DEVO-8 Page no. Page 8 of 3631.1 ForewordDEVO-8 takes 2.4GHz Direct Sequence Spread Spectrum (DSSS)technology, features automatic ID binding, automatic ID assignment,and also features CUSTOMIZED fixed ID setup. The usage of wirelesscopy function keeps you away from the trouble in wire link-up. Threemode types of Helicopter, Airplane, and Glider are available to meetyour requirements for different models. Touch screen with wide area isused and it offers you convenient operation. USB Online updatetechnology ensures one transmitter in hand forever not to be out of dateand makes it full of vigor.1.2 Important statements1) The transmitter is suitable for experienced radio controlled aircraftmodelers beyond 14 years old.2) Flying the model aircraft in approved ground is a must.3) We are not responsible for any safety caused by operation, usageorcontrolassoonasthetransmitterissoldout.4) We consign our distributors to offer technical support and serviceafter sale. Please contact the local distributors for problemsolutions caused by usage, operation, maintenance, etc.
DEVO-8 Page no. Page 9 of 3631.3Safetyneedingattention1) Far away from obstacle and people.RC aircraft in flights is uncertai n of flight speed and status, whichpotential risk exists in when flying. Please keep your radio controlledaircraft far away from people, high buildings, high-tension line, etc, andavoid operating in rain, storms, thunder and lightening.2) Away from HUMID environmentRadio controlled aircraft should be kept away from humidity and vaporbecause it is composed of complicated precise electronic elements andMECHANICAL parts.3) Proper operationUse original spare parts to upgrade, modify or maintain your equipmentin order to assure its safety. Please operate your equipment within therange of functions permitted. It is forbidden to use out of the safety lawsor regulations.4) Safety operationOperate your equipment according to your body status and flight skills.Fatigue, listlessness and mis-operation will increase the possibilities ofaccidental hazard.5) Away from heat sourcesThe inside of the transmitter is composed of precise electronic
DEVO-8 Page no. Page 10 of 363components and mechanical parts. Keep it far away form heat sourcesand sunshine to avoid distortion, or even damage caused by hightemperature.6) Correct charging methodUse the assorted charger to charge the battery for your DEVO-8. Theusage of the charger should be within the range of rated voltage.
DEVO-8 Page no. Page 11 of 3631.4 Attention before flight1) Ensure the battery packs of both transmitter and receiver are fullysaturated.2) Ensure both the throttle stick and the throttle trim of your DEVO-8stay at the lowest positions before operation.3) Strictly obey the order of TURN-ON and TURN-OFF beforeoperation. When starting yo ur flight, turn on your DEVO-8 first, andconnect the battery to the aircraft last. When turning off the aircraft,disconnect the battery first, and turn off your DEVO-8 last. An upsetin the order may cause your aircraft out of control. Cultivate acorrect habit of turn-on and turn-off.4) Ensure whether the directions and actions of all the servos in yourRC aircraft are correct when executing commands of thetransmitter. Using broken servos will result in unforeseen dangers.

Below are some advices on how to install your equipments.1) Wrap the receiver with 10mm thick foam and soundly fix it with arubber or magic string on your aircraft model. It helps protect thereceiver from damage.2) It is necessary to use rubber grommets and copper sleeves toisolate the vibrations from the main body of aircraft model. Themounting screws cannot be over-tightened. Otherwise the rubbergrommets will be distorted and decrease the vibration absorptioneffect.3) When mounting the servos, make sure the servos’ bellcranks canmove freely over their whole travel range and ensure the controllinkages don’t touch or impede the movement of these servos.4) If installing various switches, keep them far away from the enginetuned pipe and high vibration sources. Ensure all the switchesmove freely over their whole travel range.5) Don’t make the receiver antennas wrapped or parallel.
