Fixing the System

If pictures in a picture presentation do not display in the correct order:

Pictures are displayed in alphanumeric order based on the file names. Insert the memory card in a computer and rename the pictures files so they appear in the desired order.

If a memory card does not work with the projector:

Only certain types of memory cards are supported by the projector. See “Supported types of memory cards” on page 38.

The memory card might not be formatted with a supported file structure. You can insert the memory card in a computer and format the card with a FAT or MS-DOS file system.

If a presentation file is not listed or does not open:

Insert the card in a computer and check the file name. The three-letter extension of the file name must be one of the supported extensions. See “Supported types of presentations” on page 38.

The content of the presentation file may not be compatible with the type of file expected. On a computer, open the file and resave it in one of the supported formats. See “Supported types of presentations” on page 38.

Hardware problems

If a USB mouse or keyboard does not work:

During a presentation from a memory card, a USB mouse or keyboard performs only navigation functions.

During a network presentation from a computer, a USB mouse or keyboard works only if the projector remote control option is selected.

A USB mouse or keyboard is not supported under other conditions.
