EXCESSIVE MOISTURE.
PLEASE WATER PROOF THE RECEIVER AND SERVOS

Troubleshooting Guide
If your radio system does not operate properly, please
check the following items:
1. Make sure the batteries are properly installed and
check the polarity (+ and -) again.
2. Check that both the transmitter and receiver power
switches are in the ON position.
3. Check the LED Power Indicators and make certain
that all three are on. If not, replace the batteries.
4. Make sure all the receiver and servo connections
are tight.
5. Make sure that the proper frequency crystals are
installed in the transmitter and receiver.
1. Press down on the battery cover and slide
in the direction of the arrow to remove.
2. Install 8 pieces “AA” size alkaline batteries as
indicated on the battery tray. Make sure to match
the polarity (+ and -) as shown in the battery
compartment or the transmitter will not function.
3. Install the battery cover in place and slide to close.
WARNING: Improper installation of transmitter batteries
can cause serious damage to your system.
Your Blazer or Blazer Sport R/C system is equipped
with a BEC receiver to eliminate the need for a
separate battery receiver pack, but you can use a
separate power supply if desired for your particular
model. The following diagram shows a typical
connection for the servos and receiver.
Note that the receiver antenna should be located at
least 2” (50 mm) away from any servo leads and
switches. In electric cars, we recommend that it be
at least 4” (100mm) from the electric motor.
Extend the receiver antenna to the full length. Failure
to do so will cause loss of control. Do not cut or bend the
receiver antenna.
Be careful to avoid any metal parts coming in contact
with the servo connectors as this will affect the
performance. Insulate the connectors with tape or use tie
wraps to avoid contact with metal car chassis.
Please follow the model manufactures recommendations
for the correct installation of your radio system in your
car or boat.
