Please pay attention to the change of surrounding environment when charging the battery,
otherwise leakage, smoke, explosion and even fire may occur.
Only the built-in lithium battery specially designed for the instrument can be used. Do not use
other types of batteries. Please use the charger specified by Grandway company for charging. If the
charging is not completed within the specified time, please stop charging immediately. Because the
electrolyte inside the battery is alkaline, if the battery leaks or breaks and comes into contact with the
electrolyte, it will damage clothes and skin. If electrolyte gets into the eyes, it may cause blindness. In
case of such an accident, please wash your eyes thoroughly with clean water immediately and see an
ophthalmologist immediately. In order to prevent electric shock explosion accident, do not put the
machine into fire or heat it, it will explode.
1.2 Electrical safety
Use the correct power supply
Before connecting the power line, please make sure that the power supply voltage is the rated
voltage of the charging adapter, and the maximum voltage should be less than the rated voltage that
the power line can withstand.
Use the correct power cord and charging adapter
Please use the attached power cord and charging adapter, do not use other power cord and
adapters.
1.3 Laser safety
Do not aim the laser emitter at human eyes, otherwise it may cause permanent and irreversible
damage.
Do not look directly at the laser, do not touch the light directly emitted by the laser, the light
reflected by the mirror, or the light incident through a specific eye shield. In addition, please avoid
direct exposure to laser, it will cause eye damage and blindness, it is best to use the cover to cover the
unused optical interface.
