Troubleshooting: clock showing the wrong time

Off by exactly 5 h 30 min? The clock is probably set to GMT instead of Local Standard Time — change the Local/GMT setting.
Showing 1:00 instead of 13:00? Switch between 12-hour and 24-hour mode.
GPS clock not updating? Check the antenna has a view of the sky and the cable is firmly connected; allow a few minutes after power-up.
WiFi clock not updating? Confirm the WiFi network or hotspot is available and the clock has been joined to it.
Display dim or too bright? Adjust the brightness setting (High/Low, or High/Medium/Low on multicolour models).
Still wrong? Power the clock off and on again. If the issue persists, raise a support request with your model and serial number.
