Updating the Firmware
M160/M161 5-10 SM
Firmware Update Error
If firmware update fails, an error code appears.
An error message shows in the first line if an error occurs during the download.
The error code consists of the letter "E" and a number (for example, "E36"). For details, refer to
the Error Message Table. (Handling Firmware Update Errors in this section)
Recovery after Power Loss
If the ROM update is interrupted as a result of accidental loss of power while the firmware is
updating, then the correct operation of the machine cannot be guaranteed after the machine is
switched on again. If the ROM update does not complete successfully for any reason, then in
order to ensure the correct operation of the machine, the ROM update error will continue to show
until the ROM is updated successfully.
In this case, insert the card again and switch on the machine to continue the firmware download
automatically from the card without the menu display.
