Motorola MC9090 Device Reset Instructions

Windows CE 5.0 Devices

There are two reset functions, warm boot and cold boot. A warm boot restarts the mobile computer by closing all running programs. A cold boot also restarts the mobile computer, but erases all stored records and entries in RAM. Data saved in flash memory or a memory card is not lost. In addition it returns preferences and other settings to the factory default settings. Perform a warm boot first. This restarts the mobile computer and saves all stored records and entries. If the mobile computer still does not respond, perform a cold boot.

NOTE: Imager decoding usually occurs instantaneously. The mobile computer repeats the steps required to take a digital picture (image) of a poor or difficult bar code, as long as the trigger remains pulled.

NOTE: Scanning procedures depend on the application and mobile computer configuration. An application may use different scanning procedures from the one listed above.

Scan LED Indicators:
LED Status Indication
Off: Not scanning.
Solid Red: Laser enabled, scanning/imaging in process.
Solid Green: Successful decode.


Performing a Warm Boot

Hold down the Power button for approximately five seconds. As soon as the mobile computer starts to perform a warm boot release the Power button.


Performing a Cold Boot

A cold boot restarts the mobile computer and erases all user stored records and entries that are not saved in flash memory (Application and Platform folders) or a memory card.

NOTE: Never perform a cold boot unless a warm boot does not solve the problem.

Windows Mobile 5.0 Devices

There are two reset functions, warm boot and cold boot. A warm boot restarts the mobile computer and closes all running programs. A cold boot also restarts the mobile computer and closes all running programs but also resets the Real-Time-Clock (RTC). Data saved in flash memory or a memory card is not lost. Perform a warm boot first. This restarts the mobile computer and saves all stored records and entries. If the mobile computer still does not respond, perform a cold boot.


Performing a Warm Boot

Hold down the Power button for approximately five seconds. As soon as the mobile computer starts to perform a warm boot release the Power button.


Performing a Cold Boot

A cold boot restarts the mobile computer. The operating system and all applications are restarted. File storage is preserved. The Real-Time-Clock (RTC) resets.

NOTE: Only perform a cold boot if a warm boot does not solve the problem.

CAUTION: Do not hold down any key, other than the Power button during a reset. Performing a cold boot restores formats, preferences and other settings to the default settings.

NOTE: Any data previously synchronized with a computer can be restored during the next ActiveSync operation.
