One of the major warnings Apple includes with all of its iPods is the permanent hearing damage that could occur if you have the volume on your iPod turned up too high.

To help combat the problem, the iPod comes with a feature that allows you to set a maximum volume level that your iPod can be played at that level is controlled by a combination that can keep others namely children from turning the volume up to dangerous levels.

The good news is, if that combination falls into the wrong hands, it can be reset.

Use your iPod's click wheel to scroll down to "Settings."

Press the center button located in the middle of the click wheel to select the settings menu.

Scroll down to "Playback" and press the center button to select it.

Scroll to "Volume Limit" and press the center button to select it.

Use the click wheel to scroll to the first number of the old combination and press the center button to select it.

Repeat this process for all four numbers of the old combination.

Use the click wheel to scroll to where you want the maximum volume to be set and press the center button.

Use the click wheel to scroll to "Lock" and press the center button.

Use the click wheel to enter the first number of the new combination when the message "Enter New Combination" appears on the screen repeat the process for the three remaining numbers.

Once the four numbers have been entered, your iPod's maximum volume will be set and your password will be changed.

Resetting the volume limit on your iPod Nano affects everything you listen to, from music to audio books. You can adjust the volume for each individual item on your Nano using the click wheel, but the highs and lows of the sound will depend on the overall volume limit setting. Volume levels will vary with different ear buds and headphones, and using external devices like docking stations to play your iPod Nano will also cause variation in the volume.

Instruction:

1 Press any button on your iPod Nano's click wheel and turn it on. Press the "menu" button at the top of the click wheel until you reach the iPod menu.

2 Select "Settings" from this menu by scrolling down until "Settings" is highlighted, then click the center button.
3 Select "Playback" from the menu choices that show up.

4 Select "Volume Limits." You will reach a screen with a speaker icon and dots indicating the level of volume your iPod is currently set on.
5 Scroll the wheel up or back to adjust the volume limits. Press the center button and you will have the option to lock in your settings by selecting a four-digit combination lock. This is not a necessary step; you can click on "done" and finish. Setting the combination allows you to have more control over any future changes to your iPod's volume limits. Scroll the click wheel to select your combination. Press the center button and you will revisit the volume limits; adjust it as you like and press the center button.

Goodluck
