Setting the Controls
The model 247 & 248 Toaster Grills provide two modes of
operation: DEDICATED MODE and PRODUCT MODE.
•DEDICATED MODE is a simple mode of operation for toasting
buns that is similar to the 213, 411 & 416 Series Toaster Grills,
with a set toast time and temperature for one product “BUN1”.
•PRODUCT MODE allows you to set both the toasting time and
temperature individually for four additional products. Note that
it may take several minutes for the platen to heat up or cool
down to a new temperature setting. You can also change the
display to any four character name of your choice for each of
the products to indicate which product is being toasted.
• Furthermore, 247 and 248 Toaster Grills allow you to manually
initiate the power-saving mode. (See Figure 1.) Figure 1
