1.2.Safety Precaution
Electromagnetic Radiation
A two-way radio generates and radiates electromagnetic energy. Kirisun two-way radios strictly conform to
Chinese and international standards of electromagnetic radiation. To ensure ideal communication and
human safety, please keep the device vertical to the ground and keep the microphone 2 ~ 5cm away from
the mouth while using the radio.
Electromagnetic Interference
To avoid electromagnetic interference, turn off the radio in a place where you are so instructed, for example,
a hospital, a health center and an airport.
Explosive Gases
You’d better shut down the radio when you are in an area with explosive gas (for example, the lower deck
of a hull, a container or transport facility of fuel oil or chemicals) or with chemical or particles, dust or
metallic dusts in the air, or near a blast area or an electric blasting detonator. Replacing or recharging the
battery in potentially explosive atmospheres is prohibited.

You are suggested not to use the radio if the antenna is damaged. A damaged antenna may cause mild
burns when contacted with human skin.
