NOTE: When using the Chartplotter and GDL 30/30A 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 30/30A to shut off. Check with your local marine dealer/installer if
problems persist.
