- Plug the other end of the power cord into a grounded electrical outlet.
2.3 Connecting Video Sources
The projector offers multiple connectivity options. Refer to the rear panel diagram for port locations.
- HDMI: Connect an HDMI cable from your video source (e.g., laptop, Blu-ray player) to the HDMI port on the projector. The projector supports HDMI 1.4a.
- VGA: Connect a VGA cable from your computer to one of the VGA In ports (VGA In 1 or VGA In 2).
- Composite Video: Use an RCA cable to connect to the Composite Video port for standard definition video sources.
- Network (RJ-45): For network control and monitoring, connect an Ethernet cable to the RJ-45 port.
- RS232 (DB-9pin): For serial control, connect a DB-9pin cable to the RS232 port.

3. Operating Instructions
3.1 Powering On/Off
- Power On: Press the Power button on the projector's control panel or the remote control. The power indicator light will illuminate.
- Power Off: Press the Power button again. A confirmation message may appear; press Power again to confirm shutdown. Allow the projector to cool down completely before unplugging it.
3.2 Input Source Selection
To switch between connected video sources, use the "Source" or "Input" button on the remote control or the projector's control panel. Cycle through the available inputs (HDMI, VGA1, VGA2, Video) until your desired source is displayed.
3.3 Image Adjustment
- Focus: Adjust the focus ring on the projector lens until the image is sharp and clear.
- Keystone Correction: If the image appears trapezoidal, use the keystone correction function (usually found in the projector's OSD menu or via dedicated buttons on the remote) to square the image.
- Aspect Ratio: The projector has a native aspect ratio of 16:10 (WXGA). You can adjust the aspect ratio settings in the menu to match your content (e.g., 4:3, 16:9) if necessary.
3.4 Supported Video Modes
The Promethean UST-P1 supports various video modes, including 720p, 1080i, 1035i, 575i, 576i, 480p, and 480i.
4. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your projector.
4.1 Cleaning the Projector
- Exterior: Use a soft, lint-free cloth slightly dampened with water to clean the projector's casing. Avoid abrasive cleaners or solvents.
- Lens: Gently wipe the projector lens with a lens cleaning cloth or lens paper. Do not use abrasive materials or excessive force, as this can scratch the lens.
- Air Vents: Periodically check and clean the air vents to prevent dust buildup, which can impede airflow and cause overheating. Use a soft brush or compressed air to remove dust.
4.2 Lamp Replacement
The Promethean UST-P1 is a lamp-based projector. The lamp has a finite lifespan and will eventually need replacement. The projector will typically display a warning message when the lamp is nearing the end of its life. Refer to the projector's on-screen display (OSD) menu for lamp hour information.
Caution: Lamp replacement should only be performed when the projector is completely cool and unplugged from the power source. Consult a qualified technician if you are unsure about the replacement procedure.
