slowly or not at all, check the wheels for lint, threads, hair,
dust or other foreign materials. Carefully remove any of these
materials from the wheels.
• When the car slows down or the control range decreases, insert
new batteries.
• Please do not allow the car to fall off a high ledge, as a fall
might damage it.
• Never disassemble your car or the transmitter.
• Do not store the car either near a source of heat or in direct
sunlight for extended periods.
• You may experience interference from CB radios which use
the same frequency. If this occurs, move to a new location or
wait until the interference is over. Also, two or more R/C cars
using the same frequency cannot operate in the same area
since their signal will interfere with each other.
• The transmitter range will depend on surroundings, buildings
and large metal objects. You will obtain the best results when
you operate the car in an open area.
• When not in use, set the car and transmitter Power Switches to
“OFF.” If you do not intend to use the car for a long time,
remove the batteries, as weak or dead batteries can leak
damaging chemicals.
