Safety Precautions
These precautions help protect you and your MR2600.
 Do not put the MR2600 or its power cube in water, since this is a
shock hazard.
 Do not use the MR2600 outdoors if that exposes the router to rain,
snow, ice, excessive moisture, extreme temperatures, or other
extreme conditions.
 Your MR2600 should be operated in an environment that's between
32 and 104° Fahrenheit (0 to 40° Centigrade).
 Your MR2600 should not be in a confined space. There should be
room for air flow around the top, front, and sides of the MR2600.
 Make sure to use your MR2600's power cube and a compatible
electrical outlet.
