Tracking mode will also load a different tracking profile if Geofences are enabled and the

SHOUT ns enters or exits a geofence. Priorities are assigned to the different stimuli and the

SHOUT ns will only switch to the associated tracking profile if it has a higher priority.

Emergency tracking has the highest priority, Geofence is the second highest, and Normal

tracking is the default.

5.3 Call-Outs and Power-Up Delay

Using an onboard real-time clock, the SHOUT ns can be configured to send daily call-out

reports at specified UTC times. These call-out reports are in addition to tracking reports sent

at a pre-defined tracking interval and they are indistinguishable from each other. Call-outs

can be used as a heartbeat to determine if the device is still operational (see Section 6.2.4

Call Out).

In addition, using the onboard real-time clock, the SHOUT ns can be configured for a

power-up delay. A power-up delay is set for a specific UTC time and date up to 45 days in the

future. When a delay is set and tracking is started, the device will remain in its low-power

sleep mode until the configured date and time upon which the device will power on

automatically and enter the start-up mode. This is useful for conserving battery power while

the tracker is in transit to a destination (see Section 6.2.2.3 Additional Setup Parameters).

The SHOUT ns can utilize location information from its GPS receiver to determine whether

it has entered or exited the bounds of preconfigured geofences. A geofence is a set of

connected latitude and longitude coordinates that defines a region or zone of interest (see

Section 6.2.3 Geofencing). A geofence is defined by a minimum of 3 coordinates and a

maximum of 50. Multiple geofences can be configured, each with a unique set of tracking

parameters that will cause the SHOUT ns to change its tracking behavior while in a specific

geofence. Each geofence can also be configured to send a report upon entering and exiting

the defined geofence region. In addition, geofences can be configured to turn off the Iridium

modem for regions that require radio silence.

The SHOUT ns has a built-in sensor that can reliably detect motion. It is an omni-

directional movement sensor and will function regardless of how the SHOUT ns is mounted or

aligned. It is sensitive to both tilt (static acceleration) and vibration (dynamic acceleration).

The signal level is fed directly into the SHOUT ns micro-controller to "wake up" the SHOUT ns

out of low-power mode when activity is sensed and to transmit location report. The motion
