My RCA s1010 Sport flash-player wont turn on, hold is off?

I changed the batterys to new ones. It worked for about a week then when I tried to turn it on next it wouldent. SO i changed the batterys. Just today my ipod nano wouldent turn on so i looked for help online and it told me how to restart it so it would turn on. it was like frozen. but i restarted it and it worked, so i thought of doing it to my RCA. SO, does anyone know if there is a way to turn it on or restart it? Maybe there is a combination of buttions to press for an ammount of time?
THANKS!!
