General Information

To place the clock in the program mode, set the program switch located on back of clock in the upper left corner from NOR to PRO (top position). This now activates the six manual card-positioning switches (IN1, OUT1, etc.) on top of the clock to function as program switches. With the dust cover open you will find that these program switches are numbered 1–6 to simplify programming the ATR120.

The first switch on the top left of the clock (IN1) functions as the feature selection switch and will advance you through the program mode. This switch also allows you to skip over a feature and advance to the next feature without programming. Once a feature is selected, switches OUT1 through IN3 will be used for programming.

The last switch on the right (button six or OUT3) is used to save the program selection to memory. IMPORTANT: If OUT3 is flashing in the lower right corner of the display, the programmed changes have NOT been saved.

Setting Daylight Saving Time

The starting and ending dates for Daylight Saving Time must be set each year. Both the starting and ending dates must be set for Daylight Saving Time to be operational.

At midnight on the starting date, the clock will automatically advance one hour. At midnight on the ending date, the clock will go back one hour. For example, on the first date of Daylight Saving Time, the clock will advance from midnight to 01:00. At midnight on the last day, the clock will change from 00:00 to 23:00.

To set the starting and ending dates for Daylight Saving Time:

Setting the Time Displayed on the Analog Clock Dial

The Daylight Saving Time settings outlined above will automatically adjust the digital display and the printer to and from Daylight Saving Time. You will need to manually reset the analog clock dial to synchronize it with the digital display and printer when the time changes.

The front cover must be opened to set the clock's analog time.

To open the front cover, turn the clock on its back and remove the two outer screws on bottom of clock. Stand the clock upright with the back facing you. With both thumbs press down on IN1 and OUT3 buttons while using your fingers to push cover away.

Once the front cover is open, you will be able to set the time on the dial.

Setting the Time Manually

If you have not set the Daylight Saving Time program as outlined above, you will need to manually set the digital display and printer to the correct time when the time changes.

When programming the time, the display will show time in a 24-hour format (i.e. 3:00 PM will be 15:00).
