HP (Hewlett-Packard) L1619A ユーザーズマニュアル

This section describes how to upgrade the projector’s firmware.

■

HP might periodically release updated versions of the projector firmware to enhance 
the projector performance. Firmware versions are shown in the on-screen menu at 
Help > About this projector and in the Web interface on the Home tab. Check for 
updated versions at http://www.hp.com/go/proj_firmware.

If you have an attachment module installed, update the firmware using a Web 
connection. If you need to update only the projector firmware, you can use the USB 
method; however, this does not update the module.

1. Be sure the projector is connected to the local network. If you cannot connect to it, 

see the information at the end of these steps.

2. Determine the wired IP address of the projector. See “To find the projector’s 

address” on page 47 for more information.

3. Turn off the projector and allow it to cool.

4. Unplug the M1 cable from the projector, if it is connected.

5. On a networked computer, open Internet Explorer or Netscape Navigator, enter 

the wired IP address of the projector in the URL bar, and press the Enter key.

6. Click the Management tab, and on the left side of the screen, select Firmware 

Upgrade.

7. Click the link for finding upgrade files on the Web, then download the latest 

upgrade file intended for a Web upgrade.

8. Return to the projector Firmware Upgrade page and click Browse. Then select 

the file you downloaded.

9. Click the upgrade button to start the upgrade process. Follow the on-screen 

instructions. Do not interrupt the process until it finishes.
