 the log.) 
The error popup indicates only the top priority error. If there are a plurality of errors, fix them one by one and restart until all the errors are fixed.MacAddress NG > MemoryError flag > LowBattery flag
The following error popups are shown according to the contents of error:\
Mac Address NG:  “Illegal MAC Address! Cannot Use Ethernet.” Memory Error:  “Memory Error! All Memories Initialized.” Low Battery: “Low Battery!” 
W h e n t h e i n d i c a t i o n i s c h a n g e d t o t h e i n i t i a l i z a t i o n m e n u s c r e e n , t h e i t e m “ I n i t i a l i z e A l l Memories” is usually selected. However, the item “Fader Calibration” will be automatically selected when the indication is changed to the initialization menu scree\
n in case of “Fader NG”. 
*2The following is the battery condition indication in the Setup screen ju\
st after the start-up. The indication depends on the detected voltage. The voltage is measured every 10 minutes.
*3The error popup “Low Battery!” will appear if the battery should be replaced after the normal start-up as well. However, no popup will appear if the error popup “Low Battery!” is already shown at the initialization menu screen to avoid overlap.
Notes:1.The GUI does not show all the errors if there are a plurality of simultaneous errors, therefore, they can be fixed only by repeating fixing procedures. 
2.Under a situatoin where “Low Battery!” Popup is displayed, the battery voltage is 2.2 V or less but the memory is not still damaged, if an error of power fan, internal or external power supply is detected, the power supply related Error Popup may be given priority depending on timing.
∗ The same indication will appear in both cases. The only difference is the presence or absence of popup at the start-up.
