Service and maintenance
Warning! Read “Safety Information” on page 4 before carrying out service on the VC-Grid.
Warning! Isolate the installation from AC mains power before servicing.
Warning! Refer any service operation not described in this manual to a qualified service
technician.
Important! Read ”Electrostatic discharge precautions” on page 6 before carrying out
service on the VC-Grid.
Important! Excessive dust buildup causes overheating and a risk of short-circuits and will
damage the product. Damage caused by inadequate cleaning is not covered by the product
warranty.
The user will need to clean the VC-Grid periodically. All other service operations on the VC-Grid must be
carried out by Martin Professional™ or its approved service agents.
Installation, on-site service and maintenance can be provided worldwide by the Martin Professional Global
Service organization and its approved agents, giving owners access to Martin’s expertise and product
knowledge in a partnership that will ensure the highest level of performance throughout the product’s
lifetime. Please contact your Martin supplier for details.
Cleaning
Cleaning schedules vary greatly depending on the operating environment. It is therefore impossible to
specify precise cleaning intervals for the VC-Grid. In extreme cases, the product may require cleaning after
surprisingly few hours of operation. Environmental factors that may result in a need for frequent cleaning
include:
• Use of smoke or fog machines.
• High airflow rates (near air conditioning vents, for example).
• Presence of cigarette smoke.
• Airborne dust (from stage effects, building structures and fittings or the natural environment in outdoor
locations, for example).
If one or more of these factors is present, inspect products soon after installing them to see whether
cleaning is necessary. Check again at frequent intervals. This procedure will allow you to assess cleaning
requirements in your particular situation. If in doubt, consult your Martin™ dealer about a suitable
maintenance schedule.
Important!
Electrostatic discharges may cause damage. Do not touch the VC-Grid with fingers or a compressed
air nozzle.
To clean the product, use low-pressure compressed air to gently remove dust and loose particles from the
front and back of the product. Avoid touching the product’s conductive surfaces and electronic components.
Installing new software
It may be necessary to upload new software (i.e. device firmware) to the VC-Grid if it appears to have a
software-related fault or if you want to update to a newer software version.
Software for Martin™ products is available from the Martin website. The VC-Grid software can be installed
from the P3 System Controller over the P3 data link. See the P3 System Controller user manual for software
installation instructions.
