Ventilation Requirement
This oscilloscope uses fans 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 a temperature increase which can
damage the instrument. So please keep the instrument well ventilated
during operation and inspect the intake and fan regularly.
