Other Precautions
For proper installation, read this guide carefully and observe the following precautions.
• Don’t place sharp or heavy objects on the DT770.
• Turn off your DT770 and shut down your computer before connecting any cables. Otherwise
you can damage the DT770 or your computer.
• Don’t set the resolution of the DT770 to greater than 1280 × 1024.
• Don’t block the DT770’s ventilation holes. Doing so can cause the DT770 to overheat.
• If you move the DT770, hold it on the sides or the back. Don’t apply pressure to the screen.
• Avoid setting up and using the DT770 in an area with excessive levels of dust, humidity and
smoke or where it’s exposed to direct sunlight, severe temperature changes, heat from other
appliances, water or any other liquid. Operate the DT770 in an environment with a
temperature range between 41°F and 95°F (5°C to 35°C) and with a humidity range of 20% to
80% (non-condensing). However, you can store the DT770 in an environment with a
temperature range of -4°F to 140°F (-20°C to 60°C) and a humidity range of 20% to 80%
(non-condensing).
• Don’t modify the power cord. Handle it carefully and avoid bending it excessively. Don’t place
the power cord in an area where it’s likely to be stepped on or pinched by items placed on or
against it. If you must run a cable over the floor, lay it flat, in a straight line, and secure it to the
floor with tape or a cable management strip of contrasting color.
• Your DT770 comes with a power plug that works with your country’s power outlets. If the
power plug is a three-prong, grounding-type power plug (designed to fit into a grounding-type
power outlet) and you’re unable to insert the plug into the outlet, contact an electrician to
replace the outlet. Don’t modify the power plug.
• If possible, unplug the DT770 before any thunderstorms. However, don’t touch the unit or the
unit’s power plug during a thunderstorm, as there is a risk of electrical shock.
• Unplug the DT770 if you won’t use it for an extended period.
• Don’t hit or drop the DT770 or subject it to intense shock or vibration.
• If the DT770 requires replacement parts, use parts that are specified by SMART Technologies
Inc.
