In today's daily life, electronic calculators are no longer the main tool for calculation. However, there are still many regions and occasions where electronic calculators are needed. Below are some tips for maintaining electronic calculators.
Steps/Method
Replace the battery in time: When the displayed reading becomes dim, it indicates that the battery has been exhausted. It should be replaced in time. If the calculator is not used for a long time, the internal battery should be removed to prevent battery leakage from corroding and damaging the calculator.
Prevent Crushing: Avoid Hitting or Dropping: Both the fluorescent digital display calculators and the LCD display calculators have glass display components that are easily broken. These components should be strictly protected from being crushed, hit, or dropped to prevent damage.
Pay attention to the use environment: The LCD calculator can only be used in the temperature range of 0-40 degrees Celsius, and it is not suitable for use in direct sunlight due to the ultraviolet rays in the sun that can accelerate the aging of the LCD screen. It is also not suitable for use and storage in humid and corrosive gas environments, to avoid damage to the machinery.
Keep dust-free: After use, put it into a leather case or plastic cover to prevent dust from entering. If there is dust on the panel, use a soft cloth to gently wipe it, but do not use chemicals such as gasoline, ethanol, or banana oil to clean it.
