2.1 Environment Conditions
This unit operates normally in a surrounding temperature of 0 to 50 ˚C. To maintain this unit in top-running form, avoid
using it in the following locations :
• Areas prone to violent shaking
• Areas exposed to high humidity and large quantities of dust
• Areas exposed to direct sunlight
• Areas that may be exposed to volatile gases
In addition to the above conditions, we recommend you use the unit at room temperature or below and in a location with
few power fluctuations to maintain stable operation for an extended period of time.
CAUTION
Using this unit for an extended period of time where the temperature is 0 ˚C or
less and then using it under normal temperatures can cause condensation that
shorts circuits, resulting in damage to the unit. To prevent this from happen-
ing, allow the condensation to thoroughly dry before turning on power to the
unit.
