B. Detecting the horizontal laser signal:

Put the detector in a vertical position
(observe the horizontal indicating bubble)
with the detecting window facing the
unit to receive the laser signal. A down-
ward arrow shown on LCD plus a lit red lamp means the laser
signal is below the detector. An Upward arrow plus a yellow lit
lamp means the laser signal is above the detector. A middle sign
plus a lit green lamp means the laser signal is centered.

Note: When the laser signal moves towards
the center position, the displayed upward
or downward arrows will decrease segment
by segment along the direction towards the
middle, until the centered single line appears.

C. Detecting the vertical laser signal. Put the detector

in a horizontal position (observe the vertical indi-
cating bubble) with the face including an indica-
tor lamp upwards. Have the detecting window
face the unit to receive the vertical laser signal.
Leftward arrow shown on LCD plus a lit red lamp
means the laser signal is on the left side. A v cen-
tered sign with a lit green lamp means the laser
signal is on the middle position. A rightward arrow
plus a lit yellow lamp means the laser signal is on the right side.

D. Press the Power on/off key in the power-on state, and the
