7. Service

The included attenuator security covers (Figure 4.2) can replace the existing level-control knobs so that the ampli fi er output level cannot be changed. The knobs snap into

the front panel.Crown products are quality units that rarely

require servicing­. Before returning your unit for service, please contact­ Crown Technical Support to verify the need for servicing.

This unit has very sophisticated circuitry which should only be serviced by a fully trained technician. This is one reason why each unit bears the following label:

CAUTION: To prevent electric shock, do not remove covers. No user serviceable parts inside. Refer servicing to a qualified technician.
