MAINTENANCE
Cleaning:
When wiping out the SDC25/26, use the soft and dried
cloth. Do not use a detergent or an organic solvent like
thinner or benzene.
Parts replacement: Do not replace the parts.
Fuse replacement: On AC models, when replacing the fuse for the power,
make sure that the replacement fuse complies with
applicable standards. Use a time lag fuse (T) compliant
with IEC127 and rated at 250V, 0.5A.
