*If the operating level is set to the stable operation range, the E3G will operate with the
highest reliability and without being influenced by temperature change, voltage fluctuation,
dust, or setting change. If the operating level cannot be set to the stable operation range,
pay close attention to environmental changes while operating the E3G.
