is 45—80%.
Keep it as far as possible away from the strong magnetic or
electrical fields or any electrical device that may generate
high-frequency fields.
Set the unit up in an area that is free of dust, corrosive gases
and strong vibrations.
Remove any obstructions or materials that could hinder the flow
of air under and around the instrument.
The power requirement is 110±11V/60±1Hz or 220±22V/50±1Hz.
Use the appropriate power cord and plug into a grounded outlet.
If the local voltage is not stable, a voltage regulator is required.
Be away from direct sunlight.
