See also the “Care andMaintenance” chapter on page 24.For information on carrying the speaker using the two lateral handles, refer to the Transportchapter on page 25.3.2 Instructions for Speaker PlacementWarningSpeakers tipping or falling over impose a deadly risk for people standing near-by!Always consider potential risks when placing the speakers and perform all appropriate stepsrequired for safe operation.Special attention is required when placing the speaker near a stage edge, on a speaker-stand,or at an elevated place.Note that the speaker can start moving due to vibrations, in particular, when placed verticallyon the 3 sliding blocks. These sliding blocks are mainly provided for transport purposes.Therefore, because the speaker is compact and lightweight, sudden lateral forces such asgusts, bumps, or shocks may affect the speaker’s stability, resulting in falling over. Be sure toavoid these, in particular, when the speaker has been placed vertically.When placing the speaker on a speaker stand, be sure to observe the detailed information inthe 'Using a Speaker Stand' chapter on page 11.At all times, ensure that the speaker cannot fall down or tip over.When assessing potential risks, also keep the speaker cable in mind. Run the cables in a waythat nobody can trip over them. In addition to the main connector panel at the bottom, theK&F SCENA 12 speaker provides extra SpeakOn ports on the side panels. Using those lateralports increases the risk of tripping.!
