duration can take up to two minutes depending on the Iridium satellite visibility and the validity
of the GPS ephemeris data. Ephemeris data saved on the GPS receiver is valid for approximately
two hours, allowing the receiver to obtain a hot-start fix. Report rate (time between reports)
set to more than two hours forces the GPS receiver into either a warm-start or cold-start fix
(approximately 29 seconds). As a result, the SHOUT nano will consume more battery power and
the total number of reports is significantly reduced. Read
more information.

Note
: When the SHOUT nano is in the middle of sending a report and a user forces it to power
off by holding down the power
button, the SHOUT nano attempts to complete sending the
report before shutting down. A warning message appears on the LCD screen and remains until
either a position report is sent or fails to send. Go back to the home screen by pressing the
BACK button.
The SHOUT nano logs and saves all position reports in its circular memory. When its memory is
full, the oldest reports are overwritten. SatTerm can be used to retrieve all position reports
saved on the SHOUT nano.
