report. When the GPS receiver cannot acquire a fix, HACC gradually increases and, at some
point, stops at a value of 4294967.500. It is an indication that the surrounding obstructions
prevent the GPS receiver from obtaining a fix and you should move on to a different
location.

RIDIUM
The Check Iridium [
Chk Iridium
] option forces the SHOUT ts to turn on its Iridium
transceiver and continuously update and display signal strength in real-time. The
Iridium transceiver remains on until you leave this screen by pressing the back button. Be
careful not to deplete the battery power by staying on this option for too long.

When the Test Report [
Test Rpt
] option is selected, the SHOUT ts immediately turns
the GPS receiver on to update its location data. The location information is
continuously updated and displayed in real-time whether there is a valid fix or not. Similar
to the Chk GPS option, you can monitor HACC to determine if a valid fix is possible. Once a
valid fix is obtained, the GPS receiver is turned off and the most recent 3D fix information is
displayed on the screen. This information (called test report) can be forced to send to a NOC
server by pressing
Send
. A test report has the same format as a regular position report and
is treated as such by a NOC. Sending a test report does not disrupt or change the tracking
reporting rate.
The
Test Rpt
option is a good diagnostic tool used to ensure proper operation of the GPS
receiver and the Iridium transceiver. It can also be used to manage battery life by turning
off tracking mode and strategically sending on-demand location reports. It can be
considered as “manual tracking mode.”

Use the Check-In [
Chk-In
] to send a quick message with a single, easily accessed
button. When you press the Chk-In button, a second screen appears requesting
confirmation. Once confirmed, the SHOUT ts sends out a reserved canned message code
representing a Chk-In message. If the Texting/Inc GPS option is enabled, GPS location is
attached to the Chk-In message. Chk-In messages with GPS location take longer to
complete because the SHOUT ts has to acquire a GPS fix first.
