Remote Control - Receiver Range

IR Receiver Location

To ensure proper function of the remote control follow the steps below:

  1. The remote control must be held at an angle within 30° perpendicular to the projector’s IR remote control sensor(s).
  2. The distance between the remote control and the sensor(s) should not exceed 8 m (26 ft.).
    3. NOTE: Refer to the illustration for the location of the infrared (IR) remote control sensor(s).

Replacing the Batteries

  1. Remove the battery cover from the bottom of the remote control by pressing the finger grip and sliding it across.
  2. Remove any existing batteries (if necessary) and install two AAA batteries.
    3. NOTE: Observe the battery’s polarities as indicated.
  3. Replace the battery cover by aligning it with the base and pushing it back into position.
    4. NOTE:
    • Avoid leaving the remote control and batteries in excessive heat or a humid environment.
    • Replace only with the same or equivalent type recommended by the battery manufacturer.
    • If the battery is drained or if you will not be using the remote control for an extended period of time, remove the battery to avoid damage to the remote control.
    • Dispose of used batteries according to the manufacturer’s instructions and local environment regulations for your region.

Read these instructions carefully, keep them in a safe place, and follow all warnings and instructions.

General Safety Precautions

  • During normal operation, warm air and a slight odor may come from the ventilation.
  • When using the projector, avoid direct exposure to the projector’s exhaust vent.
  • Keep the remote control or loose batteries away from children or pets.

Installation

  • Follow the manufacturer's recommended installation guidelines to ensure safe and optimal operation.
  • Leave at least 50 cm (20 in.) of open space around the projector to ensure proper ventilation.
  • Place the projector in a well-ventilated area. Do not place anything on the projector that prevents heat dissipation.
  • Do not place any heavy objects on the projector or cables.
  • Do not place the projector in an unstable location. The projector may fall, resulting in injury or damage.
  • Do not stand the projector upright. The projector may fall, resulting in injury or damage.
  • Do not use the projector near open flames, sparks, or hot surfaces.
  • Do not use the projector near water or in humid conditions and avoid exposing it to rain or moisture.
  • Do not expose the projector to direct sunlight or other sources of sustained heat.
  • Always route and manage cables connected to your projector to prevent tripping, pulling, or grabbing.
  • The projector is designed to operate at 120/240V AC. Unstable voltages can harm the projector. Use a power stabilizer, surge protector, or UPS in areas with frequent power cuts or surges.

Power Cord Safety

  • Do not compress the power cord, particularly at the plug and at the point where it connects to the projector.
  • Do not use the projector if the power cord or plug is damaged.
  • The power cord is designed with a grounding prong to ensure safe operation. Do not remove or damage the grounding prong.
  • Only use the original power cord and do not use damaged or modified cords.
  • Unplug the projector when it will be unused for long periods of time.

Handling

  • When moving the projector, handle it with care to avoid damage or injury.
  • Only use attachments and accessories specifically designed and approved by the manufacturer to ensure compatibility and safety.

Troubleshooting

  • If smoke appears, an abnormal noise, or a strange odor is present, immediately turn the projector off and contact your reseller or ViewSonic. It is dangerous to continue using the projector.
  • Refer all servicing to qualified service personnel.
  • Do not disassemble the projector. It contains electrical components that can cause shock.

Lens Safety

  • When using the projector, avoid looking directly at the projector lens.
  • Avoid blocking the projection lens when using the projector, as this can cause objects to overheat and potentially ignite.

Lamp Safety

  • Unplug the projector before replacing the lamp assembly or component.
  • Allow the projector to cool for approximately 45 minutes before replacing the lamp or performing basic maintenance.
