environment in which you are using the computer.

• Acetic acid, 10% in water
• Ethyl alchohol, 10% in water

• 5% to no more than 10% bleach or sodium hypochlorite in water
Avoid these cleaning agents and all products that contain these agents:
• Hydrogenated hydrocarbons

• Ammonia solutions
• Ethers
• Carbolic acid
• Methyl or isopropyl alcohol
• Methyl ethyl ketone (MEK)
• Heavy detergents
• Alkaline solutions

1 Press the Power button and choose to suspend the computer.
2 Dip a clean, soft, dry cloth towel in the cleaning solution and wring
out the excess.
3 Wipe off the imager window, camera lens, and flash area. Do not
allow any abrasive material to touch these surfaces.
There are no user-serviceable parts inside the 70 Series computer.

damage to the internal components.
