How do I adjust the ATR440 for the Daylight Saving Time Change (DST)?

Basic programming instructions

The programming mode is entered by unlocking and removing the top cover from the ATR 440 with the power on. The IN/OUT buttons on the clock serve as function keys in the programming mode. The functions of each button are listed below and on the inside cover of the recorder.

Setting Daylight Saving Time (must be set each year)

Daylight Saving Time is not automatically updated each year. You will need to reset it each calendar year. You must set both the starting and ending dates for Daylight Saving Time. The clock will then automatically advance forward one hour on the first date you set, and revert backwards one hour on the second date you set.

1. Open the top cover. The digital display reads P1.
   
2. Press the F4 button.The digital display shows a 1 as the left-most character, representing the first or starting date of Daylight Saving Time. The hour, next to the 1 on the left-hand side of the display, flashes.
   
   Press the + or – button to change when the time change takes place. Currently, the U.S. standard is 2:00 am on the second Sunday in March and on the first Sunday in November. Any hour between midnight and 9:00 am may be chosen as the time for the clock to advance forward or to revert backwards. To accept the hour, press the E button.
3. The month flashes next.
   
   Press the + or – button to change the starting month. If you are setting the standard U.S. Daylight Saving Time, this should be the month of March. Press the E button to accept the month.
4. The day of the month will flash next.
   
   Press the + or – button to change the day. If you are setting the standard U.S. Daylight Saving Time, this should be the second Sunday in March of the current year. Press the E button to accept the date.
5. You will now start setting the Daylight Saving Time end date. The digital display now shows a 2 as the left-most character. This represents the second setting or ending date. The hour on the left-hand side of the display flashes.
   
   Press the + or – button to change to the hour which you want the time change to take place. To accept the hour, press the E button.
6. The month flashes next. Press the + or – button to change the ending month. If you are setting the standard U.S. Daylight Saving Time, this should be the month of November. Press the E button to accept the month.
