The tach graph screen and a big animated bar graph. The graph defaults to
max out at 9000 RPM, but you should customize it to match the maximum
RPM of your vehicle. This way you can get the full range of graph motion.
Use the tumblers to select the max value for the graph, then tap Ok to save
the choice.
Charge Mode Help
Voyager Pro usually charges up it's internal battery whenever it is connected
to power. However, if Voyager Pro is wired directly to the vehicle battery
(instead of behind a key switch) then the vehicle battery may be drained. In
that case to avoid draining the vehicle battery, set Voyager Pro to only
charge when the engine is running (i.e. a tach signal is active.)
