Equipment Handling

All Digital Audio Communication System Circuit Boards and Modules are sensitive to electro-

static discharge (ESD). To avoid damage to DACS equipment, proper ESD procedures should be

followed when handling all Digital Audio Communication System equipment. If it is necessary to

remove and/or replace a circuit board or module, follow the procedures listed in Chapter 5, Test

and Maintenance.

Ensure that all work is performed at a properly grounded ESD work station. In addition, all per-

sonnel handling DACS equipment should be properly grounded.

When transporting or shipping individual modules, equipment should be fully enclosed in an anti-

static bag.
