Do not use or store the document camera outdoors for an extended length of time, or where it may be exposed to rain, water, or excessive humidity. Fire or electric shock may result.
Do not use or store the document camera where it may be exposed to smoke, steam, corrosive gases, or excessive dust. Fire or electric shock may result.
Caution
Do not set up the document camera near high-voltage electrical wires or sources of magnetic fields. This may interfere with correct operation.
Operate in the proper environmental conditions. s "General Specifications" p.57
Do not place or store the document camera where it is accessible to small children. It may drop or tip over, causing personal injury.
Do not place the document camera where it may be exposed to vibration or shock.
Electrical Precautions
Warning
Never open any covers on the document camera except as specifically explained in this User's Guide. Never attempt to disassemble or modify the document camera. Refer all repairs to qualified service technicians.
Unplug the document camera from the outlet and contact your local dealer or Epson for help under the following conditions:
If smoke, strange odors, or strange noises come from the device
If liquid or foreign objects get inside the device
If the device has been dropped or the housing has been damaged
Continuing to use under these conditions may result in fire or electric shock.
Do not attempt to use any adapter other than the AC adapter and power cord included with the device. Using an improper adapter may cause damage, overheating, fire, or electric shock.
Be sure to use the AC adapter with the proper voltage indicated in this guide. Use of a different power source may result in fire or electric shock.
If the AC adapter, power cord, or document camera is damaged, turn the power off, unplug the AC adapter from the electrical outlet, and contact your local dealer or Epson for help.
Do not touch the device, the AC adapter, or the plug with wet hands. Otherwise, you may receive an electric shock.
Do not use a power cord that is damaged. This may result in fire or electric shock. Take the following precautions when handling the power cord:
Do not modify the power cord.
Do not place heavy objects on the power cord.
Do not bend, twist or pull the power cord excessively.
Keep the power cord away from hot electrical appliances.
Take the following precautions when handling the plug. Failure to comply with these precautions could result in fire or electric shock.
Do not overload wall outlets, extension cables, or power strips.
Do not insert the plug into a dusty outlet.
Insert the plug firmly into the outlet.
Do not pull the power cord when disconnecting the plug; always be sure to hold the plug when disconnecting it.
Do not touch the plug during an electrical storm. Otherwise, you may receive an electric shock.
Caution
Turn off the document camera and unplug it after use.
Make sure the power is turned off, the plug is disconnected from the outlet, and all cables are disconnected before moving the document camera.
If a malfunction occurs due to static electricity, thunder, and so on, the product begins recovery operations. During recovery operations, do not touch any switches on the product.
Installation Precautions
Warning
Do not use adhesives to prevent the screws from loosening and do not use oils or lubricants. This may cause the document camera housing to crack and could cause serious injury.
Caution
Do not place the document camera in an unstable location, such as on a shaky table or slanted surface. The document camera may drop or tip over, causing personal injury. If you use a table, cart, or stand, make sure it is stable and will not fall over.
When using the mounting points under the document camera to secure it to a table, cart, or stand, fasten the two bolts securely but do not overtighten them. Do not use adhesives.
Do not place the document camera in a poorly ventilated place where heat can accumulate.
Do not place the document camera on a carpet, blanket, and so on, or cover it during use.
Do not install the document camera in a hot location, such as near a heater.
Route cables so that they are not a tripping hazard. Otherwise, they could trip someone and cause a fall or injury.
Cleaning Precautions
Warning
Use a dry cloth (or, for stubborn stains, a moist cloth that has been wrung dry) for cleaning. Do not use liquid, aerosol cleaners, or solvents such as alcohol, thinner or benzine.
Do not place any containers of liquid on top of or near the document camera.
Do not spill liquid or spray fine mist into the document camera. Liquids entering the document camera may cause malfunction, fire, or electric shock. If you spilled liquid, turn the power off, unplug the AC adapter from the electrical outlet, and contact your local distributor. Using the damaged device may cause fire or electric shock.
Never allow objects of any kind to enter any openings in the document camera. Do not leave objects, especially flammable objects, near the document camera. Doing so may result in fire or electric shock.
Caution
Unplug the AC adapter from the outlet before cleaning to prevent electric shock.
Usage Precautions
Caution
Do not look into the lens when the LED illumination lamp is on. The bright light can damage your eyes.
Do not use excessive force when adjusting the document camera. The document camera may be broken, resulting in personal injury.
Do not place heavy objects on document camera. Otherwise, it may be damaged.
Do not try to press the arm flat or fold it backwards. Otherwise, it may be damaged.
Battery Precautions
Warning
Incorrect battery usage may cause batteries to rupture and leak battery fluid, which could result in fire, injury, or corrosion of the remote control.
If battery fluid gets in your eyes, do not rub your eyes. Wash them well with clean water and contact a doctor immediately.
If battery fluid enters your mouth, rinse immediately with plenty of water and contact a doctor immediately.
If battery fluid comes in contact with your skin or clothes, wash with water to prevent possible skin damage.
Keep batteries out of the reach of children; they are choking hazards and are very dangerous if swallowed.
Prepare two replacement manganese or alkaline AA batteries. Do not install batteries of different types, or mix new and old batteries.
Insert batteries so that the polarities (+ and -) are correct. Not doing so may cause leakage, overheating, or explosion.
Be sure to replace both batteries with new ones of the same type. Not doing so may cause leakage, overheating, or explosion.
Remove the batteries if you will not be using the remote control for a long period of time. When a battery runs down, take it out of the remote control immediately. If a used-up battery is left inside for a long time, gas emitted from the battery may cause leakage, overheating, explosion, or damage to the remote control.
Do not expose batteries to heat, flame, or water.
Dispose of used batteries according to local regulations.
