20 Most Recent RCA OPAL M4001 MP3 Player Questions & Answers


I had this same problem on another RCA player.. with no instructions manual it was hard to figure out what keys locked meant. Then I noticed a little slider on the side of the player, it has a little icon of a pad lock on it. Once I slid this back, the keys lock problem went away and I was able to listen to my music once again.

My best guess of what keys locked means.. you don't want you mp3 player to turn on when you put it in your pocket with your keys, so you change the slider to be locked, when your sit down and your keys are pressing against your on button, the mp3 player will shut off... as we all have experienced in frustration.. saving your battery.

Perhaps RCA should make this slider bright orange so it pops out and does not blend in so much, or they should put it right next to the on button.

Go to eBay,and look for the USB cable( About $ 4.00) for the iPod nano, it works for the Opal,I ordered one,and it is fine.It has a USB connector on one end,and the plug for the Opal.You plug one end where the earplugs go,and the USB connector on your computer.You have to let it charge at least for 3 hours.

If the player is showing up in your Windows' Device Manager under "portable devices" with a yellow "!":

1.) Right-click the yellow "!" and choose "update driver".
2.) When given the option to connect to Windows Update, choose "no, not this time" and click next.
3.) Choose "Install from a specific location (advanced)" and click next.
4.) Choose "Don't search. I will choose the driver to install" and click next.
5.) Click the "Have Disk" button. Browse to C:\Windows\inf and choose the file marked "wpdmtp.inf"

I can't believe the generic players have such crappy support when so many people have this problem! I think the Windows file problem might be caused by "compressing old files" when you do a disk cleanup.

Hold in the volume + button, and then reconnect to computer while holding in the volume + button, after 10-30 seconds of holding in volume +, a Found New Hardware Wizard should pop up.

ON THE BACK OF THE MP3 PLAYER THERE IS A RESET BUTTON YOU CAN CLICK IT WITH THE BACK OF AN EARING. WAIT A LITTLE WHILE AND IT SHOULD BE WORKING LIKE IT'S BRAND NEW.
