Q: After changing the battery, the display only shows the degree symbol and HOLD appears when I press the button

This symptom is generally related to a poor initialization after changing the battery or a poorly inserted battery. Here’s how to resolve it: Check the battery insertion Open the back compartment and check that the 9V battery (type 6LR61 or 6F22) is properly seated in the slot, respecting the + and - polarities indicated Remove the battery for a few seconds, then reinsert it firmly Close the compartment securely Clean the contacts Residues or oxidation on the contacts can prevent proper communication with the battery. Remove the battery and gently wipe the metal contacts in the compartment with a dry, clean cloth. Reset the device After reinserting the battery, let the device rest for 10 to 15 seconds before the first use. The screen should normally display the temperature after a measurement. If only the symbol "°" persists, it means no measurement has been taken - this is a normal display waiting for use. Test the operation Aim the device at an object at room temperature and press the trigger. The temperature should display immediately, and the word "HOLD" will automatically appear for 7 seconds to keep the reading visible - this is normal operation. If after these steps the display remains stuck on the degree symbol with no response to the trigger, the battery may be defective (preferably use a new battery from a recognized brand) or the device may have an internal fault requiring repair.
