2USER SAFETY NOTES
Please read the following thoroughly for your own safety.
2.1 MEANING OF SYMBOLS
Contents marked with one of the following symbols in the manual require immediate
attention:
DANGER: This action can lead to death or serious injury to the user and/or others.
WARNING: This action might lead to death or serious injury to the user and/or
others. High risk of minor injury and/or damages to the product.
CAUTION: Although such operation has a low risk of serious injury to the user
and/or others, personal injuries and/or damage to the product can still occur.
NOTE: Steps, Tips or information.
2.2 FLIGHT SAFETY PRECAUTIONS
Please read the following section thoroughly for your own and/or the safety of others.
WARNING: Avoid flying when a low battery (red) icon is displayed in the top right
side of the screen. Do not rely on the low battery alarm function of the transmitter to tell
you when to land. Check the battery voltage of the transmitter and of the model battery
before each flight.
CAUTION: Maintain the transmitter properly to ensure correct operation. The data
of HORUS X10/X10S is saved on the IC and microSD during each power off operation.
The data will be lost if you run out of the battery while the transmitter is power on. Always
follow the prompts when turning off the radio via the power switch. We suggest a complete
inspection and if needed preventive maintenance service for the device at least annually
to ensure safe operation.
2.3 WHERE TO USE
We recommend you only use the transmitter at certified club sites for RC models. You can
enquire at a local dealer to find model clubs and fields near your location.

Page 10 15 December 2017
NOTE: Please pay close attention to the relevant regulations at the flying field,
position of the spectators, wind direction, obstacles inside the flying field, civil/military
aviation and the local wild life.
2.4 AT THE FLYING FIELD
WARNING: In order to remain in full control of the airplane, it is crucial to keep
the plane well within the limits of your eyesight. We do not recommend you to fly behind
large objects such as trees and buildings, which may cause a reduction of signal quality
received by the model’s receiver or even result in losing field of vision.
WARNING: Don't block the internal antenna located on the top the transmitter
screen, or the optional external antenna during use, this can significantly reduce the range
of the transmitted radio signal.
WARNING: Never use the transmitter unprotected in the rain. Rain and/or moisture
can enter the transmitter through the openings, which may cause erratic model behaviour
and even a runaway. If the use of the system during damp conditions is inevitable (during
competitions etc.), please be sure to cover the transmitter with a plastic bag or waterproof
cloth. Flight is prohibited when lightning occurs.
CAUTION: When it is necessary to put the transmitter down on the ground or flight
bench it is best and safest to place the transmitter on its back so that it rests as designed on
the handle. If circumstances require that you must place the transmitter standing upright
on the ground before taking off, make sure it cannot be accidently tipped over. If the
transmitter is flipped on its front side, the throttle stick may rotate and lead to a sudden
increase of the engines’ RPM. The tip-over might also do damage to the transmitter.
CAUTION: Never point the antenna directly at the model. If you encounter a low
signal warning or lose the connection during flight, check orientation and, if needed,
move the antenna to the recommended angle relative to the model.
2.5 SAFE USE AND HANDLING OF THE LI-ION
BATTERIES
The user should only use power adapters with/without FCX10 supplied by FrSky or those
that are approved by FrSky to charge the battery inside the HORUS X10/X10S transmitter.
It is important to be aware about the characteristics of the Li-ion battery. If you do not follow

Page 11 15 December 2017
the instructions, there is a high chance of inflicting terminal damage to the battery or
transmitter and can even lead to fire.
NOTE:There are two type of charge systems of Horus X10/X10S. To charge the
transmitter, plug the FrSky -provided power adapter cable connector into the transmitter
charging port and the power adapter into an AC electrical outlet.
Or connect the power adapter to FCX10 separately provided and then connect it to the
battery inside the radio through USB type C interface.
Important notes
DANGER: A small increase in temperature can be observed during normal charging
and discharging of a Li-ion battery. However, if the charger and/or battery is overheating,
the charge/discharge operation must be aborted immediately. If you suspect that the battery
has been damaged, we recommend to stop using it, and request you to discard it in an
appropriate way (please recycle).
WARNING: We do not recommend charging the transmitter with the power on. The
inbuilt charging circuit struggles to detect battery charge state due to fluctuating amperage
draw during use. When it is power on and keeps working, the LED will turn LIGHT BLUE.
WARNING: Never store batteries near an open flame and/or in other high
temperature conditions. We recommend to store them at normal temperature.
When charging the Li-ion batteries outside the transmitter, we advise to charge them in a
fire-proof container. Do not charge Li-ion batteries near flammable products and/or liquids.
It is good practice to install a fire alarm in close proximity of the charging area.
CAUTION: When Li-ION batteries indicate full charge in a cold environment, they
might not be fully charged. The low temperature has a negative effect on the total battery
capacity, this can result in an unreliable charge indication.
CAUTION: Li-ION batteries must be kept at a safe location and out of reach of young
children.
2.6 MICROSD HANDLING RECOMMENDATIONS
Please read the following thoroughly to insure correct operation.
WARNING: While transferring data onto the microSD card, do not turn off the
transmitter and/or extract the microSD card. Loss and/or corruption of the data can occur.

Page 12 15 December 2017
CAUTION: Keep microSD card clean, avoid direct sunlight, and stay from
moisture/water and/or any other type of potentially corrosive liquids.
WARNING: Never store the microSD card in an environment subjected to strong
electromagnetism.
NOTE: Always check the orientation of the microSD card before inserting to ensure
correct installation.
NOTE: Make sure the transmitter is turned off during removal and installation of the
microSD card, failing to do so can corrupt unsaved data.
CAUTION: The microSD card is a delicate component, never use excessive force
when inserting or removing the Micro SD card.
