IMPORTANT
McLane recommends setting the RTC during the power-up sequence. When the MMP is
powered on, the clock defaults to January 1,1970, 00:00:00. Set the clock to any date and time
in the allowed range and the count will continue from the new value.

NOTE
The electronics board contains a temperature-compensated crystal oscillator (TCXO) for time-
keeping as reliable as -0.5 min/year to +1.5 min/year (in a temperature range from 0°C to
+40°C).
<2> Diagnostics
Diagnostics is a scrolling display of status information including the RTC, WDC, battery
voltage and motor current (mA). The nominal voltage of the lithium battery pack is 10.8 V. A
new battery generates approximately 11.6 V but drops to the nominal value after some use and
stabilizes for most of the usable battery life.
A sample Diagnostics display is shown in Figure 7-6. Typing ‘X’, ‘x’, or [CTRL]-[C]
exits from Diagnostics and returns to the Main Menu. The display can be toggled on and off
without leaving Diagnostics by pressing any other key.
