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.
