NOTE: When operating in the expanded temperature range, the performance of the system may be impacted.
NOTE: When operating in the expanded temperature range, ambient temperature warnings may be reported on the LCD
panel and in the System Event Log.
Expanded operating range
• The operating temperature is specified for a maximum altitude of 950 m for expanded operating range.
• Do not perform cold start at 5°C or lower, due to hard drive constraints.
