BASIC PRECAUTIONS
Do not open the speaker system or attempt to disassemble the internal parts or modify them in any way. The speaker system
contains no user-serviceable parts. If it should appear to be malfunctioning or damaged, discontinue use immediately and have
it inspected by qualified NEXO service personnel.
Water exposure: Do not expose the speaker system to direct rain, do not use it near water or in wet conditions. Do not place
containers with liquid on speaker system as they might spill into openings. If any liquid such as water seeps into the speaker
system, have it inspected by qualified NEXO personnel.
Sun exposure: Do not expose the speaker system to direct sun.
Operating temperature with temperate climate: 0°C to +40°C (-20°C to +60°C for storage).
SYSTEM DEPLOYMENT SAFETY RULES
Read User Manual before deployment . Before use of enclosed speaker system, please ensure that anyone
involved in system deployment understands the rigging
– stacking – pole mounting safety rules as described
in the speaker system User Manual. Failure to do this exposes people to potential injury or death.
Please check the web site nexo-sa.com for the latest update.
Always consult qualified NEXO personnel if the device installation requires construction work and make sure to observe the
following precautions:
Mounting precautions
- choose mounting hardware and an installation location that can support 4 times the weight of the speaker system;
- do not use speaker system handles for suspended installation;
- do not expose speaker system to excessive dust or vibration, or extreme cold or heat to prevent possibility of component
damage;
- do not place the speaker system in an unstable position from which it might fall accidentally;
- if speaker systems use a stand, ensure that stand specifications are adapted, and that stand height does not exceed
1.40m/55”; never move the stand while the speaker is in position.
- in case of wind greater than 8 on Beaufort scale (72km/h
– 45mph), a touring system has to be landed or an additional
securing has to be implemented.
- for fixed installations, wind loading has to be taken into account in accordance to the national standards.
Connection and powering precautions
- remove all connected cables before moving the speaker system;
- turn off AC power of all power amplifier units before connecting the speaker system;
- when turning on the AC power to the audio system, always turn on the power amplifier last; when turning the AC power off,
always turn off the power amplifier first;
- when used in cold conditions, a gradual power ramp up should be applied to the system on a 5 mn period to allow the
loudspeaker components to stabilize during the very first minutes of usage.
Inspect the speaker system periodically.
