The AP50MM will prompt a warning message if it detects an abnormal condition or
operation. On screen prompts direct the user to take appropriate corrective actions in
most cases.
If an unspecific error occurs or the AP50MM cannot be turned on, reboot the instrument
by taking a battery out of the battery holder and re-install the battery.
If the AP50MM has been idle for more than two months and cannot be turned on, replace
all four batteries with four new AA alkaline batteries.
A diagnostics page can be launched by press the SYS icon in the main page. The
software version and its associated hash code can be found in the diagnosis page.
