  Do not leave the equipment in an unconditioned environment with a storage 
temperature above 60°C (140°F) or below 0°C (32°F), which may damage the 
equipment. 
  The unit should be operated under maximum ambient temperature of
 35°C 
(
95°F). 
 
  Make sure the power voltage is within safety range and has been adjusted 
properly to the value of 100~240V before connecting the equipment to the 
power outlet. 
  Always unplug the AC power cord before installing any add-on card or module 
to the equipment. 
  Always disconnect the AC power cord or uninstall the battery pack or switch off 
the wall socket if the equipment would be left unused for a certain time to 
achieve zero energy consumption. 
 
Never pour liquid into the opening that could damage the equipment or cause an 
electrical shock. 
 
Place the power cord in a way that people are unlikely to step on it.    Do not place 
anything on top of the power cord.
