When using the SLM Utility-G3 software to control the
Model 831, there are two operational modes for the GPS:
GPS On
In this mode, the GPS is always on and consuming power,
but the
GPS tab is also always being updated. This can be
useful for real-time tracking of location or time.
GPS Auto
In this mode, the GPS will turn on at two different time:
• At the beginning of an interval, the GPS will turn on to
record the location
• During a daily autostore, the GPS will turn on to check
the time and update the internal clock if needed
Time Zone
Setting the GPS to On will open the menus to select the time
zone in which the GPS is located, as shown in FIGURE 18-
27
