primary setup options in the analog menu: Themes, Tick

needle style.
There are five gauge settings:
Gauge Style:

Split analog: features two gauge elements and two gauge needles in one
analog gauge. Each element uses one-half of the gauge.

digital gauge.
There are two choices under gauge select. Primary and
