A.2 Critical Issues of Upgrading
1.You can abort the upgrading process by pressing the “Esc” key on the host PC during the upgrading process. The LES301A will restart automatically, and the system remains intact.
2.If the LES301A does not receive any upgrading data within 30 seconds, it will restart automatically and the system will remain intact.
3.After the upgrading process finishes, the LES301A will program the flash memory, and the buzzer will beep 6 times, then restart. Normally, it takes about 10 seconds to complete the programming process. If an error occurs during the programming process, the LES301A will clear the corresponding memory, and the system remains intact.
