easiest way to set clock time. Remove AA battery's if installed.
Unplug Clock from AC. Wait a few seconds. Then replug clock into AC power. Clock will now flash 12:00. Press hours button until correct time is set PM has led on AM has Led off. Set minutes to correct minutes. Then press alarm reset / power/mode button. Wait a few seconds and display will show correct time. Now you can put the AA batteries back in.

1- Turn over your Seth Thomas digital clock. Use your finger to remove the cover to the unit's battery compartment. Insert two AA-size alkaline batteries into the battery compartment and replace the cover. Certain Seth Thomas digital clock units will also have an optional alternate power source in the form of a standard AC power cable that plugs into a wall outlet in your home.

2 Place your Seth Thomas solar-powered digital clock in front of a light source, such as on a window sill or beneath a lamp. The black strip on the top of the unit is the solar sensor, so as long as light is shining down on that strip, your clock will be powered on and ready to use. The sensor stores energy throughout the day so that it can work at night with no direct light contact on the sensor.

3 Press the time zone button that indicates your current time zone. These buttons are located on the back of the unit. For example, if you are in the eastern time zone select the "EST" button. Turn the unit back over. It will now be displaying the correct time on its digital screen.

4 Use the "Alarm" switch (if applicable) to enable and disable the clock's alarm. Press the "Alarm" button, followed by the "Hour" and "Minute" buttons, to set the appropriate alarm time based on your needs. Use the "Alarm HI LO" switch to set the volume for the alarm.

5 Press the "Weather" button to tune your Seth Thomas digital clock to its built-in local weather radio station (if applicable). Certain Seth Thomas clocks have this radio weather functionality built in, while others don't. If yours does, the aforementioned "Weather" button will be located on the front of the unit.

You can try to take the battery out of the clock/radio and disconnect the plug. This will allow the microprocessor to lose power and reset itself to the factory set-up. It will take about a hour to make sure its discharged. Then put the battery back in the clock/radio and see if the functions return to normal.
