: Noise level is measured when the economy control switch is turned to “ON”.
LWA shows the sound power level under the ISO3744 satisfied test conditions.
The noise level in “dB (A) / 7 m” is the arithmetic mean value in four directions measured 7
meters away from each side of the generator.
The noise level may vary in different environments.
