These controls are factory set; under normal circumstances, no further adjustment is required. If adjust- ment is needed, unplug the MCP35A and remove it from the enclosure. Remove the top cover and make an approximate adjustment. Replace the top cover and plug the unit back in. Test if the new set volume is accept- able. Repeat procedure if necessary.
