MEANING OF SPECIAL MARKINGS
Pay special attention to safety where indicated by the following marks:
DANGER - Procedures which may lead to dangerous conditions and cause death/serious injury if not carried out properly.
WARNING - Procedures which may lead to a dangerous condition or cause death or serious injury to the user if not
carried out properly, or procedures where the probability of superficial injury or physical damage is high.
CAUTION - Procedures where the possibility of serious injury to the user is small, but there is a danger of injury, or
physical damage, if not carried out properly.
= Prohibited = Mandatory
Warning: Always keep electrical components away from small children.
To ensure the safety of yourself and others, please observe the following precautions:
Have regular maintenance performed. Although your radio does not have a battery to protect the model memories,
it still should have regular checkups for wear and tear. In the US, we recommend sending your system to the US
Futaba Service Center annually for a complete checkup and service.
CAUTION - Before Using Your System…
1. ALWAYS be sure the receiver, servo(s), ESC, crystal and connectors are fully connected prior to every operation.
Vibration, which occurs in all models, means regular inspections and maintenance are critical.
2. ALWAYS protect the receiver and NiCd battery from vibration by mounting them in thick double-sided tape or foam.
3. Aquatic users: ALWAYS protect all radio equipment from potential water damage by waterproofing. Send any
equipment subjected to water, fuel or other corrosive materials for testing prior to re-use.
4. NEVER cut or coil your receiver antenna or bundle it with any servo leads, battery wires, carbon fiber, metal or
other conductive materials.
5. ALWAYS keep the receiver antenna at least 1” away from motor/battery/ignition/other wiring carrying heavy current.
6. Electric Users: ALWAYS install the ESC heat sinks such that they can not come into contact with plastic,
aluminum, carbon fiber, or other conductive materials, or a short circuit may occur.
7. ALWAYS operate each servo full distance both ways and check for buzzing, binding, loose linkages, chatter, or
“stepping” in the movement (check for broken servo gears).
8. ALWAYS use the rubber grommets for servo installation, and ensure the servos do not come into direct contact
with the mount or anything that conducts electricity.
9. Electric Users: ALWAYS install capacitors on electric motors to suppress electrical noise.
10. ALWAYS inspect your model for metal-to-metal contact (including while engine/motor is running) which could
create electrical noise and result in erratic system operation.
11. ALWAYS range check your system.
12. NEVER leave the radio system or models within reach of small children. NiCd batteries can be very dangerous
when mishandled and can cause chemical damage.
13. NEVER store your radio equipment and models where they will be exposed to extreme heat or cold, direct
sunlight, high humidity, large quantities of dust, steam or condensation.
14. NEVER expose the plastic parts of your radio system to raw fuel, oil, exhaust, water.
15. NEVER touch the engine, motor, speed control, or any other part of the model which generates heat during
operation until the model is not operating, has been fully turned off and allowed to cool. These parts may be very
hot and can cause serious burns.
16. ALWAYS display a frequency flag when operating your model.
17. NEVER operate this R/C system when you are tired, not feeling well, or under the influence of alcohol or drugs.
18. NEVER operate near other radio control activity areas, on any ponds or lakes where rowboats or swimmers are
present, or near high tension power lines or communications broadcasting antennas.
