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 an 5 mn
period to allow the loudspeaker components to stabilize during the very first minutes of usage.
Inspect the speaker system periodically.
