GENERAL NOTES |
PILOT SAFETY |
•Models are hazardous when operated and maintained incorrectly.
•Always install and operate a radio control system correctly.
•Always pilot a model so the model is kept under control in all conditions.
•Please seek help from an experienced pilot or your local hobby store.
•Contact local or regional modeling organizations for guidance and instructions about flying in your area.
•When working with a model, always power on the transmitter first and power off the transmitter last.
•After a model is bound to a transmitter and the model is set up in the transmitter, always bind the model to the transmitter again to establish failsafe settings.
•Always make sure batteries are fully charged before flying.
•Time flights so you can fly safely within the time allotted by your battery.
•Do a range check of the transmitter and the model before flying the model.
•Make sure control surfaces correctly respond to transmitter controls before flying.
•Do NOT fly a model near spectators, parking areas or any other area that could result in injury to people or damage to property.
•Do NOT fly during adverse weather conditions. Poor visibility can cause pilot disorientation and loss of control of a model. Wind, moisture and ice can cause loss of control and damage to a model.
•Do NOT point transmitter antenna directly at a model. The signal coming from the tip of the antenna is weak by comparison to the signal coming from other parts of the antenna.
•When a flying model does not respond correctly to controls, land the model and correct the cause of the problem.

QUICK START GUIDE
1. Install Main Receiver
Cover the main receiver in protective foam and attach the receiver in your gas or glow aircraft using rubber bands or hook and loop straps. In electric airplanes or helicopters, use doublesided foam tape to attach the main receiver to the model.
2. Install Remote Receiver
Install the remote receiver in the model using double-sided tape. Make sure the remote receiver antennas are more than 2 inches from the main receiver antennas. Always install remote antennas perpendicular to the main receiver’s antennas. Connect the main and remote receivers using the included 6-inch remote receiver lead.
3.Connect Servos to the Main Receiver
4.Install the Telemetry Module
Install the telemetry module in the aircraft using double-sided tape. Connect the telemetry module to the receiver’s Data Port. Receiver voltage and Flight Log data displays on your telemetry screen. If you want an external voltage (main flight pack voltage) to show on the telemetry screen, connect the voltage telemetry sensor in the telemetry module. Connect voltage telemetry wires to the input lead on the aircraft’s ESC using solder, with the polarity red=positive and black=negative.
5. Charging Radio Batteries
First, connect the included power supply to the charging port on the side of the transmitter and place the transmitter on a nonflammable surface. Second, connect the AC adapter to a power outlet using the appropriate outlet clip. Charge the included NiMH battery for 10-12 hours.
CAUTION: Do not overcharge batteries. Charging times greater than 12 hours may damage the battery and transmitter.
6.Bind the Receiver and Telemetry Module
A.Insert the bind plug in the receiver’s BIND/DATA port. In systems using a separate battery pack and 3-wire switch, insert the bind plug to the charge jack.
B.Power on the receiver. The LEDs on the receivers will flash.
C.Move transmitter sticks and switches to the desired failsafe positions (low throttle and neutral control positions).
D.Push in the Trainer/Bind button on the transmitter while powering on the transmitter. Once the transmitter has entered bind mode you can release the Bind button.
E.The LED on the receiver will show solid amber and the system will connect after several seconds.
F.Remove the bind plug.
Typical Electric - Receiver uses the ESC for power. Typical Glow/Gas - Uses receiver battery pack and 3-wire switch.
7. Charge and Test Receiver Batteries
Loss of power to the receiver and servos is the leading cause of failure. When using a receiver battery pack, make sure the pack is properly charged and check the voltage under a 1A or 2A load. Do not fly if the voltage is below 4.8V for a 4-cell pack while loaded. If the voltage falls below the receiver’s operating threshold (3.5 volts) at any time, an interruption in the link may occur.
8. Programming the Transmitter
Power on the transmitter, then power on the receiver. Make sure the model responds to the transmitter controls as desired. Use Servo Setup in the transmitter to reverse channels or adjust travel as needed. Program other functions as needed to safely control your model. Refer to additional sections of the manual for more information about programming your transmitter.
9. Re-Bind the System
Once the transmitter is programmed for your model, re-bind the system to set the failsafe position. If your model uses retracts, re-bind the system with retracts in the down position. If the signal is lost, the throttle servo will go to the preset position chosen during binding (normally low-throttle).
10. Range Check
A.With the system powered and the model restrained from flyaway, stand 30 paces (approximately 90 feet/30 meters) away from the model.
B.Face the model and hold the transmitter in your normal flying position. Go to the transmitter’s Range Test screen and press the Trainer button on the top of the transmitter. This causes reduced power output from the transmitter.
C.Operate transmitter controls to make sure you have total control of the model while holding down the trainer button.
D.If control issues exist, refer to the Troubleshooting Guide. If you continue to experience control issues, contact the appropriate Horizon Hobby Product Support office or go to
horizonhobby.com to find a local Spektrum distributor in your country of service.

Charging Your Transmitter
The DX7s includes a rechargeable NiMH battery pack. The DX7s has a built-in multi-chemistry charger designed to charge 4-cell NiMH and 2-cell LiPo batteries at a charge rate of 200mAh.
The charge port on the right side of the transmitter is not polarity-dependent.
CAUTION: Never connect a peak detection charger or fast charger to your DX7s. These devices can damage the internal charge circuit. Use only the included 12V DC source.
Charge in a safe place NOT affected by the usual heat that comes from a charger and batteries during charging.
1.Power off your transmitter.
2.Connect the power supply’s connector to the transmitter’s charge port.
3.Connect the included 12-volt power supply to a power outlet using the appropriate outlet clip.
4.The blue LED on the front of the transmitter will illuminate during charging.
5.The blue LED will remain lit when charging the included NiMH battery. When charging the optional LiPo battery the blue LED will go off when charging is complete.
6.Disconnect the transmitter from the power supply when charging is complete.
7.Disconnect the power supply from a power outlet when the power supply is not in use.
For first use, charge the included NiMH battery pack for 10 to 12 hours until fully charged. Use the included 12V power supply. If you purchase the optional LiPo battery pack (SPMB4000LPTX), the initial charge can take up to 30 hours.
CAUTION: Never leave a charging battery unattended.
Battery Alarm
The System Settings Screen allows you to change the battery type and low alarm settings.
•Always set the Battery Type to correspond with the chemistry of battery that is installed to enable the correct low voltage limit. When using a LiPo battery, you must connect the battery to the transmitter and then change the battery type in the programming. See Appendix for LiPo battery pack installation.
•An alarm will sound when the battery reaches the low voltage limit (4.3V for NiMH, 6.4V for LiPo).
CAUTION: Never change the low voltage limit for LiPo batteries from 6.4V. Doing so could over-discharge the battery and damage both battery and transmitter.

BINDING
You must bind the receiver to the transmitter before it will operate. Binding teaches the receiver the specific code of the transmitter. Once bound, the receiver only connects to the transmitter when the previously bound model memory is selected. You will need to rebind the receiver after the model is set in the transmitter to fully program the model’s failsafe positions. If another model memory is selected, the receiver will not connect. This feature is called ModelMatch™ and prevents flying a model using the wrong model memory.

USING THE TRANSMITTER
Antenna
The transmitter antenna bends and turns at the hinge (A) and only bends and turns to the front of the transmitter. The antenna cannot point to the back of the transmitter. Turn the antenna tip to point away from the model and ground. Signals transmit strongest from the antenna shaft, not the tip.
WARNING: Do not pick up the transmitter by the antenna. Do not alter or put weight on the antenna. Damage to antenna parts can decrease transmitter signal strength, which can result
in loss of model control, injury or property damage.
A
NOTICE: While DSMX allows you to use more than 40 transmit- 
ters simultaneously, when using DSM2 receivers, DSMX receiv- 
ers in DSM2 mode or transmitters in DSM2 mode, do not use 
more than 40 transmitters simultaneously.
