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.
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.
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.
Read this manual before servicing the product.
Always consult qualified NEXO personnel if the device installation requires construction work and make sure to
observe the following precautions:
- Choose mounting hardware and an installation location that can support 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.
Only use NEXO approved spare parts.
Service the speaker system periodically, at least once a year.

HIGH SOUND PRESSURE LEVELS
Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in
susceptibility to noise-induced hearing loss but nearly everyone will lose some hearing if exposed to sufficiently
intense noise for a sufficient period of time. The U.S. Government’s Occupational and Health Administration (OSHA)
has specified the following permissible noise level exposures: Sound Duration Per
Day In Hours
Sound Level dBA, Slow Response

2.1 Safety first
The Rigging System is a professional precision tool set, and should be handled with extreme care. Only persons who are fully
conversant with the operation of the Rigging System and provided with suitable safety equipment should deploy it. Misuse of
Rigging System could lead to dangerous consequences.
Used and maintained correctly, the Rigging System will give many years of reliable service in portable systems.
2.2 Mechanical maintenance of the system
GEO M10 and MSUB15 are a precision piece of equipment and requires regular attention to maintenance in order to give long and
reliable service. NEXO recommends regular testing of loudspeaker rigging components, preferably using a suitable test rig
coupled with a visual inspection.
These fasteners should be regularly checked and tightened as necessary.
Routine inspection is required for all entertainment rigging systems in order to properly maintain the systems and provide a safe
working environment.
Inspect components for damage or loose hardware visible, if defects are found, the component must be discarded.
All technical operations such as heat or surface treatment, grinding, welding are prohibited on Rigging components.
After cleaning, the rigging system must be treated with a suitable lubricant to prevent rusting. NEXO recommends the use of
ScottoilRFS365 which is a water-based lubricant with a mixture of machine oil, surfactant and anti-rust treatment.
The metal components of the GEO M10 and MSUB15 should not show any signs of deformation, indentation, or rust. They must
be securely fixed to the cabinet.
Any cabinet incorporating a part showing signs of nonconformity must be put aside and inspected by qualified service personnel.
Check the security features of the parts.
Once a year, it’s mandatory to check all the rigging parts

GENERAL INSTRUCTIONS Page 7/29
2.4 Recone procedure: LF driver HPB10N R2
Tools and materials required.
. Cutter (Stanley knife or similar)
. Chisel 15mm or 18mm
. Araldite 2014 (www.araldite.com)
. Masking tape & Double face adhesive tape
. Soldering iron & solder
. Testing facilities - Multimeter, signal generator, Amplifier
The repair procedure for bass drivers is almost the same one for other Nexo chassis loudspeakers.
1. Once the reason for failure has been established and a recone is necessary, strip the chassis in the normal way using
the cutter and chisel, ensuring that the coil gap is covered with tape. It is good practice to Vacuum or blow the dirt away
from the chassis before removing the tape.
2. Use double adhesive tape to further clean the gap. Repeat this process until tape comes out clean, it should be nothing
remain in the gap.
3. Apply the contact type adhesive without excesses, on the frame around the spider mounting surface in first and the
cone surround surface after.
4. Place the new cone assembly in the chassis, making sure the lead wires are aligned with the terminals.
5. Insert all the centring gauges (plastic shims) vertically and evenly spaced through the air gap, between voice coil and
pole center. Don’t let the glue go off. Immediately after, push down on the cone lightly to make sure the glue impregnates
both the spider and the surround.
6. Glue the gaskets in place with the same glue and making sure that there is into correct alignment with the mounting
holes in the chassis. Place a wooden board or another loudspeaker upside down on top of the repaired unit to keep
pressure on the glued gasket.! Let the glue cure for 24 hours!
7. Solder the braid wires to the terminals. Making sure solder does not run up the braid towards the cone. Remove the
centring gauges (shims) slowly.
8. Test the loudspeaker starting at a frequency of 40Hz and a low power level. Increase the level to around 13v and listen
for any rubbing noises and distortion.
9. If all is OK the dust cap can be fixed in place. Use a piece of sticky tape folded over to form a ‘T’ shape and attach
inside the dust cap. Apply a bead of glue around the lip of the cap. Place a small weight on top of it to ensure it meets
the cone all around.
10. Once the glue is dry, using a brush to apply the waterproof treatment (the small bottle) on the cone and the dust cap
(only on the front face).
