3Product safety and radio frequency exposure
Before using the Xiegu X6100, please read this extended
manual carefully. It contains important instructions for
the safe and proper use of the radio as well as operating
instructions for compliance with the limits for radio
frequency exposure in accordance with the applicable
national and international standards.
3.1 Instructions on using the radio
Please read the following quick guide as failure to follow these rules can be
dangerous or against the law.
1. Observe local and national regulations before using this radio, as improper
use may violate applicable laws.
2. Do not charge or replace the battery contained in the radio in a flammable or
explosive atmosphere.
3. Do not use a radio with a damaged antenna, as touching the damaged
antenna may result in injury.
4. Do not attempt to dismantle the radio; all servicing should be carried out by
qualified technicians. Opening the device will also invalidate any warranty
claims.
5. Do not place the radio in the airbag deployment area of vehicles equipped
with airbags.
6. Stay at least a few meters away from the antenna system connected to the
radio.
7. Ensure that the antenna system is adequately earthed and has appropriate
lightning protection.
8. Do not transmit for long periods of time as this may damage the radio or
cause it to become hot enough to cause injury.
9. Do not use the device during thunderstorms. Disconnect the device from the
power supply and the antenna beforehand.
10. Do not connect an AC power supply to the DC interface on the left side of the
transceiver. Doing so may cause interference or damage to the device.
11. Do not apply a voltage of more than 15 V DC to the DC interface on the left
side of the transceiver. Doing so may cause interference or damage to the
device.
12. Do not reverse the polarity of the power supply cable. Doing so may cause
interference or damage to the device.
13. Do not operate or touch the appliance with wet hands. Doing so may result
in electric shock or damage to the appliance.
14. If you notice smoke or a strange odor, immediately disconnect the power
supply, unplug the power supply cable and contact the supplier.
15. If the radio emits smoke or a burning smell, switch it off immediately,
disconnect it from the power supply and contact your dealer.
Radioddity Extended manual for Xiegu X6100 v1.0
V1.0 © Radioddity 2024 page 11/132
16. Do not use the device in areas, vehicles or airplanes where this is prohibited.
Do not use the device while driving or operating technical equipment.
17. Do not use the device at filling stations or in places where flammable gases
are present or in the vicinity of potentially explosive atmospheres.
18. To avoid electromagnetic interference, turn off the radio in places where signs
with similar instructions such as ‘Do not use wireless devices’or ‘Turn off cell
phones’are posted, such as in hospitals and healthcare facilities or in an
environment where people carry medical equipment.
19. Do not expose the device to rain, snow or other liquids. Otherwise, the device
may be damaged.
20. When using headphones, make sure that the volume is not set too high.
21. Do not disassemble or modify the device.
22. Do not place the device near a heat source or in direct sunlight.
23. Do not place the device in a dusty or damp place.
24. Do not place the device in an unfavorable location.
Important notes:
•Make sure that you have the appropriate operating licenses before transmitting on
the amateur radio frequency band.
•Make sure that the connected antenna is suitable for transmitting on the set
frequency and with the set output power before you actually transmit.
•The device can become very hot during continuous and long-term transmissions
(e.g., FT8 operation). Please extend the transmission pauses accordingly and ensure
sufficient dissipation of the heat generated.
•Please set up the device in a safe and reliable place and keep it away from children
or unauthorized persons.
3.2 Electromagnetic interference
When using wireless LAN or Bluetooth devices, please note that other wireless
devices such as wireless mice, wireless keyboards and wireless routers operating
in the same frequency band may interfere with each other, resulting in an
unstable or interrupted connection of the device. In such a case, please stay away
from other devices or stop using these devices.

3.3 Notes on the battery included
This device contains a lithium-ion battery. Improper use may result in hazards
such as smoke, fire or battery breakage.
•The battery pack is installed in the rear panel of the device. Do not knock
against the rear panel of the appliance.
•Do not place the device in a location where the temperature may exceed 60
°C; otherwise, the housing may break or catch fire.
•Do not place the back of the device near heat sources such as ovens or direct
sunlight.
•Do not solder, disassemble or modify any of the included components
yourself. This can lead to failure of the device protection and damage to the
components, which in turn can lead to fire hazards and other dangers.
•In the event of obvious deformation, leakage or noticeable odor at the
installation site of the battery pack, the device must not be used any further
and the dealer must be contacted immediately for assistance.
•Do not use the device outside its temperature range; otherwise, the service
life of the device and the battery pack may be shortened or damaged.
•Do not leave the battery pack in a fully charged or fully discharged state for a
long period of time. Otherwise, the battery life will be shortened. Please keep
the charge level of the battery pack at 40%~50% if the device is left unused
for a long time, and then store it properly.
•The service life of the built-in battery pack is usually about 3~4 years. Please
replace the battery pack when its service life reaches this period. Even if the
battery pack is still working, its performance will be significantly reduced and
the operating time will be greatly shortened. The battery pack can generally
be charged and discharged 300 to 500 times. This depends on the specific
conditions of use.
•Do not charge the device with other, non-compliant chargers.
•Pay attention to the condition of the device when charging. Interrupt the
charging process immediately if you notice an anomaly.
•Do not charge the device in vehicles in direct sunlight.

2. Do not expose the device to direct sunlight or an environment where
electronic circuits may corrode.
3. Do not carry the device by the hand-held microphone or any connection
cables connected to the radio.
4. Opening or modifying the device will void any warranty.
5. The use of firmware not intended by the manufacturer for use with the device

products on the surface of the device or the printed labels. Chemicals can
damage the housing and display and remove the print. Before switching on
the radio, please make sure that the device is completely dry.
