What do I do if my iPod nano freezes up? A frozen, or unresponsive, iPod nano is one of the most common problems that can occur. Fortunately, it also has one of the easiest solutions.

There are several possible reasons and several solutions. It could be that your software needs to be updated. Go to the Web address above to download the latest version of the iPod Updater software and iTunes. Install both files and update your iPod nano.

There are several icons that your iPod nano can display that indicate problems with the iPod or portions of its program. If you see either a folder or a sad iPod with an exclamation point, first fully charge your iPod nano. If you still see the icon, try resetting and restoring your device. Make sure you're using the most up-to-date version of the iPod Updater software. If none of these steps works, you might need to have your iPod nano repaired. Go to depot.info.apple.com/ipod to set up a service request.

Your iPod might have the maximum volume limit set. This feature limits the volume when any headphones are attached to the headphone jack. To set this feature, disconnect all accessories from your iPod nano except your headphones and select Settings and then Volume Limit. Use the Click Wheel to select the maximum volume you want by moving the volume indicator bar and pressing the center button to continue. The small triangle will move once you’ve pressed Select. You can also set a password to keep the limit where you set it by clicking the center button and then setting a numeric password. This way no one can change the maximum volume without knowing your password.

Sometimes, so-called pixel anomalies can affect the way your iPod nano displays content on its screen. The iPod nano uses an active-matrix LCD (liquid-crystal display) to provide its color display, which has many performance advantages over traditional CRT (cathode ray tube) technology (the technology used by older TVs and computer monitors). The active-matrix LCD contains hundreds of discrete pixels which have red, green, and blue elements that display information. Sometimes, these pixels malfunction and cause anomalies. Because it would be very expensive to reject all but perfect LCDs (that cost would be passed to you, the consumer), occasionally an anomaly will occur. This is a problem with all LCD technology?/font>not just iPod nanos. But if you feel that your iPod nano contains a high number of anomalies, take it to an Apple store or go to www.apple.com /support/ipod/service to find out how to have it serviced.

Some users claim the player scratches extremely easily, enough that it makes the screen difficult to read.
