1. You need to copy and paste the firmware ( a .bin file) into root directory of an U-disk.

2. Change the firmware name of this bin file to “image.bin”.(The names of the firmwares of ER220G,ER520G,MCR30 or ECR100F don’t need to be changed)

3. Turn down ECR and plug the U-disk into USB port of ECR.

4. Press and hold the upper right and lower left keys simultaneously. You can’t release these 2 keys until the display shows some words such as “PASSWORD” after turning on ECR.

5. Enter the password “246810”.If the password is correct, the firmware will be updated automatically, or you will be requested to enter password again.

6. After the update is completed, the machine will automatically restart.
