Problem
Possible Cause
Solution
• The system will not
connect
• Your transmitter and receiver are too close
together. They should be 1 to 4 feet apart.
• You are around metal objects.
• Your transmitter was accidentally put into
bind mode and is not bound to your receiver
anymore.
• Move transmitter 1 to 4 feet from receiver.
• Move to an area with less metal.
• Rebind your transmitter and receiver.
• The receiver goes into
failsafe mode a short
distance away from the
transmitter
• Check the receiver antenna to be sure it is not
cut or damaged.
• Replace SR3100 antenna (SPM9005) or contact
Horizon Product Support
• Make sure your antenna is in an antenna tube
and up in the air as high as possible
• Receiver quits responding
during operation
• Inadequate battery voltage
• Loose or damaged wires or connections
between battery and receiver
• Charge batteries. Spektrum receivers require
at least 3.5V to operate. An inadequate power
supply can allow voltage to momentarily drop
below 3.5V and cause the receiver to brown out
and reconnect.
• Check the wires and connection between battery
and receiver. Repair or replace wires and/or
connectors
general noTes
As the user of this product, you are solely responsible
for operating it in a manner that does not endanger
yourself and others or result in damage to the product
or the property of others.
Carefully follow the directions and warnings for
this and any optional support equipment (chargers,
rechargeable battery packs, etc.) that you use.
Safety Points to Obey for Modelers
• Ensure your batteries (both transmitter and receiver)
have been properly charged for your model.
• Keep track of the time the system is turned on so
you will know how long you can safely operate the
transmitter.
• Check all servos and their connections prior to
each run.
• Do not operate your model near spectators, parking
areas or any other area that could result in injury to
people or damage of property.
• Do not operate your model during adverse weather
conditions. Poor visibility can cause disorientation and
loss of control of your model.
• Do not point the transmitter antenna directly toward the
model. The radiation pattern from the tip of the antenna
is inherently low.
• Do not take chances. If at any time during the operation
of your model you observe any erratic or abnormal
operation, immediately stop operation of your model
until the cause of the problem has been ascertained
and corrected. Safety can never be taken lightly.
