SAFETY WARNING!
Mains electricity is dangerous and can kill. Mains voltage is
present within the console power supply unit.
The internal power supply unit contains no serviceable
components and must be replaced as a complete unit if a failure
occurs.
Do not remove the power supply cover with mains electricity
connected. To ensure your safety, mains earth is connected to
the chassis through the power lead. Do not remove this mains
earth connection.
To avoid the risk of fire, replace the mains fuse only with the
correct value and type as indicated on the power supply unit.
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.
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.
WARNING: There is danger of explosion if the battery is incorrectly replaced.
