SAFETY

The lightning ash with arrow head within an equilateral triangle is

intended to alert the user to the presence of uninsulated "dangerous

voltage" within the product's enclosure that may be of su󰀩cient

magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert

the user to the presence of important operating and maintenance

(servicing) instructions in the literature accompanying the appliance.

Please follow all warnings, precautions and maintenance as recommended in this user’s guide.

To avoid electric shock, the unit and its peripherals must be properly grounded (earthed).

Important Safety Instruction

• Do not block any ventilation openings. To ensure reliable operation of the projector and to protect from

over heating, it is recommended to install the projector in a location that does not block ventilation. As an

example, do not place the projector on a crowded co󰀨ee table, sofa, bed, etc. Do not put the projector in

an enclosure such as a book case or a cabinet that restricts air ow.

• To reduce the risk of re and/or electric shock, do not expose the projector to rain or moisture. Do not

install near heat sources such as radiators, heaters, stoves or any other apparatus such as ampliers

that emits heat.

• Do not let objects or liquids enter the projector. They may touch dangerous voltage points and short out

parts that could result in re or electric shock.

• Do not use under the following conditions:

± In extremely hot, cold or humid environments.

(i) Ensure that the ambient room temperature is within 0°C ~ 40°C

(ii) Relative humidity is 10% ~ 80%

± In areas susceptible to excessive dust and dirt.

± Near any appliance generating a strong magnetic eld.

± In direct sunlight.

• Do not use the unit if it has been physically damaged or abused. Physical damage/abuse would be (but

not limited to):

± Unit has been dropped.

± Power supply cord or plug has been damaged.

± Liquid has been spilled on to the projector.

± Projector has been exposed to rain or moisture.

± Something has fallen in the projector or something is loose inside.

• Do not place the projector on an unstable surface. The projector may fall over resulting in injury or the

projector may become damaged.

• Do not block the light coming out of the projector lens when in operation. The light will heat the object

and could melt, cause burns or start a re.

English

• Please do not open or disassemble the projector as this may cause electric shock.

• Do not attempt to service the unit yourself. Opening or removing covers may expose you to dangerous

voltages or other hazards. Please call Optoma before you send the unit for repair.

• See projector enclosure for safety related markings.

• The unit should only be repaired by appropriate service personnel.

• Only use attachments/accessories specied by the manufacturer.

• Do not look into straight into the projector lens during operation. The bright light may harm your eyes.

• Turn o󰀨 and unplug the power plug from the AC outlet before cleaning the product.

• Use a soft dry cloth with mild detergent to clean the display housing. Do not use abrasive cleaners,

waxes or solvents to clean the unit.

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

• Do not setup the projector in places where it might be subjected to vibration or shock.

• Do not touch the lens with bare hands.

• ! WARNING CHEMICAL BURN HAZARD

This product contains a small button battery. If swallowed, this battery can cause severe

internal burns [within 2 hours] and can lead to death.

Keep new and used batteries away from children. If battery compartment will not close

securely, stop using product and keep it away from children.

If you think batteries might have been swallowed or placed inside any part of the body,

seek immediate medical attention.

• Remove battery/batteries from remote control before storage. If the battery/batteries are left in the

remote for long periods, they may leak.

• Do not use or store the projector in places where smoke from oil or cigarettes may be present, as it can

adversely a󰀨ect the quality of the projector performance.

• Use a power strip and or surge protector. As power outages and brown-outs can KILL devices.

Safety Information

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

• Product label(Rating label) on the bottom of the product.

Cleaning the Lens

• Before cleaning the lens, be sure to turn o󰀨 the projector and unplug the power cord to allow it to

completely cool down.

• Use a compressed air tank to remove the dust.

• Use a special cloth for cleaning lens and gently wipe the lens. Do not touch the lens with your ngers.

• Do not use alkaline/acid detergents or volatile solvents such as alcohol for cleaning lens. If the lens is

damaged due to the cleaning process, it is not covered by the warranty.

Warning: Do not use a spray containing ammable gases to remove dust or dirt from the lens. This

may cause a re due to excessive heat inside the projector.

Warning: Do not clean the lens if the projector is warming up as this may cause the lens’ surface lm

to peel o󰀨.

Warning: Do not wipe or tap the lens with a hard object.

Infra-Red (IR) remote control sensor is located on the rear side of the projector. Ensure that the remote control is held

at an angle ±30 degrees perpendicular to the projector’s IR remote control sensor to ensure correct functionality. The

distance between the remote control and the sensor should not be longer than 6 meters (19.7 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 on directly by sunlight or

uorescent lamps.

• Please keep the remote controller at least 2m away from uorescent lamps or it may malfunction.

• If the remote control is close to Inverter-Type uorescent lamps, it might become ine󰀨ective from time

Troubleshooting

If you experience a problem with your projector, please refer to the following information. If a problem persists,

please contact your local reseller or service center.

Image problems

No image appears on-screen

• Ensure all the cables and power connections are correctly and securely connected as described in the

"Installation" section.

• Ensure the pins of connectors are not crooked or broken.

• Ensure that the "Mute" feature is not turned on.

Image is out of focus

• Ensure the distance between projector and the edge of table is less then 120mm to avoid light sensor

detection interference. (For ML1050STi only.)

• Turn the focus lever clockwise or counterclockwise until the image is sharp and legible.

(For ML750i only.) (Please see page 24).

• Make sure the projection screen is between the required distance from the projector.

(Please refer to pages 51~52).

The image is stretched when displaying 16:9 DVD title

• When you play anamorphic DVD or 16:9 DVD, the projector will show the best image in 16: 9 format

on projector side.

• If you play 4:3 format DVD title, please change the format as 4:3 in projector OSD.

• Please setup the display format as 16:9 (wide) aspect ratio type on your DVD player.

Image is too small or too large

• Use the Zoom function or congure the Aspect Ratio setting in the Image menu.

(Please see page 37).

• Move the projector closer to or further from the screen.

Image has slanted sides:

• If possible, reposition the projector so that it is centered on the screen and below the bottom of the

screen.

Image is reversed

• Select "Display  Projection" from the OSD and adjust the projection direction.

(Please see page 39).
