Display shows voltage in
between 10.5-11.0 volts.
Display shows .
12 volt voltage is too high.
Display shows . Device
demands more than the converter's

Display shows . Converter
is too hot.
Cycle the converter power OFF
and ON. If problem persists, use a
larger converter or a smaller device.
Remove the defective device.
Recharge/replace battery.
12 volt battery is low. Recharge/
replace battery. The converter will
automatically shut off after battery
voltage reaches 10.5-volts.
If in a vehicle, repair/replace the
alternator or charging system. Use
a properly sized and rated 12 volt
battery. If the input voltage returns
to 15 volts or less, the converter
will automatically restart.
Cycle the converter power OFF
