Regulatory Information
Human Exposure Compliance Statement
Pursuant to 47 CFR § 24.52 of the FCC Rules and Regulations, personal communications
services (PCS) equipment is subject to the radio frequency radiation exposure requirements
specified in § 1.1307(b), § 2.1091 and § 2.1093, as appropriate.
The HT-4212/TT-4212 is designed for and intended to be used in fixed and mobile
applications. “Fixed”means that the device is physically secured at one location and is not
able to be easily moved to another location. “Mobile”means that the device is designed to
be used in other than fixed locations and generally in such a way that a separation distance of
at least 20 cm is normally maintained between the transmitter’s antenna and the body of the
user or nearby persons. The HT-4212/TT-4212 is not designed for or intended to be used in
portable applications (within 20 cm of the body of the user) and such uses are strictly
prohibited.
To ensure that the HT-4212/TT-4212 complies with current FCC regulations limiting both
maximum RF output power and human exposure to radio frequency radiation, a separation
distance of at least 20 cm must be maintained between the unit’s antenna and the body of
the user and any nearby persons at all times and in all applications and uses. Additionally, in
mobile applications, maximum antenna gain must not exceed 3 dBi.

1System Overview
1.1 Overview
The purpose behind a fleet management system is to be able to remotely review an asset,
determine its location or status, and run activity reports and alerts. This management could
include displaying the vehicle location on a map, performing an address look-up, monitoring
assets and equipment outfitted to monitor daily, weekly and monthly activity.
These functions, of course, are completely dependent on the capabilities of the NexTraq
GPS Fleet Tracking platform. The role of the NexTraq HT-4212/TT-4212 is to deliver the
relevant information when it is needed.
A typical fleet management system based on a NexTraq device includes the following
components:
An active GPRS/GSM wireless data network subscription
An HT-4212/TT-4212 device (also referred to as the NexTraq device)
NexTraq GPS Fleet Platform mapping and reporting software

1.4 Plan The Installation
Verify Power, Ground and Ignition. Be sure to check each source (power, ground and
ignition) to ensure that the proper signaling exists. This is typically accomplished with a
multi-meter.
Before drilling any holes or running any wires, decide where each NexTraq device will be
located. Be sure that the cables to the NexTraq device are not bent or constricted in any way.
Also make sure that the NexTraq device is kept away from direct impact by harmful objects
on a frequent basis and is not submerged in water or any other liquid.
Be advised that an installation that violates the environmental specifications of the NexTraq
device will void the warranty.
The best way to ensure a trouble-free installation is to consider your options and make some
decisions before you start. Take a look at the asset and determine how to best install the
NexTraq device for the following purposes:
Accurate data gathering and how you actually use the solution
Ongoing monitoring and maintenance of NexTraq device location on the equipment
Accidental or intentional alteration of the equipment or cable connections
The following sections cover some of the issues to consider when planning your NexTraq
device installation.
1.4.1 Size and Placement of HT-4212/TT-4212 DEVICE Unit
The dimensions of the NexTraq device should be taken into account:
Be sure the NexTraq device will fit before drilling any holes or running cable
Be certain that the cables running to the NexTraq device will not be bent or
constricted. Damage to the cables may impede the NexTraq device’s performance.
Be certain that the installation point will not violate any of the NexTraq device’s
environmental specification (temperature, moisture, impact, etc…) as improper
installation of the NexTraq device may void the warranty.
We suggest that the device be placed with the best view of the sky possible so that
allow maximum GPS reception and radio communication capability. Do not place
the device inside of a metallic structure or enclosure like an engine compartment.
1.4.2 Protection from Excessive Heat
It is best not to place the NexTraq device unit in an unusually hot location such as directly
near hot engine components. The maximum temperature that can be tolerated by the
NexTraq device is described in the HT-4212/TT-4212 Environmental Specifications
section.

1.4.3 Visibility of Diagnostic LEDs
Status LED lights on the front of the NexTraq device unit can provide valuable information
about the operation of the NexTraq device. When feasible, attempt to install the NexTraq
device in such a way that these lights can be seen with reasonable ease.
You may find it useful to be able to view the LEDs periodically to make sure that the HT
DEVICE is operating properly. If at any time you should encounter a problem with the HT
DEVICE, you may need to read the LEDs in order to troubleshoot the problem. If you
cannot fix the HT DEVICE yourself, you will need to provide the LED information to
NexTraq customer support.
For information about how to interpret the LEDs, see the Status LED Behavior section.
The only sequence of flashing that indicates a problem is 4 blinks per second On/1 second
Off. The orange light will always outshine the green light if both are on constant (both GPS
and radio are connected).

1.4.5 Cable Length
The cables which are provided for connecting to the NexTraq device should be used at the
complete length provided. Do not cut cables. Instead, coil any excess cable length, making
sure not to crimp or flatten the antenna cable.
1.4.6 Moisture and Weather Protection
When determining the location of the NexTraq device unit, the device must be protected
from and not be exposed to severe moisture impact. Examples of moisture impact include a
direct blast from a pressure washer or immersion in water or other liquids.
1.4.7 Preventing Accidental or Unauthorized Modification
If you anticipate that equipment operators or others might interfere with the installed
NexTraq devices, take steps to prevent easy disconnection of the wiring or easy removal of
the NexTraq device from its mounting and power source.

1.5 Installing the HT-4212/TT-4212 DEVICE on an Asset
This section provides instructions for installing an NexTraq device in a vehicle.
When you are ready to begin installing the NexTraq device, follow these steps:
1.5.1 Connect power, ignition, and ground.
The power input (red wire) must be connected to a constant (un-switched) +6-32 VDC
supply; preferably, connected as close as possible to the vehicle battery terminal. This
connection point should be fuse protected to not more than 5 Amps.
The ignition input (white wire) must be connected to the vehicle ignition or another
appropriate key operated line ensuring that power to the ignition wire is available only when
the vehicle ignition is on.
The ground line (black wire) must be connected to clean / unpainted chassis ground.
NOTE: Failure to connect these lines in the manner described may result in
discharge of the vehicle battery.
For best results, it is strongly recommended that the HT-4212/TT-4212 connection be on
its own circuit. Connect the power input directly to the vehicle battery if possible and
protect the circuit with an inline fuse. If you must connect through the fuse box, use
standard commercial wiring practices to create a permanent installation rather than using
press-in fuse clips or other temporary measures.
DO NOT connect the power cable to the NexTraq device at this time.
1.5.2 Placement of the HT-4212/TT-4212 device.
The HT-4212/TT-4212 must have a clear view of the sky. Make sure that there are no
obstructions close to the antenna that might block sending or receiving signals.

Comm Verification
Installers should first verify that the HT-4212/TT-4212 has been acquired and has registered
to the wireless network. This may be verified in one of two ways. First, installers may look at
the Comm LED (Orange). If this LED is solid, then the NexTraq device has registered to
the network and established a data session.
Please note that it may take several seconds for the HT-4212/TT-4212 device to
communicate with the modem and acquire the wireless network.
1.5.3 GPS Verification
Installers should next verify that the GPS receiver is seeing enough satellites to obtain a valid
GPS position. Again, installers have two choices on how to perform this verification. First,
like the Comm Verification, there is a GPS status LED (Green). If this LED is solid, then
the NexTraq device has found GPS service.
For further troubleshooting, installers should contact NexTraq Support by email
([email protected]m)or phone at 855-358-6178 or 678-762-6850.
