How to set clock on a 1992 oldsmobile achieva
Hello...I believe I can help. With the car on or off, press the SET button. The SET indicator will appear on the screen for only five seconds, so have your fingers ready. Press the SEEK button for the hour...and the SCAN button for the minutes. Good luck.
a picture of the radio would be helpful
If you are just trying to set the stations in, go to the station you want programmed. Then press and hold the number you want it preset to.
With the radio turned off, push the set button. The scan button changes the hours and the seek button changes the minutes.
read the owner's manual
Does your clock have two small buttons marked H and M? If so, those are for setting the clock. Push and hold until they begin to operate. FriPilot
Push the set button and within 10 seconds push the seek and scan buttons to change time.
Turn the radio OFF. You will need to hit the SET button one time. Then use your long buttons on top, (SEEK, SCAN) for your hour and minutes. Good luck!
Press "SET" and then use the keys on the bottom right of the radio.
Press the set buttons for hour and minute.
