For continued protection against risk of fire, replace only
with same type and rating fuse(s). To reduce the risk of
electric shock, leakage-current or resistance measurements
shall be carried out (exposed parts are acceptably insulated
from the supply circuit) before the appliance is returned to
the customer.
