Scroll with the ▲/▼ keys until RTC Test is highlighted. Then press
OK to accept.
You will notice the Date (YYY-MM-DD) and Time (HH-MM)
appear on the top of the screen.
Beneath the date/time line you will see:
00(s) : 08(ms).
The line above represents seconds(s) and milliseconds (ms).
Press OK once and the seconds and milliseconds advance in
real-time, as does a stop watch.
Each time you press OK, the “stop watch” will reset to zero and
then start again.
If the clock is operating correctly, press ESC at any time to return
to the Auto Test Menu.
