DANGER  DO NOT use the rechargeable battery with the polarity (+) (-) reversed. Check the orientation of the rechargeable battery before inserting it, and do not try to force the rechargeable battery into the scanner. Charging the rechargeable battery with the polarity reversed could cause an abnormal chemical reaction within the rechargeable battery or abnormal current flow during discharge.  DO NOT directly connect the rechargeable battery to a household electrical supply.  Liquid (electrolyte) leaking from the scanner or rechargeable battery may indicate that the rechargeable battery is damaged. If the rechargeable battery leaks, immediately discontinue use of the scanner, unplug the cable, and isolate the scanner by putting it in a bag. Do not touch the electrolyte. If electrolyte gets in the eyes, do not rub the eyes. Immediately rinse liberally with tap water or other clean water and seek the advice of a medical professional. If left alone, the electrolyte could cause eye damage. If electrolyte contacts your skin or clothing, immediately rinse them with water.  DO NOT put the rechargeable battery, or a scanner with the rechargeable battery installed, into a microwave oven or a high pressure container.  DO NOT leave the rechargeable battery with out of power in the main unit for a long period of time. This could shorten the life of the rechargeable battery or lead to an electrical short.  If the scanner can only be used for a short period of time, even though the rechargeable battery is fully charged, the rechargeable battery may have reached the end of its service life. Replace the rechargeable battery with a new one. When removing and replacing the rechargeable battery, cover the terminals of the old rechargeable battery with tape to avoid creating a short in the battery.  DO NOT disassemble, modify, or attempt to repair the rechargeable battery.  DO NOT dispose of the rechargeable battery in fire or intentionally overheat. This could cause the internal insulation to melt, gas to be emitted, or safety mechanisms to fail. Additionally, the electrolyte solution could catch fire.  DO NOT puncture the rechargeable battery with any objects, subject it to severe shocks or throw it. Damage to the rechargeable battery's protection circuit could cause the rechargeable battery to be recharged at an abnormal current/voltage or cause an abnormal chemical reaction within the rechargeable battery.  DO NOT incinerate the rechargeable battery or dispose of it with household waste. WARNING  Store the USB cable bundled out of the reach of children to avoid the risk of injury.  Do not disassemble or modify the unit. This may result in a fire, electric shock, or device failure.

Contact the store where this unit was purchased.  In the event that foreign material enters the unit, turn the power switch off immediately, remove the USB cable. Contact the store where this unit was purchased. This may result in a fire, electric shock, or device failure. WARNING  Do not spill drinks, i.e. coffee, juice, etc., or water on the device. Do not use the device in places where water may splash the device. This may result in igniting a fire, electric shock, or device failure. In such a event turn the power switch off immediately, remove the USB cable from the outlet. Contact the store where this unit was purchased.  Keep plastic bags bundled out of the reach of children or throw them away to avoid the danger of suffocation.  Do not place near open flames or heater. This may result in a fire or device failure. CAUTION  Strong jolts, i.e. drop, being stepped on, etc., may damage the unit. This may result in injury. In the event that the unit is damaged, turn the power switch off immediately, remove the USB cable from the outlet. Contact the store where this unit was purchased.  RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.  Do not locate the device on rackety or aslope tables. Do not locate the device on unstable surface. The device may fall down and this may result in injury.  Do not place heavy objects on the unit. It may cause unbalance and the device may fall down. This may result in injury.  Do not use an organic solvent, i.e. flammable gas, alcohol, etc., when cleaning the device. Do not use them near the device. This may result in a fire or device failure.  Be cautious when you handle paper. Edges of paper may cut your hands. IMPORTANT  Do not leave the device at places exposed to direct sunlight and places near open flames or heater with extremely high or low temperature. Do not use and store the device in locations of much humidity and dust.  Do not conduct any operations not instructed in this guide. This may result in injury or device failure.  Do not use an organic solvents, i.e. paint thinner, benzene, alcohol, etc., when cleaning the unit. This may damage the finish on the surface or may peel the paint resulting in damage. Wipe away any dirt on the unit using a soft, dry cloth.  Do not use any USB cables except the USB cable bundled.  Do not use the device in locations where temperature changes are extreme. The resulting condensation may result in device failure or malfunction. In the event of condensation, use only after drying the device naturally.
