Users Manual of DEVO-7 transmitter
Part one:General information
1.0 Foreword
DEVO-7 adopts 2.4 GHz Direct Sequence Spread Spectrum (DSSS) technology and
features automatic ID binding, automatic ID assignment, and also features fixed ID set
by you yourself. The usage of wireless copy function keeps you away from the trouble
in wire link-up. Three mode types of helicopter, airplane and glider are available to meet your requirements for different models. The 2.8”LCD display big size letter
which offers more convenient operation. USB update on-line ensures a transmitter in
hand not to be out of date and makes it full of vigour.
1.1 Important Statements
(1) The transmitter is suitable for experienced radio controlled helicopter modelers
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, usage or control as
soon as the transmitter is sold out.
(4) We consign our distributors to offer technical support and after sale service. Please contact the local distributors for problem solutions caused by usage ，
operation, maintenance, etc.
DEVO-7 Page 5 of 170
1.2 Satety Needing Attention
(1) Far away from obstacle and people
RC helicopter in flight is uncertain of flight speed and status，which potential risk exists in. when flying， please keep your RC helicopter far away from people，high buildings， high-tension line，etc，and avoid operating in rain，storms，thunder and lightening.
(2) Away from humidity environment
RC helicopter should be kept away from humidity and vapor because it is composed
of complicated precise electronic elements and mechanic parts.
(3) Proper operation
Please use original spare parts to upgrade，modify or maintain your equipment in
order to assure its safety. Please operate your equipment within the range of functions
permitted. It is forbidden to use out of the safety laws or regulations.
(4) Safety operation
Please operate your equipment according to your body status and flight skills. Fatigue，listlessness and mis-operation will increase the possibilities of accidental
hazard.
（5）Away from heat sources
The inside of the transmitter is composed of many precise electronic components and
mechanical parts. Keep it far away from heat sources and sunshine to avoid distortion，or even damage caused by high temperature.
1.3 Attention Before Flight
(1) Ensure the battery packs of both transmitter and receiver are fully charged
(saturated).
(2) Ensure both the throttle stick and the throttle trim of your transmitter stay at the
lowest positions before operation.
(3) Please strictly obey the order of turn-on and turn-off before operation. When
starting your flight， turn on your transmitter first， and connect the battery to the helicopter later. When turning off the helicopter， disconnect the battery first， and
turn off your transmitter later. An upset in the order of connection may cause your
helicopter out of control. Please form a correct habit of turn-on and turn-off.
DEVO-7 Page 6 of 170
(4) Ensure whether the directions and actions of the servos are correct when
executing commands of the transmitter. Using a broken servo will result in unforeseen
dangers.

If come to the following image, press R or L , turn ON to OFF, press EXT to exit.
11.0 Installation requirement for receiver
1) / It is important to correctly mount your radio system in your model. Below are
DEVO-7 Page 20 of 170
some advices on how to install your equipments.
2) Wrap the receiver with 10mm thick foam and fix it with a rubber band or magic
string on your helicopter or airplane. It helps protect the receiver.
3) It is necessary for you to use rubber grommets and copper sleeves to isolate the
vibration from the main body. The mounting screws cannot be over-tightened. Otherwise， the rubber grommets will be distorted and decrease the vibration
absorption effect.
4) When mounting the servos， make sure the servos’ bellcranks can move freely
over their whole travel range and ensure the control linkages don't touch or
impede the movement of the servos.
5) If installing various switches， please keep them far away from the engine tuned
pipe and high vibration sources. Ensure all the switches move freely over their
whole range.
6) Don’t make the receiver antennas wrapped or parallel.
12.0 Installation requirement for Battery pack
Open the battery cover of the transmitter and take out the battery box. Then put 8 cells
AA battery or the same size full charged 8 cells NIMH battery into the battery box.
Please check again to make sure the polarities are correct.
Warning: Do not put the polarities of batteries in the opposite directions.
