LED
The SHOUT nano has a single status LED
at the top-left corner to alert you whether the
device is in tracking mode or emergency mode. The LED flashes once every five seconds when
Tracking On/Off
is enabled and the device sleeps (in between tracking reports). The LED turns
solid green when emergency mode is enabled regardless of whether the device is on or off. The
LED can be turned off for either of these two cases to save battery power using the LED option.
The SHOUT nano consumes approximately 3 mA less with the LED disabled during emergency
and 125 μA less with LED disabled during tracking mode.

NCLUDE
GPS
The
Include GPS
option forces the SHOUT nano to attach GPS location to Check-In,
canned, and free-text messages. Under the default setting, these messages do not have
GPS information included. Messages with GPS location included can take longer to complete
because the SHOUT nano has to acquire a GPS fix first. Depending on the validity of the stored
ephemeris data or the Accuracy setting, it could take an additional 29 seconds.
8.6
GPS
The
GPS
option gives access to the
Position Format
and
Position Model
settings.
Use the Position Format option to select one of three different GPS position formats to be
displayed on the LCD screen. Do not confuse this option with the Format option under Tracking,
which defines the format of a position report to be transmitted to a NOC.
The Position Model option allows the GPS receiver to be more accurate by telling the unit what
its environment is like. For applications operating below 12 km, the Portable setting is
sufficient. If operation above 12 km is required, refer to the “AT Commands for SHOUT nano”
[1] document for details.

option to select UTC time and date formats to be displayed on the
LCD screen for all menus. The local time zone can also be set.
