1Introduction
The 3M™ One-Piece GPS Offender Tracking Unit is a wearable device designed specifically for offender
monitoring applications. With security redundancies and anti-tamper mechanisms built-in across the
platform, the One-Piece unit provides a trustworthy and reliable tracking system.
The system integrates tracking, communication, and mapping technologies that enable operators to
efficiently track offenders at varying levels of intensity.
Each monitored offender is assigned a tracking unit which continuously tracks their location in real-time.
The One-Piece unit stores and processes the tracking data and communicates with the monitoring center
or assigned officers to report the offender’s location or alert in the event of a violation. Alerts are
configured according to the offender’s individual schedule and zone restrictions.
The One-Piece unit operates on the 3M Electronic Monitoring software platform and is a result of over a
decade of field experience.

3Charging the Unit
The One-Piece unit can be charged in two different ways; the Cord Charger attachment and the Cordless
Charger. Both charging options can fully charge a depleted battery in 2.5 to 3 hours.
3.1 Cord Charger Attachment
The first method of charging is via the regular cord charger attachment that is supplied in the product kit.
Figure 3: One-Piece GPS Unit with Wall Mount Power Supply and Cord Charger Attachment
The Cord Charger attachment is connected to a wall mount power supply at one end and to the One-
Piece unit’s charging port at the other.
The Cord Charger is attached to the One-Piece unit using two magnets allowing quick and easy
attachment and removal. This method helps to prevent any damage to the device or the wearer in the
event of unintended pulling.
3.2 Cordless Charger
The Cordless Charger is a dedicated attachment including a rechargeable battery that fits to the bottom
of the One-Piece unit. The Cordless Charger connects to a wall mount power supply that recharges its
battery when not in use.
Figure 4: Cordless Charger with Wall Mount Power Supply

When attached to the One-Piece unit, the cordless charger charges the device while allowing the
offender to go about their daily routine unhindered.

4.1.3 Offender Information in the 3M™ Offender Management Software
Verify the following Offender details in the 3M™ Offender Management Software application:
Offender’s name and address
Offender’s program type –1 Piece
Equipment serial numbers –these must match the serial numbers on the equipment you are
planning to install
SIM card details
For more information about working with the 3M™ Offender Management Software, refer to the One-
Piece GPS Offender Tracking Operational Guide.
4.2 Setting Up the 3M™ Curfew Unit
The Curfew Unit is an RF device that monitors the offender’s presence in a fixed curfew area.
Figure 6: 3M™ Curfew Unit
The ideal location for the Curfew Unit is:
As close as possible to the center of the curfew site
On a flat and secure surface
1m above the ground and at least 30cm away from the wall
Not close to the ceiling
Make sure the Curfew Unit is located far away from:
Television sets or other electrical appliances
Microwave ovens
Personal computers or laptops
Heat sources such as a radiator, air duct, or direct sunlight
Excessive moisture or extremely low temperatures
Mirrors or reflective materials

Figure 7: Positioning the Curfew Unit

If the house has two floors, it is recommended that you install the Curfew Unit on the first floor.
If the house has three floors, it is recommended that you install the Curfew Unit on the middle
floor.
To install the Curfew Unit:
1. Place the Curfew unit in position according to the recommendations above.
2. Connect the Curfew unit to power.

The Curfew Unit includes a rechargeable battery that enables the unit to continue functioning in
the event of a power outage. This battery is recharged automatically and recharging is not
controlled by the user.

4.3 Checking the One-Piece GPS Unit’s Battery Status
To check the One-Piece GPS Unit’s Battery Status:
Press and hold the Activation button on the front of the One-Piece unit for one second.
The PWR LED flashes green once.

If the PWR LED flashes red, or not at all, the One-Piece unit needs to be charged.
4.4 Attaching the Tamper Plugs
On the rear of the brackets on the One-Piece unit, attach tamper plugs.
To attach the tamper plugs
1. Into each bracket on the back of the One-Piece unit, insert a tamper plug.
2. Loosely place the tamper plug into the slot in the bracket.

Installation Guide: 3M™ One-Piece GPS (TD4i) Offender Tracking System and Curfew Unit
20
3. Push the tamper plug into the slot making sure to enter the right side first.
4. Secure the tamper plug by pushing the left side of the tamper plug into the slot.
4.5 Preparing the Strap
Before attaching the One-Piece unit to the offender’s ankle, you need to prepare the strap. Preparing the
strap involves the following actions:
Measuring and cutting the strap to fit the size of the offender’s ankle.
Installing the pin-trays.
To prepare the strap:
1. Examine both ends of the strap and check that the strap has been cut
evenly. If the strap has been cut at an angle or the fiber optic cable is
protruding, proceed with step 2. If both ends are cut evenly move to
step 3.

If using a reinforced strap, make sure that the copper wire is cut evenly and is not protruding
from the strap.
2. Spread the handles of the strap installation tool and insert the uneven end of the strap into the
measuring slot. Push the strap in until the edge of the strap is at the edge of the slot. Squeeze the
handles together to cut the end of the strap. Keeping the handles together, tilt the strap
installation tool, and tap out the cut piece of strap.
3. Spread the handles of the strap installation tool and insert the pin tray into the slot located on the
handle. Push the pin tray in until it stops.
Note that the metal pins should be facing upwards and the silicone plug should be under the lip of
the slot.
4. Lay the strap installation tool in the palm of your hand. Place the strap over the pin tray and ensure
that the end of the strap is touching the lip of the pin tray slot.
5. Squeeze the handles together until the strap is firmly attached to the pin tray.
