No inputs detected. Once the Aux battery has
been connected and is within the detectable
voltage range, the battery type LED will short flash
to indicate the device is in standby mode and no
input sources are detected
Battery type selection mode
Press and hold the Mode button for 2 ~ 4
seconds, upon releasing the button, the default
battery type LED will cease to flash and remain
solid. Press mode button repeatedly until required
battery type LED is selected. Battery type setting
is now programed and charger will return to
Standby mode after a short time.
Standby Mode Alternator input detected
With no Solar connected or detected and the
Alternator is the only available input source, the
input LED will short flash to indicate input voltage
is below the set cut-in voltage. Charger is still in
Standby mode and has not begun to charge the
