Equity model 40018, lost program manual, DST setting ahead 1 hour , need to reset for mother in law 74 yrs of age. Thanks

Model 40018: You do not need the 9-volt battery to operate this clock.

If the display is blank when plugged into the AC outlet, unplug from AC power and remove the Insta-Set battery (lithium button cell), then plug into AC power again and manually set the Time and Date.

After completing the manual set for time and date, insert a fresh Insta-Set button cell battery and the settings will automatically be stored in the clock.

Instructions

Press and hold the "Alarm Set" button for five to seven seconds and the year will begin to blink when the clock is ready for adjustment. .

Set the year by pressing the right-arrow, "Up" or "+" button, depending on your model of clock.

Set the month, day, hour and minute. Press the "Alarm Set" or "DST" button to cycle through each field, and use the "Up," "+" or right-arrow button to adjust the values within each field.

Press the "Alarm Set" or "DST" button after setting the date and time to store the information into your clock's memory.

Press alarm 2 to change from Celsius to Fahrenheit.

Press alarm 1 to change from 24 hr time to 12 hr time.

Slide the Wake 1/Wake2/Clock switch to the Clock position. Then press the forward button to advance the clock by the needed amount of time. Then slide the switch back to the side with the key icon.

If you set the DST switch to ON, you can move the time zone switch to one time zone further east for a few weeks until the DST change in the program takes effect. Then move the time zone switch back to your current time zone. (Repeat this in the fall to correct for the later change in DST again). The exact length of time between when DST starts and ends versus when the clock will change the program will depend on when the clock was manufactured. Clocks built after July 2006 should have the correct DST programs. Clocks from earlier have a much shorter period of DST (April through Oct).

I hope this helps.

if you hold down the button on top that says DST for like 10 seconds it will allow you to force change the time.

This solution from the answers below worked on my model 40007 clock today: If you hold down the button on top that says DST for like 10 seconds it will allow you to force change the time.
Thanks. wd 11/21/2010

I read the manual which said to depress the alarm button. That wasn't the right button but I found that depressing the button next to it, the DST button, that that fixed the problem.
Thanks.

For any Equity clock, press and hold down the Alarm Set button. First the year will flash, if you don't care about the year, press the Alarm Set button again, if you do care about the year, press the arrow button (it could be an UP/DOWN arrow or a side arrow which is usually used to change from Centrigrade to Fahrenheit).
Basically, you begin by pressing and holding the Alarm Set button, then you use the arrow buttons, then again press Alarm Set to go to the next thing you want to set. If you wait too long, it will not set it, so begin again. I do this all the time, esp when DST occurs as the clock, when manufactured did not have the rules for the new DST time.
