TROUBLESHOOTING
Info Screen
The info screen (Figure 24, page 16) is used to
display the following information in an easy to
access place:
- Serial number
- Electrical compartment temperature
- Voltage
- Total time the oven has been on
- Total time the oven has been idle
- Firmware version
To access the info screen, press R3 within the setup
mode (Figure 21).
Updating the Firmware
From the oven off screen,
1. Insert the gray smart card (see Figure 25) 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 and repeat steps 1-3.
4. Remove the smart card from the oven. The
oven will restart.
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.
