1. TRANSMITTER■ Loading batteries:Loading batteries:Loading batteries:Loading batteries:Loading batteries:You may us either NiCad batteries or Alkaline “AA” size batteries (NiCad recommended)✷ Push the bottom battery cover in the direction of the arrow then lift up the cover.✷ Load 8 “AA” batteries (be sure the polarity is correct).✷ Reinstall battery case with installed “AA” batteries with connections to the top left.

✷ NiCads should be charge before use.

With new alkaline or freshly charged NiCads the GrGrGrGrGreeneeneeneeneen light should be lit. With use the GrGrGrGrGreeneeneeneeneenlight will turn to AmberAmberAmberAmberAmber. If the RedRedRedRedRed light begins to flash, operation should be stopped and thebatteries should be recharged or replaced immediately.

■ Optional NiCad Battery Installation (part # 58207).

1. Plug the white battery plug into the receptacle in the bottom of the pistol grip handle.(Refer to Illustration)

2. Push the pack up into the battery bay.3. Replace the cover.4. Check the power level.5. Charge if needed. (Refer to illustration below)

■ ■ ■ ■ ■ Recharging NiCad BatteriesThe LYNX is equipped with an external charging jack so there is no need to remove thebattery pack from the transmitter. The Hitec CG-22 or 25A are made to charge these typesof batteries overnight or the approximately 12-15 hours. Please refer to the followingdiagram, check to see that the charge light lights up after the connection is complete.

■ ■ ■ ■ ■ Transmitter AntennaYou must attach the transmitter antenna by screwing it into the hole located at the top left/center of the transmitter. You may take the antenna out to store it. This storage area islocated on the backside of the transmitter. Always attach your antenna before use or youwill experience sever shortage of operating range that could result in damage to your vehicleand or injuries to yourself and others.

■ ■ ■ ■ ■ Changing X-talsChanging the x-tal to void conflicts with other vehicles is possible where permitted. (You mustcheck your local rules before doing so. For example, in the US, the FCC prohibits the changingof transmitter x-tals on 72 and 75MHz). If you are eligible to change the x-tals, both thetransmitter and receiver x-tals must be changed together. You must change within the sameband, i.e. 75MHz to 75MHz, 27MHz to 27MHz, different bands can not be intermixed if yourradio is on 75MHz then 27MHz x-tals cannot be used. Use only Hitec x-tals when changingfrequencies.

2. Installation of Receiver and Servos

■ ■ ■ ■ ■ Using separate power source for the receiverWhen using a separate power pack for the receiver instead of sharing the main power source,please refer to the following diagram. After installation, turn on the power to the transmitterfirst then turn the receiver on. (Always turn the transmitter ON first and OFF last.) This willprevent the receiver from picking up stray signals and going out of control. Now, move thecontrols to see if the servos are moving properly. If not, Check your wiring, battery charge or x-tals if the servos do not move at all.

(Please verify whether your ESC has a built in B.E.C. circuit.) Plugthe receiver connector from the speed control into the “THROTTLE” or #2 channel on thereceiver, and the steering servo into the “STEERING” or #1 channel on the receiver. Nowyou can connect the main power to the speed control and when the power switch is turnedon the speed control will regulate the power that the receivers can use.

✷ After the installing of the servo and receiver into your model, turn the transmitterpower “ON” and fully extend the antenna, now turn on the receiver. (It is advisable toremove the pinion gear from your car so that the wheels do not engage for this test).

✷ Check to see if either servos or speed control are working properly. If not check theconnections and make sure the main battery pack is charged.

✷ Check to see if the servos are moving in the correct direction. If not, change theposition of the servo-reversing switch located on the top of the transmitter to achievethe correct direction.

✷ If everything checks out then turn the receiver “OFF” first then the transmitter. (Alwaysremember; never have the receiver “ON” without the transmitter also being “ON”).

Selectable via the screw adjustment on the face of the transmitter, this canbe used in situations where your dual rates are set so the car does not “Oversteer” on themajority of the track but is set low to get around the hairpin. By pushing the “SRO” switchas you approach the hairpin turn, you will get the preprogram amount of throw immediatelyand be able to get around the turn faster. If you are stuck against the hose/board/wall/etc.and don’t have enough steering throw to get you out, the “SRO” button on the LYNX canget you out when other radios can’t. Experiment with this feature you will find it verybeneficial.

The servohorn or arm should be a 90 degrees and the wheels should be straight. If not then make thehorn or arm 90 degrees by removing it and replacing it correctly. If the arm is at 90degrees and the wheels are not straight, adjust the linkage to compensate. Once you havethese two settings correct, use the steering trim for fine-tuning. Note: Always trim yourcar before you run or race. This is a common mistake made by beginners. If you have tosteer your car to go straight, you are fighting a loosing battle. Make sure it tracks straightbefore you run it and driving will become much easier.

Thisadjustment is critical for racers fine-tuning their cars handling “On the Fly”. The rate canbe selected from 40% - 100%. If your car is loose or “Oversteering”, dial the adjustmentback. If your car is pushing or “Understeering”, then dial the adjustment forward. Thisadjustment is a must for setting up your car to perform at its best. Adjust the servo so at100% of travel (the dial will be all the way forward), the servo does not bind. If the servobinds, adjust the linkage to compensate.

Adjust the servo link rod so that point “B” will arrive at the neutral position. When thetrigger is pulled to the maximum point, “C” should be as illustrated and at point “A” whenthe trigger is pushed to the limit. Check to see if the vehicle moves forward when thetrigger is pulled. If the vehicle moves backwards the “Throttle” reversing switch will needto be switched. If the model moves forward or reverse at the neutral position, use thethrottle servo trim to fine tune. If the servo moves the speed control farther than is neededuse the “EPA” adjustments to limit the travel to the proper distance.

✷ Adjust the full power position of the ESC (forward only) when the trigger is pulledapproximately 90% of the way. If the vehicle does not move forward when the triggeris pulled and does when the trigger is pushed, check the motor connection first. If thatis correct then switch the throttle reversing switch to the opposite direction.

✷ Adjusting the full power position of the ESC (reversible version) is the same as theforward only, except you must make sure you are adjusting the forward not the reverse.If the trigger is pulled and the full power adjustment does not affect the speed but doeswhen the trigger is pushed, the servo reversing switch for the throttle needs to be changedto the opposite direction. After this is determined, use the same 90% as discussedpreviously for forward. Reverse on most speed controls is not adjustable.
