3E. Firmware updates
There are three firmwares required for the e1s: QTS, SRB and Icon. All firmwares are pre-installed but may require updating
as per instruction from the manufacturer or as part of hardware replacement. Firmwares are updated by loading the
required files to a USB memory stick and then downloading this information to the appliance using the USB memory stick
slot on the oven.
Procedures to load USB sticks and download to appliance
Important notes:
Downloading from a USB memory stick will clear all existing programs.
Only use an empty USB memory stick (up to 128GB) formatted as FAT32.
Copy the following firmware files to the ROOT directory of the USB memory stick:
o QTS-eX-XXX-VX.X.XX.BIN
o SRB-eX_X_X_XXX.BIN
o VX-APP-eX.CBR (icon file)
o Autoupd.ATE (for auto update only)
The USB memory stick should be formatted to FAT32 with firmware loaded.
Do not remove the USB memory stick during the download sequence as this could corrupt the data transferred
from the USB stick.
Save the menu files before uploading files.
If you have a menu file on your USB memory stick then the menu of the appliance will be overwritten.
If you do not have file on your USB memory stick the menu of the appliance stays as it is.
There are two methods for installing firmwares: manual or automatic. Automatic is the simplest method as it ensures that all
three firmwares have been updated at the same time. Manual update is used when one or other of the circuit boards has
been replaced.
For manual update follow all instructions in the Manual updates section given below.
For automatic update ensure the Autoupd.ATE is on the USB memory stick then follow the instructions in the Automatic
updates using Autoupd.ATE files section.
Manual updates
1.
With the oven switched off, open the cover of the USB port and insert the
USB memory stick into the slot.
The USB memory stick should be formatted to FAT32 with firmware loaded.
2.
Switch on the oven and tap the top-right hand corner.
