• LED flashes twice: battery charge between 50% and 80%;
• LED flashes once: battery charge between 15% and 50%;
• LED illuminates directly without flashing: battery almost discharged. Recharge
as soon as possible.
• LED flashing continuously: battery completely discharged; or overvoltage de-
tected (user attempts to connect a different battery from the original). The LED
will remain flashing until the user turns off the sprayer.
When the battery is completely discharged during spraying, the pump automati-
