Introduction

Thank you for purchasing The Diy Track Defender® vehicle tracker and alarm

The Defender

can be installed in any type or make of vehicle with a voltage range of 12-24v. However the immobiliser

Function only operates on 12volt vehicles.

Each unit has been manufactored to the highest quality to ensure reliability and ease of use.

Before Installing

This guide covers the installation of the Diy-Track device to ensure a safe and functional install of the unit by either a

professional or novice installer

Prior to the installation process, thoroughly review this guide and adhere to the following:

- Use only a Digital or Analog Volt Meter - DO NOT USE A TEST LIGHT!

- Check for possible installation locations for the tracker unit prior to permanent installation.

- Make sure that the installation process does not cause damage to any vehicle hose, electrical loom,

or cause physical damage to the vehicle.

- Make note of the unit mobile and serial numbers prior to installation.

- Prior to installing this device or working on any part of the dashboard (instrument cluster, center console, glove box, etc.),

always disconnect the vehicle battery to deactivate the sensors for the airbags and to prevent a possible voltage surge.

- Make sure the device and all associated cables are securely mounted and do not impede any of the vehicle's controls.

- Ensure all connections are properly soldered and insulated, all un-used cables must be properly insulated.

- Use high quality electrical tape and shrink tubing were necessary

- DO NOT place objects, including communication equipment, in the area over the airbag or near the airbag deployment area,

GPS Fundamentals

There is a minimum of 24 operational GPS satellites at all times. The satellites, operated by the U.S. Air Force, orbit the earth every

12 hours. Each GPS satellite transmits data that indicates its location and the current time. All GPS satellites synchronize operations

so that these repeating signals are transmitted at the same instant. The signals, moving at the speed of light, arrive at a GPS receiver

determined by determining the amount of time it takes for their signals to reach the receiver.

When the receiver determines the distance to at least four GPS satellites, it can by triangulation, calculate its position in

three dimensions.

To ensure the GPS unit receives enough satellite signals at an acceptable signal strength, the antenna must be mounted

so that it has a clear view of the sky. In hidden locations, such as under the dash, a clear view can be challenging. In these locations,

it is important to keep any metal interference as far as possible from the top of the GPS antenna so that the most accurate

position can be calculated.

While GPS data collection has improved in ease and speed, some obstacles remain. Solid or dense objects can block GPS signals.

Wet trees with heavy branches and leaves can mask or attenuate GPS signals. Mountains and buildings can block satellite transmission.

Multipath signals can corrupt GPS data. Multipath is a re ected signal from some nearby objects. The resulting propagation delay

can a ect measurement accuracy. GPS electronics advancements have reduced the multipath threat but GPS eld operators and

users should be aware of obvious multipath environments.

All GPS Trackers require a SIM card

To get the location data from the GPS tracking unit to a users computer some transmission channel is required.

The Tracker uses GPRS and only sends a very small amount of data.
