3.1 Resetting the Aero 8000 During a severe system lockup or when a malfunction cannot be corrected any other way, you may need to completely reset and restart your device. Your Aero 8000 can be reset two different ways, depending upon your situation and the action that is called for: normal reset, which does not affect data that has been saved in memory, and full reset, which erases memory contents and settings. 3.1.1 Performing a Normal Reset A normal reset restarts your Aero 8000 much like pressing Ctrl + Alt + Del restarts a computer. To perform a normal reset, follow these steps: 1. Save all work (if possible). 2. Close the lid and turn over the device. 3. Using a paper clip, press the reset button and the device automatically restarts. Resetting the Device

A full reset restarts your device and removes all information that was stored in memory, such as your data files and your system settings. To perform a full reset, follow these steps: 1. Disconnect the device from the AC adapter if using external power. 2. Close the lid and turn over the device. 3. Remove the main and backup batteries. 4. Wait at least 5 minutes, then replace the batteries. 5. Turn over the device, open it, and press the power button to restart the Aero 8000. 6. Run through the Welcome Tour again to reestablish your system settings. NOTE: If you previously saved data using the backup utility, you will be prompted to restore your saved data. Select Yes if you wish to do so. 3.2 Using the Compaq Unlock Utility The Compaq Unlock Utility is used to generate an unlock key that allows a user to regain access to an Aero 8000 unit that has entered either the lockout or administrator lockout modes. The Compaq Unlock Utility is an integral part of the enhanced security built into the Compaq Aero 8000 Handheld PCs. Within the unit security, the user has the option to force the unit into a "lockout" mode if an incorrect password is entered too many times. After five unsuccessful attempts, the unit enters the first lockout mode. At this point the user must enter the Admin password (if defined) or enter an unlock key. This key is generated by the Compaq Unlock Utility. The user enters data provided on the screen of the HPC, and the Unlock Utility on the desktop generates an unlock key (an alphanumeric string), which is entered into the HPC to recover from lockout mode. The Compaq Unlock Utility is available through the COMPAQ AT HOME web site, http://www.goesd.com/Compaq. If you plan to use the advanced security, purchase the Compaq Unlock Utility before you need it. 3.3 Solving Audio Problems Problem Possible Cause Solution I cannot get sound from my device.
