3.2 Battery use and care
The capacity of Lithium battery will be changed by it’s using condition. For maximum battery capacity, use the battery
in room temperature(10 ℃~40 ℃). Do not expose the battery to extreme temperatures, if the battery is used in high or
low temperatures, the battery capacity will be reduced.
3.3 Cleaning and sterilization
• The outer surface of the instrument may be cleaned with wet cloth, the remaining stains can be cleaned off with the
mixture of 50% alcohol and 50% distilled water. Do not wipe with any corrosive detergent lest that the surface should
