3. Intended use
The "GT2+1 EVO" 3-channel remote control is designed exclusively for private use in the model building area with the
associated operating times. This system is not suitable for industrial use, such as controlling machines or equipment.
Any use other than the one described above damages the product. Moreover, this involves dangers such as short-cir-
cuiting, re, electric shock, etc. Do not alter or modify the product. Please observe the safety instructions at all times!
Always follow the safety information in these operating instructions. It contains important information on
how to use the product safely.
You are solely responsible for the safe operation of the model and the remote control!
4. Product description
With the "GT2+1 EVO" 3-channel remote control, you have a wireless remote control system that is ideal for model
vehicles or model ships. The driving and steering functions can be operated remotely independent of each other via
the two proportional control channels 1 and 2. In addition, the remote control has a third control channel that can be
used for switching tasks or additional control functions.
The ergonomically shaped casing ts comfortably in your hand and thus allows convenient operation of the transmitter
and secure control of the model.
For operation, the transmitter requires four AA/Mignon batteries. Unless a speed controller with a BEC circuit is used,
the receiver requires either four AA/Mignon batteries or four AA/Mignon rechargeable batteries with the corresponding
battery holder. Alternatively, a 4- or 5-cell NiMH receiver battery pack can be used.

6. Safety instructions
Damage caused due to failure to observe these instructions will void the warranty. We shall not be
liable for any consequential damage.
We shall not be liable for damage to property or personal injury caused by incorrect handling or
failure to observe the safety information! Such cases will void the warranty/guarantee.
Normal wear and tear in operation and damages due to accidents (like the receiver antenna tearing off, or
the receiver case breaking etc.) are excluded from the warranty.
Dear customer, these safety instructions serve to protect not only the product, but also your own safety and
that of other persons. Read this section very carefully before using the product.
a) General information
• The unauthorised conversion and/or modication of the product is prohibited for safety and approval
reasons.
• This product is not a toy and is not suitable for children under 14 years of age.
• The product must not get damp or wet.
• Operation of a model (such as a car model) may result in property damage and/or personal injury. There-
fore, make sure that you are adequately insured for the operation of the model by liability insurance. If
you already have purchased such a policy, contact your provider to check that the remote controlled
model is covered by the policy.
• Do not connect the drive motor to electric models before the receiver system has been completely
installed. This stops the drive motor from starting before you are ready.
• Check the functional safety of your model and the remote control system before each use. Inspect the
parts for any signs of damage, such as broken connectors or damaged cables. All moving parts on the
model must operate smoothly, but must not have any play in the storage.
• Operation and handling of RC models must be learned! If you have never used such a model, start very
carefully and get used to the model's reactions to the remote control commands rst. Be patient!
• Do not leave packaging material carelessly lying around, because it could become a dangerous toy for
children.
• If you have any questions that are not answered by these operating instructions, contact us (see
chapter 1 for contact information) or an experienced technician.

b) Operation
• If you do not have sufcient knowledge of how to operate remote-controlled models, contact an experienced model user or a model club.
• When putting the device into operation always turn on the transmitter rst. Only then turn on the voltage/
power supply for the receiver in the model. Otherwise, the model car can have unpredictable reactions.
• Before using the model, check whether it responds properly to the remote control commands.
• For a car model, a surface should be selected that allows the wheels to rotate freely. Do not hold the car
model by the wheels.
• For a ship model, make sure that the ship’s propeller can rotate freely. Always keep clear of the rotating
area of the ship’s propeller. There is a risk of injury!
• Ensure that people and objects are kept at a safe distance from engines and any other rotating parts.
• Improper use can cause serious injury and damage to property! Always keep the model in your line of
sight and never operate it at night.
• Do not use the model if your responsiveness is impaired. Fatigue, alcohol and certain medications can
affect your responsiveness.
• Never use the model in an area that may endanger other people, animals or objects. Only operate it on
private sites or places which are specically designated for remote-controlled models.
• In the event of a malfunction, discontinue use immediately and establish the cause of the problem before
using the model again.
• Do not use the remote control during thunderstorms, under high-voltage power lines or in the proximity
of radio masts.
• Always leave the remote control (transmitter) turned on when the model is in use. To turn off the model,
always switch off the motor rst, and then switch off the receiver system. Only then can the remote
control transmitter be turned off.
• Protect your model and the remote control system from dampness and dirt.
• Do not expose the remote control to direct sunlight or excessive heat for prolonged periods.
• The weaker the batteries, the lower the range of the remote control. If the receiver batteries or the receiv-
er rechargeable batteries become weak, the model will no longer respond correctly to the remote control.
If this is the case, stop operation immediately. Then replace the batteries with new ones or recharge the
receiver rechargeable battery.
• Do not take any risks when using the product! Always use the model responsibly, otherwise you may
endanger yourself and your surroundings.

7. Battery information
• Keep batteries out of the reach of children.
• Do not leave batteries lying around, as they present a choking hazard for children and pets. Seek im-
mediate medical advice if a battery is swallowed.
• Batteries/rechargeable batteries must never be short-circuited, taken apart or thrown into re. This may
cause an explosion!
• When handling leaking or damaged batteries, always use suitable protective gloves to avoid burning
your skin.
• Do not attempt to recharge disposable, non-rechargeable batteries. This may cause a re or explosion!
Only recharge compatible rechargeable batteries and ensure that you use a suitable battery charger.
• Please observe correct polarity (plus/+ and minus/-) when inserting the batteries/rechargeable batteries.
• If the device is not used for a longer period of time (e.g. storage), remove the batteries/rechargeable
batteries from the remote control and from the model to avoid damage from leaking batteries/rechargeable batteries.
• Rechargeable batteries should be charged at least once every three months to prevent damage due to
deep discharge.
• Always replace the entire set of batteries or rechargeable batteries. Do not mix full batteries with half-full
ones. Always use batteries of the same type and from the same manufacturer.
• Never mix non-rechargeable batteries with rechargeable batteries.
• For reasons of operational safety, only use disposable batteries for the remote control transmitter. Do
not use rechargeable batteries.
8. Receiver power supply
The receiver can either be operated directly via the BEC circuit of the speed controller or via a separate receiver power
supply. The latter can be realised with four AA/Mignon rechargeable batteries or four batteries. Alternatively, a 4- or
5-cell NiMH receiver battery pack can be used.
If you use rechargeable batteries to power the receiver, they will generally be empty upon delivery and will
need to be recharged.
Before the rechargeable battery delivers its maximum power, several complete discharge and charge cy-
If you use several rechargeable batteries, purchasing a high-quality charger may be worthwhile. They
cles are necessary.
normally charge rechargeable batteries quickly.

9. Remote control buttons
The illustrations in this manual show the GT2 EVO remote control, which is identical to the GT2+1 EVO
except for the switching function. This may cause labels or markings on your remote control to be different than depicted in this manual. However, the function notes described in the text refer exclusively to the
GT2+1 EVO remote control.
