If the printer is to be stored for a long time, be sure to remove the battery from the printer and store it
separately; otherwise, the battery may fail or even have leakage, which may damage the printer.
Make sure the printer is turned off before replacing the battery. If a power adapter is used, make sure
the power is cut off before replacing the battery.
The printer can work stably at an ambient temperature of 0C-40℃. Too high or too low ambient
temperature will lead to low printing quality.
The time that the printed text can be kept on the thermal printing paper is related to the paper quality.
To print documents that need to be kept for a long time, please use long-lasting thermal printing paper.
Please carefully read this Manual and symbols on the battery surface before use.
Please charge the battery in a cool and ventilated room. The high ambient temperature during
charging will cause the battery to heat up, emit smoke, burn, deform, or even explode.
There are special protective circuits and devices inside the battery. Please do not disassemble the
battery by yourself, or it will cause a short circuit or electrolyte leakage.
There is a risk of blindness if the electrolyte gets into the eye. In case of eye contact, rinse immediate-
ly with water and seek doctor's advice immediately.
Do not squeeze, mechanically vibrate or shake the battery, and short circuit of the battery is strictly
forbidden.
