Note: When you suspend the Allegro 2, the receiver is in a
low power mode to retain its almanac. When you resume, it
takes a few seconds to get a fix.
GPS/GNSS Accuracy
The GPS/GNSS antenna is in the top of the Allegro 2. Do not
put your hand or another object over the top bumper or
display. This reduces accuracy. The more items between you
and the satellites, the lower the accuracy.

To view or make changes to the GPS/GNSS settings or set up
an external GPS/GNSS receiver, press and hold the GPS/GNSS
status gadget on the Home screen to open the GNSS control
panel.
Scroll through the menu and set up the desired parameters.
Select from pull-down lists and enable or disable
checkboxes and circles by selecting or deselecting them.
