Multi-Display 16-Channel Timer
Operation
1
Press a channel button to activate a timing cycle. The LED
indicator turns green and a short beep sounds. As the time
counts down, the display alternates between the product name,
current duty function (i.e. BAKE), and the remaining time. (All
channels can be activated and running at the same time.)
NOTE: If the time is programmed in hours and minutes (H:M),
the color in the middle of the 4 digits will flash. If the time is
programmed in minutes and seconds (M:S), the color in the
middle of the 4 digits will be on continuously.
Each product has the option of dividing its cooking cycle into 1 to
4 sections called "duty cycles." See the default "Product Library
Table" on page 10 for more information.
NOTE: To cancel any timing cycle, press the channel button
three times in quick succession.
Press the button with your finger only. NEVER use any object to
activate the channel buttons. Such misuse may damage the unit,
voiding the warranty.
CAUTION
3
Press the channel button once to cancel the alarm and to start
timing the next duty cycle.
If this was the last duty cycle of the complete cooking cycle, the
channel returns to an idle state or automatically begin another
cooking cycle (see "Auto Re-Start").
NOTE: Each channel has a multi-colored LED located just
above the channel number. This LED shows the status of the
timing cycle. The LED remains off until a channel has been
activated. Once a channel is activated, the LED turns green until
the timing cycle is complete. After the cycle is complete, the LED
flashes red.
Multi-colored LED
2
The time value counts down from the programmed value to 0:00.
When this duty cycle is finished, the display flashes the end of
duty cycle action that is to be performed (i.e. TURN), and the
alarm sounds.
Auto Re-Start
Any product set up for Auto Re-Start has a small red LED in the lower
right corner of the display. See the default "Product Library Table" on
page 10 for the complete list of products with the Auto Re-Start feature.
When the channel button is pressed to cancel the end-of-cycle alarm
for the last duty cycle, the channel will not return to an idle state.
Instead, it automatically re-starts the entire cooking cycle.

Cleaning
Using ONLY a clean damp cloth, wipe the face and other surfaces of the
755-HM16WA timer unit, as necessary. If desired, a mild soap may also
be used.
NEVER use chemicals and/or degreasers of any kind! Long-term use of
certain chemicals has a negative effect on the surface of the timer, making
it brittle and easily damaged.
