* All 8500 series models, with the exception of models 8524 and 8526, can be configured for 110 V or 220 V operation via the AC line switch in the rear
panel. Base models 8524 and 8526 operate with 110 V only. For 220 V operation, order model 8524-220V or 8526-220V respectively. “-220V” denotes
220 V operation only and these models cannot be reconfigured for 110 V operation.
