What does power saving mode do?
In a nutshell: • Disables WAAS • Limits backlighting to 10% for 15 seconds • Slows the processor, which increases redraw times CPU speed reduction does not kick in until 15 seconds after the last button press, so the unit remains responsive when you are actively using it. Other than the loss of WAAS, there is no decrease in accuracy. There is no effect on track logging.
