Clean system components

Use the information in this section for system and component cleaning.

CAUTION

•Always turn OFF system power before cleaning.

•Do NOT use any abrasive cleaners on system enclosure surfaces.

Instructions

•Clean the system by gently using a soft cloth dampened with water or a mild cleaning solution.

•Clean the monitor by using pre-moistened towelettes that are sold specifically for monitor cleaning. If these are not available, use a non-solvent based cleaner to dampen a soft cloth.

•Clean the barcode scanner window regularly by wiping the scanner window with a clean, dry, cotton-tip swab or cotton cloth.

•Clean paper dust from the printer with a compressed air duster.

Adjust the touch screen monitor

Touch screen monitor display characteristics are preset at the factory. Do not attempt to change monitor settings — no user serviceable parts inside the system enclosure — contact 3M Service for repair.

If you wish to make adjustments, use only the Display Properties adjustments available in Windows.

Note: Changing the touch screen display resolution is not recommended, since the default resolution of 1280 by 1024 is optimized for the system graphics.

Adjust audio volume

Use the Volume icon in the Windows® taskbar to adjust the system volume level, which requires the use of the mouse or touch screen.
