For Proper Operation

Observe the following notes for successful operation of US320f. Ignoring these notes can cause malfunction or failure of
US320f.
 When you have just turned off US320f, wait at least 10 seconds before turning it back on. If US320f is connected to
an uninterruptible power supply (UPS), set a delay of at least 10 seconds in the power-on schedule.
 Turn off the power of US320f and unplug the power cord from the outlet before relocating US320f.
 Clean US320f on a regular basis. Regular cleaning proactively prevents various failures.
 Lightning may cause a momentary voltage drop. To prevent this problem, it is recommended to use an
uninterruptible power supply (UPS) unit.
 It is recommended that US320f should be stored in a place where a stable room temperature is able to be
maintained. It is preferable to store US320f under conditions of temperature: –10°C to 55°C (14°F to 131°F),
humidity: 10% to 95% (non-condensing).
 Turn off cellular phones or pagers around US320f. Radio interference may cause malfunction of US320f.
 Observe the following notes on using and connecting an interface cable.
– Do not use a damaged cable.
– Do not step on the cable.
– Do not place any object on the cable.
– Do not use US320f with loose cable connections.
 If US320f or the option devices (add-ons) connected inside US320f are moved suddenly from a cold environment to a
warm environment, condensation might form inside US320f or its add-ons, causing malfunction or damage if
US320f is used in this state. To protect your important data and assets, be sure to consider the environment
carefully before using US320f.
 Make sure that all add-ons and peripherals are able to be attached or connected to US320f. Note, however, that
even if add-ons or peripherals can be physically attached or connected, they might damage US320f if they do not
work properly.
 We recommend only using official NEC add-ons. Add-ons such memory sticks or hard disk drives from other
companies might be able to be used with US320f, but if these add-ons cause US320f to fail or become damaged,
NEC will not cover the cost of repair, even if the damage occurs within the warranty period.
