2) Connection to an improper power supply may cause burning, explosion or damage to printer.
3) Don’t put the battery into fire or water, don’t disassemble or modify the battery, don’t be
short circuit, otherwise may result in injury or even fire explosion.
4) If the printer would not be used for a long time, be sure to take off the battery, otherwise
the battery may leak liquid which is corrosive. If improper operation causes battery leak,
and the liquid is spattered on the skin or clothes, please wash it with water. if spattered
Into eyes, please rinse them with water thoroughly and soon see a doctor.
5) Please do not open the paper case cover while it is printing or just when printing is over,
do not touch the print head with hand or body, overheat may cause scald.
2. Operation Precautions
1) Water or other liquid should not spill into the printer, also the printer should not be exposed in rain or
else may cause printer damage.
2) Please do not open the paper case cover when it is printing, otherwise the printer may work improperly.
3) When printing with Bluetooth interface, the communication distance should be within 10 meters,
otherwise the printer doesn’t print or it will print rubbish codes.
4) Too high (50℃) or too low (-5℃) temperature and too high (80%) or too low (25%) relative humidity
both will affect the printing quality.
5) The thermal paper in poor quality or stored for too long time also may reduce the printing quality or
even damage the printer.
3. Storage Precautions
1) The printer should be placed in such an environment that the temperature is between -20℃ to 70℃,
and the relative humidity is within 5% to 95%.
2) If the printer will be stored for a long time, please be sure to take out the battery, otherwise may
damage the battery and printer.
3) Normal thermal paper can’t be kept too long, if you need to keep the receipt for a long period, please
choose long term effective thermal paper.
4) The thermal paper should be keep away from high temperature environment and point-blank sunshine.

4. Battery Safety Precautions
1) Be sure to carefully read the user manual before using this product.
2) Ignore the following instructions may cause battery overheating, burning, explosion, damages the
performance and reduce the product life.
① Do not allow water, sea water from entering or leaking into the battery inside. If the battery internal
safety device burn, when charging it, it may produce abnormal current, voltage, and chemical reaction to
cause the battery overheating, burning and explosion.
② Do not use or place the battery nearby the stove or other high temperature places. Excessive heat may
damage the resin shell or the insulation materials, thereby cause short-circuit inside the battery and result
the battery overheating, burning and explosion.
③ When charging, use a specified charger. Other conditions (high temperature, high pressure/high
current, using the modified battery charger, etc.) excluded here may result in over-charging the battery
and abnormal current or voltage, cause abnormal chemical reaction, and may cause the battery
overheating, burning or explosion.
④ Do not make the battery contact with the power outlet or car cigarette lighter socket. This may cause
high pressure and excessive current, and lead the battery overheating, burning or explosion.
⑤ Do not heat the battery or put the battery into fire. This may melt insulation material and damage
safety devices or safety equipment, then ignite electrolytic solution, and cause the battery overheating,
burning or explosion.
⑥ Do not use the battery with contrary (+) and (-) location. In the charging process, this will cause the
reverse charging and may cause abnormal chemical reaction. During use, may appear unpredictable
current exception, and cause the battery overheating, burning or explosion.
⑦ Battery clearly marks with positive and negative. When connect the battery with the charger or printer,
be sure to verify the correct battery orientation. Reverse insertion will cause the reverse charging and
may cause abnormal chemical reaction, and then may cause the battery overheating, burning or explosion.
⑧ Do not make the battery (+) and (-) connect with any metal. Also, do not carry along or store batteries
with metal objects, such as necklaces, hair clips and so on. Battery internal short circuit may cause
excessive current, and lead to the battery overheating, burning or explosion and the adjacent metal objects
(necklaces, hairpins, etc.) may be overheated.
⑨ Do not throw or heavily attack the battery. If internal safety device of the batteries burned, the battery
charging may cause abnormal current and voltage, and abnormal chemical reaction, and lead the battery
overheating, burning or explosion
