Clearing the LRC code
LRC on the display is due to the EEPROM memory corruption. This is typically caused by a large power
disturbance. Normally all that is necessary is the unit will have to be reset, and the values in the variables
re-entered. This can be done by holding the “diAG” key while the power to the unit is off, and continue
holding the “diAg’ key while the power to the unit is restored. The unit will say “RESE”. When the
“RESE” is displayed the “diAg” key should be released. It should now no longer display the LRC and
you should be free to reprogram at this time.
