How can I get intructions to adjust the data on my RCA WERE 1001 Made in China Black oval approx 5 1/2 " high weather station?

Sorry, I was wrong about how you get the WERE 1001 to enter the set mode. All you have to do is press and hold the set button for about two seconds. The unit will beep, and enter the set mode, beginning with the 12 or 24 hour format. year. Use the + or - buttons to set your desired time format. Then hit set, and you will move onto the year. Use the + or - buttons to set the unit to the correct year. Then press set again to enter the correct month, again using the + or - buttons. Continue to hit set after each new entry. If you make a mistake, you must go through the whole set functions to set the unit anyway. After it is set, hit set again for two seconds and wait for the unit to enter set mode again. Hit set until you get to the part where you entered the incorrect info and then correct it wit the + or - buttons.

Hope this helps! I have had my unit since 2006 and am very pleased with it. Sorry, I was wrong about how you get the WERE 1001 to enter the set mode.
