To replace the LR44 battery in the VEWINGL XT-50 Calculator, please follow these step-by-step instructions:
1. Make sure the calculator is turned off. If it is on, press the shutdown key (OFF) to turn it off.
2. Locate the battery compartment on the back of the calculator. It is usually a small rectangular compartment with a sliding or hinged cover.
3. Use your fingernail or a small tool to slide or open the battery compartment cover.
4. Take note of the orientation of the existing LR44 battery. The positive (+) and negative (-) terminals should be clearly marked on the battery and inside the compartment.
5. Carefully remove the old LR44 battery from the compartment, taking care not to damage the contacts or other components.
6. Take the new LR44 battery and ensure it is the correct type and size for the calculator. Align the positive (+) and negative (-) terminals of the battery with the corresponding markings inside the compartment.
7. Gently insert the new LR44 battery into the compartment, making sure it is securely in place.
8. Close the battery compartment cover by sliding or snapping it back into place.
9. Turn on the calculator by pressing the turn on/clear entry key (ON/CE).
Your VEWINGL XT-50 Calculator should now be powered by the new LR44 battery. If you have any further questions or encounter any issues, please refer to the product manual or contact VEWINGL's customer support for assistance.
