Safety Precautions - General

Please read the following Safety Precautions before you start using the projector.

• Keep this user guide in a safe place for later reference.

• Read all warnings and follow all instructions.

• Allow at least 20“ (50 cm) clearance 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 the projector on an uneven or unstable surface. The projector may fall over, causing personal injury or projector malfunction.

• Do not use if the projector is tilted at an angle of more than 10° degrees left or

right, nor at an angle of more than 15° degrees forwards or backwards.

• Do not look straight at the projector lens during operation. The intense light beam may damage your eyes.

• Always open the lens shutter or remove the lens cap when the projector light source is on.

• Do not block the projection lens with any objects when the projector is under operation as this could cause objects to become heated and deformed or even cause a fire.

• The light source becomes extremely hot during operation. Allow the projector to cool for approximately 45 minutes prior to removing the light source assembly for replacement.

• Do not use light sources beyond the rated light source life. Excessive use of light

sources beyond the rated life could cause them to break on rare occasions.

• Never replace the light source assembly or any electronic component unless the projector is unplugged.

• Do not attempt to disassemble the projector. There are dangerous high voltages inside which may cause death if you should come into contact with live parts.

• When moving the projector, be careful not to drop or bump the projector on anything.

• Do not place any heavy objects on the projector or connection cables.

• Do not stand the projector on end vertically. Doing so may cause the projector to fall over, causing personal injury or projector malfunction.

• Avoid exposing the projector to direct sunlight or other sources of sustained heat. Do not install near any heat sources such as radiators, heat registers, stoves, or other devices (including amplifiers) that may increase the temperature of the projector to dangerous levels.

• Do not place liquids near or on the projector. Liquids spilled into the projector may cause it to fail. If the projector does become wet, disconnect it from the power supply and call your local service center to have the projector serviced.

• When the projector is under operation, you may sense some heated air and odor from its ventilation grill. It is a normal operation and not a defect.

• Do not attempt to circumvent the safety provisions of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide and third blade are provided for your safety. If the plug does not fit into your outlet, obtain an adapter and do not attempt to force the plug into the outlet.

• When connecting to a power outlet, DO NOT remove the grounding prong. Please ensure grounding prongs are NEVER REMOVED.

• Protect the power cord from being treaded upon or pinched, particularly at the plug, and at the point where it emerges from the projector.

• In some countries, the voltage is NOT stable. This projector is designed to operate safely within a voltage between 100 to 240 volts AC, but could fail if power cuts or surges of ±10 volts occur. In areas where voltage may fluctuate or cut out, it is recommended that you connect your projector through a power stabilizer, surge protector, or uninterruptable power supply (UPS).

• If smoke, an abnormal noise, or a strange odor is present, immediately switch

the projector off and call your dealer or ViewSonic®. It is dangerous to continue

using the projector.

• Use only attachments/accessories specified by the manufacturer.

• Disconnect the power cord from the AC outlet if the projector is not being used for a long period of time.

• Refer all servicing to qualified service personnel.

CAUTION: Possibly hazardous optical radiation is emitted from this product. As

with any bright light source, do not stare into the beam, RG2 IEC 62471-5:2015.

Safety Precautions - Ceiling Mounting

Please read the following Safety Precautions before you start using the projector.

If you intend to mount the projector on the ceiling, we strongly recommend

that you use a proper fitting projector ceiling mount kit and that you ensure it is

securely and safely installed.

If you use an inappropriate projector ceiling mount kit, there is a safety risk that the

projector may fall from the ceiling due to an improper attachment through the use of the wrong gauge or length screws.

You can purchase a projector ceiling mount kit from the place you purchased your

projector. We recommend that you also purchase a separate security cable and

attach it securely to both the anti-theft lock slot on the projector and the base of the ceiling mount bracket. This will perform the secondary role of restraining the projector should its attachment to the mounting bracket become loose.

Laser Caution

This product belongs to CLASS I laser product and complies with IEC 60825-1:2014.

Above laser cautions are located on the bottom of this apparatus.

(for all regions except China)

• Noce is given to supervise children and to never allow them to stare into the projector beam at any distance from the projector.

• Noce is given to use cauon when using the remote control for starng the

projector while in front of the projecon lens.

• Noce is given to the user to avoid the use of opcal aids such as binoculars or telescopes inside the beam.

Remote Control Effective Range

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

Approx. 30°

the sensor(s) should not exceed 8 m (26 ft.)

NOTE:

Refer to the illustration for the location of the infrared (IR) remote control sensor(s).

Replacing the Remote Control Batteries

1. Remove the battery cover from the rear of the remote control by pressing the

finger grip and sliding it down.

2. Remove any existing batteries (if necessary) and install two AAA batteries.

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.

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.

• Dispose of the used batteries according to the manufacturer’s instructions and

local environment regulations for your region.

• If the batteries are drained or if you will not be using the remote control for an

extended period of time, remove the batteries to avoid damage to the remote control.

Initial Setup

This section provides detailed instructions for setting up your projector.

Choosing a Location

Personal preference and room layout will decide the installation location. Consider the following:
