Page 10: Safety Considerations
EM Acoustics is in no way liable for any loss, damage or injury caused by such practice. Do not modify or alter the HALO Arena hardware or accessories, nor use them in any way other than that described in this manual. Rigging components supplied as part of the HALO Arena system are in no way interchangeable and should not be used as such. -
Page 11: Secondary Safeties
Safety Inspections Carefully inspect all flying system components prior to use for defects or signs of damage prior to assembling a HALO Arena array. If any components damaged or you suspect them to be damaged, DO NOT USE THEM. Regular scheduled tests – which are much more rigorous than visual inspections – of all rigging components must also be carried out. -
Page 12: Simulation
For safety and acoustic reasons, it is advised that users familiarize themselves with Ease Focus 3. Along with providing the user with accurate simulations for setting up HALO Arena, it also provides importing safety information with regards to load limits. -
