Press the Message Stop key (which may have the word Stop on it or an oblong black rectangle depending on the version you have), just to the right of the Play key, and hold it down for a couple of seconds and then release it. It will announce the currently set day.
If the Day is correct, press the Stop Key again and release it. It will announce the currently set Day and Hour.
If they are correct, press the Key again and release it. It will announce the currently set Day, Hour and Minute.
If they are all correct, leave it and it will confirm the setting.
If at any stage you want to alter any segeny of the announced setting, use the Message Forward key or Message Backward key, probably located to the right of the unit, just after it has announced the "incorrect" setting. At each depression, they will announce the new setting. When it is correct, press the Stop key again and release it to move to the next part.
You do not use the Plus and Minus volume keys, which at first sight would appear to be the logial ones to use.
Hope that helps.
