• Be sure the transmitter is in PPM modulation mode. If necessary, refer to the instructions included with your radio system for details on how to program your
transmitter to PPM modulation. Note: The Spektrum module system will not operate in PCM modulation mode.
• Never power up the module unless the antenna is connected. Doing so can overload the module’s electronics causing damage to the module.
• Before operating, the receiver must be bound to the module (see page 16 for binding instructions). Binding is the process of teaching the receiver the transmitter’s
specific GUID (globally unique identifier) code. Binding also sets the failsafe positions. It’s also recommended that the system be rebound again after radio setup to
establish and confirm the desired failsafe positions.
• Before each flying session, it’s imperative that you do a range check (see page 24 for details) to confirm that the system is working properly.
• When using the Module system with the AR6100 and AR6110 park flyer receivers, it’s imperative that these receivers only be flown in parkflyer-type models. This
includes all types of small electric airplane and mini and micro helicopters. DO NOT fly the AR6100 or AR6110 receivers in large gas or glow aircraft as loss of
control at extended range due to signal blocking issues can occur.
• The Module system features DSM2 technology and is compatible with all DSM2 compatible receivers. The Module system is not compatible with the AR6000 DSM
first generation receiver.
• Converts most popular brands of module based radio systems to Spektrum’s DSM2 2.4GHz technology
• No more waiting for an open frequency
• Eliminates the possibility of interference from an unintentional turn-on
• Bulletproof interference rejection of all outside RF sources like cell phones, WiFi systems, other transmitters, etc.
• Impervious to model-generated RF interference (like noisy electric motors, metal-to-metal noise or ignition systems)
• Operates on the 2.4GHz ISM band allowing international use
• No maintenance or tuning ever required
• Failsafe system drives the throttle to preset position at loss of signal (see failsafe options on page 19)
• Legal at all AMA flying field and events
