Federal Communication Commission Statement (FCC, U.S.)
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in an installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one of the following
measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.

This device complies with RF radiation exposure limits set forth for an
uncontrolled environment. This transmitter must not be co-located or operating
in conjunction with any other antenna or transmitter.
This device must operate with a minimum distance of 20 cm between the radiator
and the user body.
FCC Caution:
Any changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate this equipment

Chapter 1 – Introduction
Purpose
The multi-purpose Industrial Tracker GTG21 is designed for outdoor asset
tracking and industrial purposes. Batteries are replaceable and the device is
designed to operate for many years. The sensor includes a three-axis
accelerometer which is used to optimize different asset-tracking applications
for response time and battery lifetime. The sensor also includes many unique
GPS acquisitions and geo-fencing features for optimal battery lifetime and
response time. A new Bluetooth feature is added to aid GPS acquisition and a
buzzer to alert users.

Note
Chapter 3 – Operation
Flight Mode
When industrial trackers leave the factory, they are put into flight mode,
where the sensor is hibernating without functionality to prevent radioactivity
and minimize battery usage. Devices are delivered in this mode. G-sensor will
not be ready to receive commands though it has not been disabled.
When the device is commanded by a network, the device shall exit shipping mode
and enter default mode. If the device fails to join the network after trying
32 times, the device will revert to flight mode. Another way to enter flight
mode from normal mode is when the device has not received ADR ACK for at least
56 hours.
Normal Mode
This mode is active when the device is in normal operating mode. When the
device detects a magnetic tap, the green LED shall flash according to the
remaining battery voltage. For example, 4 times within 800ms for full battery,
or once if a low battery condition is detected. After the motion, the device
will turn on GPS acquisition once it remains at rest for 45 seconds. 3
Position updates then will be sent to the network.
Chapter 4 – Installation
Usage
Sturdy design to endure the weather with an enclosure of IP67 rating and
plastic withstanding temperatures ranging from -20°C ~ +70°C ambient.
Two tabs on the side for numerous ways to secure, such as ties to the rear
mirror and the steering wheel.
Battery Replacement
Remove the bottom cover of the tracker.
Replace both batteries and use only ER14505
Do not mix used and fresh batteries.
