1-3. Installation Requirements
1-3-1. Environment
Temperature range: 17 to 28 degrees C [63 to 82 degrees F]
Humidity range: 30 to 85 %Rh - no condensation
Ventilation: Room air should turn over at least three times per hour
Avoid placing the machine where it will be exposed to corrosive gases.9
Place the machine on a strong and level base.
Place the machine where it will be:
• Not subject to direct sunlight
• Not subject to strong vibration
• Condensation free
• Away from other electronic equipment, to avoid interference
• Away from heaters and air conditioners, to avoid sudden temperature changes.
