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.
