5. Trouble Shooting:
1) Missing power cord, or instructions, please contact us on Amazon or by email for a new
replacement.
2) Please understand the temperature sensor is pre-set inside the clock. As electronic
components may produce heat when working. So it’s normal that the temperature is not as
accurate as other professional thermometer. It’s normal there are 1-2 degrees difference.
The temperature cannot reset manually because it’s detected by sensor automatically. If
the difference is higher than 5 degrees, please contact us for a new replacement.
3) If some numbers are getting dimmer or flash constantly, please take a picture or a short
video and contact us for a new replacement.
4) Please use the original power cord and adapter to work. If it’s broken, please contact us
for a new power cord & adapter.
5) If you find the clock fails to remember settings. That’s because the CR2032 memory
battery has run out of its power. You have to take out the battery shelf on the back of the
clock to change CR2032 battery.
6) If you happen to find that the screen is not lit, please try unplugging and reconnecting the
power cord, and pressing the RESET button on the back of the alarm clock. If the issue
persists, please contact us for a new replacement.
