Introduction
Thank you for purchasing the Lynx 4S Radio by Hitec!
As Hitec’s latest contribution in outstanding surface radio technology, the four-channel Lynx 4S is equipped
with lightning fast 4ms response, 4096 resolution, and Hitec’s unique bi-directional, AFHSS (Advanced Frequency Hopping Spread Spectrum) function for use with all popular R/C-operated models. Feature-packed with
an easy-to-use interface, the Lynx 4S design promises a more enjoyable and safer R/C experience than ever
before.
Prior to using your Lynx 4S 2.4GHz system, it is highly recommended that you read this manual carefully and in
full to ensure operation of the unit as intended. It’s also a good idea to keep these instructions with your Lynx
4S for easy reference at all times.
Please note that Hitec reserves the right to make production changes during the life of our product lines
which may impact the information in this manual.
For the most up-to-date information on this and any other Hitec product, visit our web site at www hitecrcd.com.
Safety Precaution
Flying models can be dangerous if proper safety precautions are not followed as described. Here are a few critical safety suggestions to keep you and others safe.
Do not operate the Lynx 4S during inclement weather.
Do not operate under conditions of poor visibility.
Do not operate your model in close proximity to others wherever their presence could result in personal
injury or property damage.
Do not operate R/C boats where passenger boats are present or where swimmers, bathers, or others participating in water activity may be in danger.
Please note that Radio Control Systems are susceptible to interference when high tension power lines, power
transmission towers, or power transmission sites are near.
Minors under 19 years of age are encouraged to operate their model under adult supervision.
We strongly recommend that anyone new to R/C solicit guidance from seasoned users or their local R/C shop.
Do not store your R/C system in places exposed to extreme heat (over 40°) or cold (below 10°), or where it
can be compromised by direct sunlight, dust, or jarring.
Prior to activating your model, always check your Lynx 4S for a normal response. Double check that your settings are as desired and that your radio is functioning as it should.
P4
MANUAL: SECTION 1
Safety Precaution (cont.)
Always check the transmitter’s throttle trigger to be sure it rests in a neutral position before powering “ON”
your system. Make sure your model’s engine is not running when powering down.
Always turn the transmitter power switch on rst before turning on either the receiver or speed control. Reverse the order when powering down: be sure to turn off the receiver and speed control rst, then power off
your transmitter.
Always set up the fail safe function. The fail safe function is a safety feature that minimizes damage by moving
the servos to a preset position when reception fails.
When the Lynx 4S is not being used, always remove or disconnect the battery to prevent personal injury or
property damage.
Do not drop the battery or subject it to jarring vibrations or extreme temperatures.
Do not leave the radio system or models within the reach of small children.
Leakage from the battery may potentially result in skin burn, loss of sight, and other injures. If exposed, thoroughly rinse the affected area and contact your doctor for proper treatment response.
Use approved transmitters, receivers, servos, ESCs (electronic speed controls), Ni-MH/Ni-CD batteries and
other optional accessories ONLY. Hitec is not responsible for issues that arise from the use or misuse of
equipment not specied in this instruction manual or our catalog.
Always exercise proper care in the use and storage of your Hitec product. Exposure to vibration, dust, or extreme temperatures may affect its functionality and your safety.

Changing the Position of the Steering Wheel
Installing the Extension Adapter (included) gives you the option of changing the location of the steering wheel.
The adapter improves comfort control for the Lynx 4S by allowing the steering wheel unit and throttle trigger
to be positioned at the same level.
Disassembling the Steering Wheel Unit:
You will need a Phillips screwdriver to complete the following procedure. Do not force the bolts together or apart if
you encounter resistance as you can damage the unit. Work with the bolts until they slide easily into position.
1. Lift the groove under the steering wheel cover to remove it.
2. Loosen the 2.6 x 12mm screw bolt afxed to the steering wheel.
3. Pull the steering wheel adapter apart by hand to separate.
