There are 3 event messages which automatically disappear after 5 minutes or simply by
pressing a key:
Err Bat Displayed each time a power drop near the 9V threshold is detected (safety
threshold). Returns to normal if the battery exceeds this security level after a few seconds.
Err MEM Displayed on powering on if a memory malfunction occurs.
Err Bus Displayed at the first detection, after powering on, if a bus wire is pinched (incorrect
wiring).
