Precautions for Safe Use
Installation environment
Meet the installation environment requirements for the system equipment shown
in Chapter 1. If you use the equipment in the environment with temperatures
higher than the permissible temperature, increase in internal temperature can
cause a failure in equipment.
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
Before adding or connecting peripheral devices to the equipment, remove all
power plugs from the outlets and disconnect all cables from the equipment unless
otherwise instructed. 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.
Consumables
Use only specified consumables. Using consumables other than those specified
would not only reduce reliability of the product but also cause a failure, electric
shock, or fire.
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. If this happens, do the following:

Place the equipment as far away as possible from the TV or radio.

Change the antenna orientation of the TV or radio.

Plug these cables into separate electrical outlets.
