5. Maintenance

5.1 Battery Replacement

The remote control is powered by one 12V/27A battery. When the remote's range decreases significantly or it stops responding, it may be time to replace the battery.

Locate the battery compartment on the remote control. This is typically on the back or side, secured by a small screw or a snap-on cover.
Carefully open the compartment.
Remove the old 12V/27A battery.
Insert a new 12V/27A battery, ensuring correct polarity (+ and -).
Close the battery compartment securely.

Note: Dispose of old batteries responsibly according to local regulations.
