Maintenance
Battery Replacement:
When the battery indicator shows low power, replace all three AAA batteries promptly to ensure continuous operation. Follow the battery installation steps in the Setup section.

Winterization:
Before the first frost, disconnect the timer from the faucet and hose. Remove the batteries. Store the timer indoors in a dry, protected area to prevent damage from freezing temperatures.
