WARNING: There is danger of explosion if the battery is incorrectly replaced.
The information presented in this section of the manual is intended for competent technical personnel to
carry out service and product support for the icon series. We assume that the reader is familiar with
the related electronic theory and audio terminology, and is able to carry out basic servicing, fault-finding
and repair of digital audio equipment of this type. Service personnel should also be familiar with audio
systems, mains earthing and power requirements, as well as handling precautions.
For information on the installation, operation and application of the icon series please refer to
the User Guide.
Whilst we believe the information in this manual to be reliable we do not assume responsibility for
inaccuracies. We also reserve the right to make changes in the interest of further product development.
Service and Technical Support
Under normal operating conditions the icon does not require user maintenance or internal calibration.
Any service work required should be carried out by qualified technical personnel only.
We are able to offer further product support through our world-wide distribution network. To help us
provide an efficient service please quote the unit serial number, the date and place of purchase in any
communication regarding this product.

correct value and type as indicated on the power supply unit.
Replace the battery with an Allen & Heath recommended part. Using a different battery, recharging or
disassembling the battery may present a danger due to fire or explosion.
Dispose of used batteries promptly according to the manufacturer’s instructions. Keep all batteries
away from children.
IMPORTANT STATIC ELECTRICITY PRECAUTIONS
Many of the components in the icon are extremely sensitive to static electricity. The following
procedures reduce the possibility of damaging components:
1) Before handling any components or touching anything inside the unit, discharge your
body’s static electric charge by touching a grounded (earthed) surface. Wear a grounding
wrist strap if one is available.
2) Do not remove parts from their antistatic containers or bags until you are ready to install
them. When removing circuit boards (PCBs) or ICs from a unit, immediately place them in
an antistatic bag.
3) When handling PCBs, hold them by their edges and avoid touching the circuitry.
4) Do not slide PCBs or ICs over any surface.
5) Avoid having plastic, vinyl and foam in your work area.
6) Limiting your movements during service work reduces static electricity.

Flightcasing the console
If the console is to be regularly moved we recommend that it is installed in a foam-lined flightcase. At all
times avoid applying excessive force to any knobs or connectors. Do not obstruct the ventilation slots or
position the icon where the air-flow required for ventilation is impeded.
