This section describes how to clean the instrument.
To protect yourself from electrical shock, be sure to unplug the power
cable from the outlet before cleaning the instrument.
Never clean the internal components of the instrument.
Cleaning an LCD
Use one of the following methods to clean the display surface regularly.
• For normal cleaning, rub the surface gently with a dry, soft cloth.
• When stains are difficult to remove, gently wipe the surface with
cloth damped with a small amount of ethanol or isopropyl alcohol.
You can clean the standard type LCD (no touch screen function) with
a cloth dipped in water and then wrung tightly.
• Do not use chemicals other than ethanol and isopropyl alcohol
to wet the cleaning cloth. To clean the touch screen LCD, do not
wet the cloth with water.
Maintenance of Test Ports and Other Connectors/Ports
Test ports on the front panel of the E5071C are fitted with N Type
connectors (f). Stains or other damage to these connectors would
significantly affect the accuracy in measurements in the RF range. Always
pay attention to the following precautions.
• Always keep the connectors free from stains and dust.
• Do not touch the contact surface on the connectors.
• Do not plug damaged or scratched connectors into the test ports.
• Use compressed air for cleaning connectors. Do not use abrasives
under any circumstance.
The above precautions must also be observed in maintaining connectors
and ports other than these test ports.
Cleaning Parts Other than the LCD, Test Ports, and Other Connectors/Ports
To remove stains on parts other than the LCD, test ports, and other
connectors/ports of the instrument, wipe them gently with a soft cloth that
is dry or wetted with a small amount of water and wrung tightly.
