Device Firmware Update (DFU) Restore
Device Firmware Update allows you to perform a restore when all other attempts to restore the 
device fail. 
DFU is only necessary if:
• the device won’t turn on 
• the device won’t go into recovery mode
• the device won’t charge
To perform a Device Firmware Update follow the step below:
Timing is critical--use a watch to time the steps below!
1. Charge the iPad for at least 5 minutes, then connect to iTunes. If the device is not detected, 
open iTunes and move to step 2.
2.  Power off the device. Wait 5 seconds. If device will not power on/off, move to step 3.
3. Press Home + Power (Sleep/Wake) buttons together and hold down for 8 seconds and 
then release the sleep/wake button.
4.  Continue to press the Home button until you see the “Recovery Mode” message in iTunes, 
which may take up to 30 seconds.
Note: In DFU Mode the device’s screen is blank.
If you did not get the “Recovery Mode” message in iTunes or the device’s screen is not blank/
black, repeat all steps paying careful attention to your timing.

Sensors 
Accelerometer Sensor with iOS 3.2
Detects iPad positioning, movement, and tilt, switches between portrait and landscape modes, 
and functions as the tilt controller for applications and games that utilize this hardware 
component.
Use the screen rotation lock switch on the right side of the iPad to lock the screen in portrait or 
landscape mode. If the display is locked, an indicator appears in the status bar (second graphic).
The lock indicator appears next to the battery indicator, in the top right corner of the display.

Ambient Light Sensor
The ambient light sensor detects light levels at the current location and adjusts the brightness 
of the Multi-Touch display.
The approximate location of the ambient light sensor is circled and marked in orange:
Troubleshooting Notes: 
• Make sure the ambient light sensor is not being blocked or covered. Screen brightness can 
be affected by a screen protector, especially if it covers the ambient light sensor. 
• The ambient light sensor can be defeated using the Settings application.
• The iBooks application includes a screen brightness slider that overrides the iPad screen 
brightness (but only when iBooks is running). Note: There is a slight delay of a few seconds 
before the screen adjusts to ambient light (this is by design, it is not intended to be 
instantaneous).
• Isolate applications that might modify the screen brightness on the iPad and if unsure what 
application might be the cause, restore the iPad to see if it fixes the problem (restoring the 
iPad will remove all 3rd party applications from the device and reset the unit back to factory 
default settings).
