To turn on the power again, push the power key once again. 27 [Selecting the reference level detecting accuracy] Push the detection accuracy selection switch to select the needed detection accuracy. High accuracy detection: To be selected for detecting the reference level with accuracy. Low accuracy detection: To be selected if high accuracy is not needed or when stable reference level cannot be obtained due to slight vibration at job site. High accuracy Low accuracy NOTE: · For the detection accuracy to be selected, check with the mark in the liquid crystal display (see the figure on the above). · The detection accuracy alternates each time the detection accuracy selection switch is pressed. · High detection accuracy is initiated when the power turns on.
