Fixing PowerPoint PPT files that display incorrectly from a memory card

If certain elements in a PowerPoint PPT slide are missing or displayed incorrectly, you should check these possible solutions:

• If the slide includes large graphic images or uses several fonts, the slide may

require more memory than available in the projector. Try using fewer fonts, or try using fonts that use less memory (you can check font file sizes by looking in the font folder on the memory card). Or try reducing the memory size of the graphics (see the next topic below).

• Certain PowerPoint features are not supported while presenting a PowerPoint PPT

file from a memory card. Try editing the slide to use supported features (see the second topic below).

Reducing large graphics in a PowerPoint file

A large graphic image may not display in a PowerPoint presentation shown from a memory card due to memory requirements on the projector. You can use an editor to create a smaller image file. Or you can try the following steps in PowerPoint to reduce the size of an image.

1. Right-click the graphic, then select Copy.

2. Click Edit > Paste Special, and select the option to paste in PNG format.

3. Delete the old image.

An alternative solution is creating a mobile presentation PDB file.

Selecting PowerPoint features for a memory card presentation

When you show a PC-free presentation from a memory card, the projector has available only the information stored on the memory card—it does not have access to the Microsoft PowerPoint application. Although the projector provides most of the popular features of PowerPoint 2002, not all features are supported during a memory card presentation. To avoid unexpected problems, select features that are supported for either a PowerPoint PPT file or a mobile presentation PDB file. See the table of supported PowerPoint features at the end of this document.

Creating mobile presentations for a handheld organizer or memory card

You can use HP Wireless Presenter-to-Go to create mobile presentations from PowerPoint. In some situations, a mobile presentation you create may omit certain PowerPoint elements, such as special fonts, vertically oriented text, or arrowheads. If this occurs, try choosing a lower animation setting in the Wireless Presenter-to-Go creator window.

Creating mobile presentations from portrait documents

If you want to create a mobile presentation (PDB file) by printing from an application, you should check the page setup first. If the page has portrait orientation (vertical layout), you should do one of the following to avoid losing the bottom of all pages in your presentation:

• Before printing, change the document to landscape orientation (horizontal layout),

• In the print window, change the printer properties to use portrait orientation

(vertical layout).

Choosing a memory card for presentations

The projector supports several standard types of memory cards, which you can connect to the CompactFlash slot or to a USB port. Such cards are available from HP and many other manufacturers. However, you may find that some memory cards or adapters do not work properly with the projector, such as some USB 2.0 devices. If you have a memory card or adapter that does not work with the projector, try a different brand or type of card. For example, the HP USB digital drive with SD memory card (DG921B) is supported.

Viewing images on a memory card

If you are viewing a picture presentation from a memory card, certain problems may cause a picture to be shown as "X", a missing picture:

• The image is larger than 3.5 MB or requires more memory than available on the

projector. Check file sizes, and edit large images or convert them to JPG format so they are smaller than 3.5 MB.

• The image file is not a valid JPG, BMP, or PNG file.

• The file name contains any of the characters \ / : * ? " < > , | [ ] ; =

Locating ports on the enhancement module

The USB ports on some enhancement modules may be covered by a label. If you want to use these ports, remove the label. Note that use of the audio port is not supported.

Increasing security on the projector

The projector includes several security options for preventing unauthorized access. You can set up all of these security settings using the projector's embedded web server. The first two options are required to secure the projector.

• Admin password. In Networking > Admin. Account you can set a password that

prevents unauthorized access to most settings in the embedded web server. This password protects all other security settings below.

• SNMP community names. In Networking > SNMP you can specify secure

community names for read-only and read-write access to the embedded SNMP server.

• Wireless Presenter password. In Networking > Wireless Presenter you can set a

password that prevents unauthorized network presentations via wired and wireless connections.

• WEP encryption and shared mode authentication. In Networking > Wireless

Settings you can set an encryption key and key index, then use them to

authenticate wireless connections and encrypt wireless data.

• Access control. In Networking > Access Control you can defines ranges of IP

addresses that are authorized to access the projector.

Using a wireless network

While you are using HP Wireless Presenter-to-Go, you have access to only one wireless network: the infrastructure or ad-hoc network that connects to the projector. If you use a different wireless network to connect to other computers or to the internet, you do not
