GDL 30/30A Owner's Manual

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.
