CAUTION The display screen should be cleaned with an Isopropyl Alcohol based cleaner and a
soft lint-free cotton cloth. The E7495A/B display has a polycarbonate cover with an
anti-reflective coating, which can be damaged if not cleaned properly. The
anti-reflective coating is a surface treatment and can be scratched if wiped with an
abrasive material. Use only soft lint-free cotton cloth and Isopropyl Alcohol to clean
the display.
When selecting a cleaner make sure it does not contain any Ammonia.

things as carrier frequency, reference level, and marker positions.
