Note: When using the Chartplotter and GDL 30A on battery power
only (engines off) for extended periods of time, be sure there is enough
available amperage to run the units for the time period. Running other
onboard devices at the same time may lower the available amperage,
causing the Chartplotter and/or GDL 30A to shut off. Check with your
local marine dealer/installer if problems persist.
