Re: mp3 player

If it isn't the 'hold' switch then there is something wrong internally. if you wanna try... sandisk ran me through these troubleshooting steps, hope they help. do one at a time and see if you get a result -Reset device take out battery hold power button for 30 count put battery back in turn device on. -Upgrade firmware Go to website, download firmware update This was the URL at the time of writing this or try Install according to instructions. let the device reboot. -Format memory. turn hold switch on, orange should be visible hold pause/play button and press power. click forward button when the screen comes up. let this run. after reboot flip the hold switch off.

Try to turn on and says key locked shuting down

When an mp3 player is locked and you try to turn it on, it will shut down again. You have the keys locked by the switch on the back. Flip the button that says "LOCK >" to the left to cover the little red dot and it should be unlocked, then try turning it on again.

Key locked system shut down

On the top of the player there is a slider. When it is showing orange next to it your player is "Locked" so accidental button pushing wont mess up your tunes. Slide it over so it shows only white instead of orange and your player should be just fine.

Mp3 player says key locked system shut down

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.

Key lock shut down

On the back of the player there is a button to the right. Above the button it says Off and below it there is a picture of a key. Switch the button upwards to turn the lock thing off.

Most things with "Hold" button don't turn off the device. So I surspect there might be a deeper problem. You could try to check the battery see if it's still good. As last resourt, you could try to open it up and see if some how buttons are permanently pressed. You could even try to power it on without the switches. Most of this MP3 players (the small 1 that uses only 1 battery) are pretty much self contain so there shouldn't be anything wrong.
