Beneath each of the time display windows are the
numbered Timer Operate buttons (1-4). Press the
appropriate Timer Operate button to start the product
timing cycle for a cook sequence.

The next operational procedure to be performed at the
end of the current cycle appears in the text display
window and the remaining time of the current cycle in
the time window.

When the current cycle is complete (Time = 00), an
audible signal sounds and the time display flashes.

The displayed procedure must be performed at this
time.

During this alarm period, the next cycle has
started and the time display shows the remaining
time of this next cycle of the product sequence
when the alarm is cancelled.

The next operational cooking procedure to be performed

appears in the display window when the audible signal
is cancelled.

The audible signal can be programmed for manual turn­off or automatic turn-off. (Refer to the Programming
Mode section).

After all the timing cycles of the selected product
sequence are completed and the final alarm cancelled,
the timer returns to an idle state with the text display
showing the menu item just prepared and the time
display showing four dashes.

procedure for another channel, press and hold the button
of the desired timer channel.

Release the button to return the displays to the channel
closest to completing a cook cycle.

Two cook sequences of the same product can be
performed simultaneously. Each numbered Timer
Operate button initiates an independent cook sequence.

When both Timer Operate buttons are used, an arrow
and an asterisk is shown in the text display window, in
addition to the upcoming operational procedure to be
performed.

The arrow points either left or right, indicating which
channel is closest to completing the current cook cycle
(Time = 00). This is also the channel that must perform
the displayed operational procedure. The time display
window shows the countdown time for the channel to
which the arrow points.

The asterisk means that another product sequence is
also being timed.
