equipment needs to be taken into consideration.
• The system clock and the like inside the equipment always operate by using a backup battery
even when the power is off. Therefore, if you store the equipment at a temperature outside
the operating temperature range, you may need to reconfigure system BIOS settings
including the clock settings, when you start using the equipment again. When you
reconfigure system BIOS settings, follow the instructions in "4.2 BIOS Setup".
