The battery system indicates that batteries are almost empty, what should you do? Easy! Fully charge the batteries first. Then see if the flashing light near the batteries (Blincky) flashes green or red.

Green flashing light:
All right, go sailing!

Red flashing light:
Fluid level too low.

1. Connect the supplied pressure vessel. This contains demineralized water;
2. Pump pressure vessel to pressure;
