• 1, 2, 4, 8 min : When the receiver cannot receive any signal from a satel-
lite for 5 minutes, the GPS receiver power is turned OFF
for the selected periods (1, 2, 4 or 8 minutes). After this
period, the receiver resumes receiving.

lite for 5 minutes, the GPS receiver power is turned OFF
for 1 minute. After this period, the receiver resumes re-
ceiving.
