Moving between two locations with a temperature differential
When you move the equipment from one location to another, a significant
temperature gap between the two locations may cause condensation on
the surface or inside the equipment. Operating the equipment with
condensation inside can cause a failure in equipment. Leave the
equipment at the new location for several hours until the equipment
temperature conforms to that of the new environment before you start
using it. When you move the equipment from an environment with
temperature 5°C to that with 25°C, for example, leave it for about two
hours.
Adding and connecting to peripheral devices
Use only peripheral devices which are explicitly listed as supported in the
manual, and always follow the instructions in the manual. Using devices
other than those mentioned above would cause a failure in peripheral
devices and equipment due to the difference in connection specifications.
Radio interference
When you install the equipment next to another electronic device, the
radio waves may interfere with each other. In particular, a television set
or a radio in the vicinity may make a noise.
Magnetism generator
Do not place a device that generates strong magnetism, such as a
magnet or a speaker, near the equipment. Doing so can cause a system
unit failure.
Handling hard disks
A hard disk is a precision instrument. Handle it carefully when you use it.
Inappropriate handling could result in hard disk failure.
