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.
