1. IMPORTANT SAFETY INFORMATION

WARNING.

Any person performing the procedures described in this manual will be exposed to hazardous voltages and the risk of
electric shock. 4

Carver Corporation assumes that any person who removes the cover from the unit has been properly trained in protecting
against avoidable injury and shock.

Therefore, the procedures described here are to be performed by qualified electronics service personnel only.

We recommend that the unit be tested only when line isolation is provided by an isolation transformer. The line cord of
the unit must be disconnected and the power supply capacitors fully discharged before any components are replaced.
Failure to do so may result in severe damage to the unit and the risk of electric shock.
