SETUP AND INSTALLATION

Installing the projector

Your projector is designed to be installed in one of four possible positions.

Your room layout or personal preference will dictate which installation location you select. Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location and distance between the projector and the rest of your equipment.

Projector should be placed flat on a surface and 90 degrees / perpendicular to the screen.

Note: The further away the projector is placed from the screen the projected image size increases and vertical offset also increases proportionally.

IMPORTANT! Do not operate the projector in any orientation other that table top or ceiling mount. The projector should be horizontal and not tilted either forwards/backwards or left/right. Any other orientation will invalidate the warranty and may shorten the lifetime of the projector lamp or the projector itself.

For none standard installation advise please contact Optoma.

  • To adjust the image position, turn the lens shift dial clockwise or counterclockwise to adjust the position of the projected image vertically
• To adjust the focus, turn the  focus ring clockwise or counterclockwise until the image is sharp and legible.

Note: The projector will focus at a distance of 1.2m to 8.1m.

Remote setup

Installing / replacing the battery

1. Use a coin to turn the battery cover counterclockwise until the cover opens.
2. Install new battery into the compartment.
   Remove the old battery and install new one (CR2032). Ensure that the side with a “+” is facing up.
3. Put the cover back. Then use a coin to turn the battery cover clockwise to lock it in place.

CAUTION:

To ensure safe operation, please observe the following precautions:

• Use CR2032 type battery.
• Avoid contact with water or liquid.
• Do not expose the remote control to moisture or heat.
• Do not drop the remote control.
• If the battery has leaked in the remote control, carefully wipe the case clean and install new battery. Risk of an explosion if battery is replaced by an incorrect type.
• Dispose of used battery according to the instructions.

Effective range

Infra-Red (IR) remote control sensor is located on top of the projector. Ensure to hold the remote control at an angle within 30° (horizontally) or 20° (vertically) perpendicular to the projector’s IR remote control sensor to function correctly. The distance between the remote control and the sensor should not be longer than 7 meters (~22 feet).

Note: When pointing the remote control directly (0 degrees angle) on the IR sensor, the distance between the remote control and the sensor should not be longer than 10 meters (~32 feet).

• Make sure that there are no obstacles between the remote control and the IR sensor on the projector that might obstruct the infra-red beam.
• Make sure the IR transmitter of the remote control is not being shined by sunlight or fluorescent lamps directly.
• Please keep the remote controller away from fluorescent lamps for over 2 meters or the remote controller might become malfunction.
• If the remote control is close to Inverter-Type fluorescent lamps, it might become ineffective from time to time.
• If the remote control and the projector are within a very short distance, the remote control might become ineffective.
• When you aim at the screen, the effective distance is less than 7 meters from the remote control to the screen and reflecting the IR beams back to the projector. However, the effective range might change according to screens.
