LX-300 to erase flash memory areas in the DSP,EXP, and ELC modules. You may need to do this if flash memory has become corrupted, or if there is a problemafter uploading system flash. Both situations are rare, and erasing flash memory is not required in normal operation.Try the Erase Flash commands first as they will allow you to erase and then replace flash files without requiring aserial connection to re-load system and ELC flash files.It is important to know that the operating system for the DSP, EXP, and ELC modules is loaded into RAM duringstartup. You can erase the flash memory and the LX-300 will continue to run until power is switched off. If the firmwarefiles are not in flash, the next time the LX-300 is powered up, there will be no operating system to load and thesystem status display will show “/EP\” to indicate that the LX-300 is operating from diagnostic code in the EPROM.Normal operation will not be possible until the operating system has been re-loaded into flash memory and the LX-300 power cycled.There is also a diagnostic setting of the ID to force the LX-300 to run from EPROM. If you set the Frame ID switchto 00, flash memory will be bypassed during the startup procedure and you will be running in EPROM mode. Torestore normal operation, return the switch to the proper ID and power cycle the LX-300.
