7. Service and Maintenance
If for any reason your Ohm product fails, contact the Ohm Technical Support (support@
ohm.co.uk) or your local dealer (check the Ohm website), this applies to both warranty and
non-warranty faults.
Faulty rigging parts can potentially cause serious consequences and liabilities, so for any rigging
hardware problems contact Ohm to determine the appropriate service solutions.
The metal components of the cradles and stacking systems are covered by a textured powder
coating which will protect them against short term moisture. All the cabinets and rigging parts
should always be stored, transported and used under dry conditions. CT-10, CT-12 and CT-15 are
not designed for long-term outdoor use.
7.1 Performance Testing and Periodic Inspection
Complete inspection of the enclosure and a listening test and formal measurements should be
done periodically. The interval between such tests will depend on system usage and the conditions
of use, but make sure these inspections are made at least yearly. All the transducers should be
tested regularly to make sure they work as intended. A sine wave sweep at approximately 10% of
rated power will usually reveal possible transducers and enclosure problems, faults usually cause
some distortion, buzzes or rattles.
Faults in internal components and wiring usually cause transducers to stop working or to be
intermittent. Only trained technicians may inspect and fix the connection problems.
Take extra care when inspecting all the rigging hardware. Visually inspect all rigging parts each
time they are used to detect all possible conditions that may affect load handling capability (i.e.
wear, deformation, cracks, corrosion).
7.2 Cleaning and Cosmetic Repairs
If the exterior surface requires cleaning, use a damp cloth to remove any dust and dirt and use a
dry cloth to finish the cleaning. Do not use any cleaning solvents or abrasives.
All the CT range cabinets are painted with a high quality paint. Enclosures that are designed
for road-use, may over time show signs of wear and tear during normal use, for paint touch up,
contact Ohm or your dealer for re-painting or to purchase the touch up paint and instructions for
its application. Before paint touch up, fix any cosmetically damaged wood parts using common
woodwork methods and materials.
