Thank you for choosing RadioLink RC system, if you are the first time to use
this type of products, please read this statement carefully and strictly in accordance
with the requirements of operation. You could refer to the Manual if you meet any
problems during the operation . Please well keep the manual after use because you
might have to use it again next time.
If you found any problems during the operation process, please refer to the
manual. If the problem still exists, you could contact our dealers to find out the way to
solve it. And you could also log on our website for service:
Http://www.radiolink.com.cn
Important Safety Notice：
The following two symbols will appear in this manual（please pay attention to
the paragraph with this two symbols labeled）：
Prohibition Testing and confirmation
Do not use in bad weather such as rainy or thundering to assure the safety of
you and others.
Forbid to use this product in the crowd and the place against national law!
You need to turn the throttle channel(ch3) and inch switch to the lowest
before you use. Then switch on the transmitter, finally connect the receiver.
Before using, please make sure the movements of servo are corresponding
with the direction of joystick. If inconsistent, please adjust them before using.
Safety guides
Introduction and Service

3
The sequence to shut down is that turn off the receiver power first, and then
shut down the transmitter. If the above operations are reverse, it might lead to
uncontrolled situation and cause accidents
The transmitter needs to be powered by 4 AA alkaline 5# batteries or Ni-MH
batteries. Please check the voltage of batteries before using, as it might lead to
uncontrolled situation and accidents when the voltage is lacked. So you must change
the battery or recharge them in time.
Recharge steps：
A. Install the batteries to transmitter with correct directions, and cover it.
B. Connect the charger to the main connector.
C. Connect the charger to the transmitter charging port.
D. Cut off the power supply immediately while recharging completed.
Warning: Don’t try to charge to one-off dry batteries, avoiding a fire, explosion or
other severe consequence.
If you are using a nickel-cadmium, nickel-metal hydride batteries for recharging,
please use our company dedicated charger(optional accessory). If the electrical
current is too large and it might lead to overheated and cause a burning accident.
Please cut off the power supply immediately after recharging. Please take out the
batteries from the transmitter when you are not using it within a period, because the
battery might damage the battery connection metal flake, thus cause bad connection.
Above safety notices must be complied strictly, our company will not be
responsible for any damage caused by the behaviors forbidden in above notices.

Throttle servo delay
Sudden trigger operation on a slippery road only causes the wheels to spin and
the ve-hicle cannot accelerate smoothly. Setting the throttle speed function reduces
wasteful battery consumption while at the same time permitting smooth, enjoyable
operation.
Operation
Throttle servo (amp) operation is delayed so that the drive wheels will not spin even if
the trottle trigger is operated more than necessary. This delay function is not
performed when the trottle trigger is returned and at brake operation.
OFF,Speed1 or speed 2 can be selected.

Pulse brake
When the brakes are applied while cornering with a 4 Wheel Drive or other type of
vehicle, understeer may occur. The generation of understeer can be eliminated and
corners can be smoothly cleared by using this function.
Operation
- When the brakes are applied, the throttle servo will pulse intermittently. This will
have the same effect as pumping the brakes in a full size car.
- The brake return amount, pulse cycle, and brake duty can be adjusted.
- The region over which the ABS is effective can be set ac-cording to the steering
operation. (Mixing function)
