sically able to do so. The requirements mentioned earlier also

apply to this specialist.

•

Attach the mounting plate A of the LH 46 to a strong horizontal

surface.

– The surface must be able to carry the weight of the loudspeaker

plus the weight of all parts used. Calculate the weight and addi-

torque of (see fi . 15Nm .1)

•

Only adjust and secure the height of the telescopic tube when a

load is not attached:

–

To prevent the inner tube from accidentally slipping out of the

telescopic tube, always hold the inner tube with one hand when

adjusting the height.

– Loosen the hex head screw C which secures the inner tube of the

telescopic tube.

now properly fastened to the LH 46.

•

Use safety wires to additionally protect the loudspeaker and the

mounting hardware against tipping/dropping. The safety wires, rope

terminations and coupling links must comply in their dimensioning

and condition with the regulations and standards of the country in

which they are used and must reliably prevent tipping/dropping of

the attached loudspeaker and mounting hardware.
