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.

Removing the Power Supply PCB (DL1000)

Before beginning any service work, remove all power to the unit and disconnect any signal cables where necessary. Adopt static electricity working procedures when carrying out service work. Ensure adequate lighting and use the correct tools. Access to the Power Supply circuit board can only be achieved once the console has been opened (see ‘Opening up the DL1000 console’).

1) Turn the console base over to reveal underside. Referring to fig.4 remove the 3 heat-sink screws.

3 heat-sink screws

fig.4

2) Remove the 2 XLR screws from the rear of the base and drill out the 2 Mains Inlet IEC pop rivets (see fig.5)

3) The Power Supply circuit board assembly can now be removed from the console.

When all service work is complete, remove all debris such as solder, component legs and wire clippings from inside the unit and check your work carefully before re-assembly. To refit the Power Supply circuit board assembly, follow the above procedure in reverse order. Make sure all Earth wires are aligned and plugged on. Test for correct operation.
