Before Use - Problems or issues related to the use of third-party cartridges are not covered by the warranty. - To protect the screen during production and distribution, screen protective films are affixed, but might not be attached depending on the region or distributor. Damage to the protective film is not covered by the warranty. - Press the power button for less than 1 second to power off when not in use. 1.1. Waterproofing and dustproofing 1) Waterproof and dustproof functions are not supported by this product. Do not submerge in liquids, such as brine, ionized water, or water with alcohol. 2) If the product is submerged in water, use a dry cloth to wipe it, then dry it thoroughly before use. 3) Avoid drops and impacts to the product to decrease the risk of damage. 1.2. Battery heating while in use or charging 1) If there is heat while charging the battery - The SOL COUNT Automated Cell Counter and charger might heat up during charging. This is normal, and the life and function of the product are unaffected. - If the product heats up, disconnect the charger and press and hold the power button for at least 3 seconds to power off. Let the product cool before attempting to charge it again. - If the power port behind the product is very hot, it is possible that the connected USB C-type cable is damaged. In that case, replace it with a new USB C-type cable. 2) In case of heating during product usage - When the cell counting algorithm is running, battery consumption temporarily increases, and heat may be generated. Press and hold the power button for more than 3 seconds to power off. - Do not place the product in direct sunlight or near items t…
