F11 - Set time and Date
A RTC fault occurs when the system detects an incorrect date setting. This could indicate that the time and
date has not been set correctly or that the RTC battery (small battery on the VS-MKII control module PCB) is
faulty.
Figure 76 - RTC battery
To diagnose the cause of the RTC fault follow the instructions below:
1. Use the ‘F5’ command to check the current time and date.
2. If the time and date is incorrect, use the ‘F11’ command to set the current time and date. Check first
that the PC you are using has the current time and date set correctly.
3. Verify that the time and date are now correct by again using the ‘F5’ command.
4. Perform a system restart (refer Page 16, Step 6)
NOTE: The RTC battery has an expected life of 10years but if the Real Time Clock has defaulted to the date
of “01/01/00” it is necessary to replace the RTC battery and then follow the steps detailed above.
F12 - Capture log file
The F12 key will capture all of the relevant system data and event log for troubleshooting purposes and will
also automatically save a text file for later analysis.
