What to do if my Famidoc FDTH3400 Thermometer screen doesn't turn on?

If the screen of your Famidoc Thermometer does not react when the power is on or when equipped with batteries, it could be due to a few reasons: * The battery might be depleted, so please replace it with a new one and try reopening the device. * The battery might be installed incorrectly. Ensure that you have installed the battery correctly, paying attention to the positive and negative pole markings in the battery compartment.
