Ventilation Requirement 
 
This oscilloscope uses fan to force cooling. Please make sure that the air intake and 
exhaust areas are free from obstructions and have free air. When using the 
oscilloscope in a bench-top or rack setting, provide at least 10 cm clearance beside, 
above and behind the instrument for adequate ventilation. 
 
 
WARNING  
Inadequate ventilation may cause temperature increase which would 
damage the instrument. So please keep the instrument well ventilated 
during operation and inspect the intake and fan regularly.
