4. Maintenance
4.1 Battery Replacement
When the screen dims or the device stops responding, it's time to replace the battery. Your Tamagotchi uses one CR2032 nonstandard battery.
- Locate the battery compartment on the back of the device.
- Use a small screwdriver to open the compartment.
- Carefully remove the old CR2032 battery.
- Insert a new CR2032 battery with the positive (+) side facing up.
- Securely close the battery compartment.
Warning: Contains button or coin cell battery. Hazardous if swallowed. See instructions.
4.2 Cleaning
To clean your Tamagotchi, gently wipe the device with a soft, dry cloth. Do not use liquid cleaners or immerse the device in water.
5. Troubleshooting
- Tamagotchi dies quickly: Ensure you are not overfeeding snacks, as this can lead to illness. Provide consistent care, including feeding, cleaning, and discipline.
- Screen is dim or unresponsive: Replace the CR2032 battery.
- Tamagotchi constantly beeps: Check the Health icon to determine its needs (hunger, happiness, discipline, illness). If no need is apparent, use the discipline function.
- Device reset: If your Tamagotchi is not functioning correctly, you can reset it by pressing the reset button located on the back of the device with a pointed object (e.g., a pen tip). Note that resetting will restart your Tamagotchi from the egg stage.
