Battery installation
1. Remove the battery compartment cover on the back of the RC.
2. Insert the batteries into the battery compartment making sure that the correct
polarity is observed.
3. Install the cover back.
Use two AAA/1.5V batteries for the RC. The RC should be pointed at the IR sensor
within 8 meters and within 30 degrees at the left or the right side.
Take the battery out of the RC if it is not used for a long time.
Do not mix new and used batteries or different types of batteries. Weak batteries
can leak and severely damage the RC
