In addition, using the onboard real-time clock, the SHOUT nano 100 can be configured for a
turn-on delay. A turn-on delay is set for a specific Coordinated Universal Time (UTC) time and
date up to 45 days in the future. When a delay is set and tracking is started, the device remains in
its low-power sleep mode until the configured date and time upon which the device will turn on
automatically and enter the start-up mode. This is useful for conserving battery power while the
tracker is in transit to a destination.

EOFENCING
The SHOUT nano 100 can utilize location information from its GNSS 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 Refer to
the SatTerm for SHOUT nano 100 Manual [5]. A geofence is defined by a minimum of three (3)
coordinates and a maximum of 50. Multiple geofences can be configured, each with a unique set
of tracking parameters that cause the SHOUT nano 100 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.

ETECTION
The SHOUT nano 100 has a built-in sensor that can reliably detect motion. It is an
omnidirectional movement sensor and functions regardless of how the SHOUT nano 100 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 nano 100 microcontroller to wake
the SHOUT nano 100 out of low-power mode when activity is sensed and to transmit a location
report. The motion sensor has a variety of settings that impact its detection sensitivity. The
motion sensor can be enabled or disabled (refer to the SatTerm for SHOUT nano 100 Manual [5].

NCRYPTION
The SHOUT nano 100 can be configured to encrypt/decrypt all transmitted and received data
using 256-bit Advanced Encryption Standard (AES) encryption. To enable encryption, assign a
cryptographic administrator for the device to be responsible for modifying the encryption and
