Vertical toasters can accommodate up to five or six slices with a reduced slice selection switch for economy in quieter periods. They both utilise an automatic element timer for consistent results. Once cooked, the toast can remain warm in the machine before being manually ejected. Note that the units are designed for continuous use. A change in selection to the number of slices toasted will require a period for element temperatures to equalise. Uneven toasting may result during these transitional periods.
