If your device’s time settings are resetting upon restart, the issue might be with the internal button cell battery, specifically a CR1220 – 3V. This battery is crucial as it maintains the internal clock and preserves the time settings even when the device is powered off or restarted. To address this issue, you should replace the old button cell with a new CR1220 – 3V battery, which can be purchased from a local electronics store.
Replacing the battery should stabilize the time settings, ensuring they remain consistent through restarts or power interruptions. This simple maintenance step is vital for ensuring accurate timekeeping in your device, thereby preventing any potential disruptions caused by incorrect time settings.
