Troubleshooting
Electronic maintenance on the CFG253 Function Generator must be
performed by a trained technician. However, an operator can perform
some basic and routine maintenance. The CFG253 Function
Generator will give some indications of problems to aid the operator.

disconnect the signal input cable from any signal source before
checking or replacing the fuse.
If the power on indicator does not light when the POWER switch is
in the on position, check the power line fuse.
