OVEN MODES
Updating the Firmware
From the oven off screen,
1. Insert the gray smart card (see Figure 13, page
13) with the gold chip facing the front of the
oven. If multiple smart cards are required, they
will be labeled in sequence - ensure the correct
sequence is followed.
2. From the COOLING DOWN or OVEN OFF MODE ,
press and hold the idle key until the oven resets
(approximately 5 seconds). The display will go
blank until the upload is complete.
3. When the oven beeps one long high tone, the
load was successful. If a second card was
provided, insert it.
4. When the oven restarts and the display turns
on, the update is complete. Remove the smart
card from the oven.
NOTE: If the update is unsuccessful, the display
will remain off and the oven will beep one long,
low tone. If this occurs, repeat the above
procedure. If the update fails multiple times, a
smart card may be damaged.
Please note that the
oven will be inoperable until a successful update is
performed.
As such, TurboChef reinforces proper
handling of smart cards to help prevent static
damage, and recommends that each service
technician keep a backup copy.
