4.0 BENCHMARKING
DURING THE WORK DAY, PERIODICALLY CHECK YOUR INITIAL
SETUP TO ENSURE THAT THE LASER REFERENCE HAS NOT
MOVED.
ESTABLISH, AT A SUITABLE DISTANCE (FURTHEST POSSIBLE), A
BENCHMARK (REFERENCE) ON A STABLE SURFACE (I.E. TREE,
BUILDING). PERIODICALLY DURING THE WORK DAY, CHECK THE
BENCHMARK TO ENSURE THAT YOUR SETUP HAS NOT MOVED.
4.1 PROCEDURES FOR CEILING GRID APPLICATIONS (LMH 600 ONLY).
1. ATTACH THE LMH SERIES TO THE OPTIONAL WALLMOUNT
BRACKET. BE SURE THE CONTROL BUTTONS ARE FACING
OUTWARD. TIGHTENING THE LOCKING SCREW WILL SECURE THE
UNIT TO THE BRACKET.
2. AFTER INSTALLING THE FIRST PIECE OF CEILING TRIM, ATTACH
THE WALLMOUNT TO IT. BE SURE THE WALLMOUNT IS SECURE
TO THE TRIM.
3. PRESS THE POWER BUTTON. IF THE OUT-OF-LEVEL INDICATOR
IS BLINKING, PRESS THE MAUNAL GRADE BUTTON TO PUT THE
UNIT INTO AUTOMATIC MODE. ALLOW THE UNIT TO SELF-LEVEL.
4. ADJUST THE DISTANCE OF THE UNIT FROM THE GRID,
TYPICALLY 1.5 INCH (38MM) BELOW THE GRID. LOOSEN THE
ADJUSTMENT SCREW AND SLIDE THE UNIT UP/DOWN ON THE
WALL MOUNT. WHEN THE DESIRED HEIGHT HAS BEEN REACHED,
TIGHTEN THE ADJUSTMENT SCREW TO SECURE THE UNIT.
5. INSTALL THE CEILING GRID. ATTACH THE MAGNETIC LASER
TARGET TO THE CEILING TRIM BEING INSTALLED. ADJUST THE
HEIGHT OF THE TRIM UNTIL THE LASER BEAM STRIKES THE
TARGET.
NOTE: PLACING THE UNIT INTO SCAN MODE WILL MAKE
INSTALLATION EASIER AND MORE EFFICIENT.
TO PLACE THE UNIT INTO SCAN MODE, PRESS THE SCAN MODE
BUTTON UNTIL THE ROTATING LASER HEAD STOPS. PRESS AND
HOLD EITHER CLOCK-WISE OR COUNTERCLOCK-WISE HEAD
