REGULATORY COMPLIANCE
CC
The modem was tested and certified to meet FCC Parts 15 in a stand-alone configuration, which demonstrated that the
GSM2338 Nitro complies with Part 15 emission limits. FCC Part 22 & Part 24 is co ered by the Enfora Enabler IIIG “modular
appro al” process for a transmitter. This approach, described by FCC Public Notice DA 00-131407 released June 26, 2000, is
intended to afford relief to equipment manufactures by eliminating the requirement for obtaining a new equipment authorization
for the same transmitter when installed in a new de ice.
In order to use the GSM2338 Nitro without additional FCC certification appro als, the installation must meet the following
conditions:
For the transmitter to meet the MPE categorical exclusion requirements of 2.1091, the ERP must be less than 1.5 watts for
personnel separation distance of at least 20 cm (7.9in). Therefore the maximum antenna gain cannot exceed +3.3dBi. If greater
than 1.5 watts exists, then additional testing and FCC appro al is required.
R&TTE -
The GSM2338 Nitro modem has been fully tested and complies with all the requirements of EN301 489-1, EN301 489-7 and
EN60950-1:2002. Compliance to EN301 511 has been demonstrated by testing on both the GSM2338 and the integrated
GSM0308 module.

Table 1 – Battery Specifications
The features of the battery include the following:
•O erload protection
•Temperature sensing (will disconnect charging if out of temp range, 0° - 45°)
•Battery identification (pre ent user from trying to power the unit with an
unauthorized battery, or charge an unauthorized battery).
5Installation
Instructions pro ided in this section describe the hardware installation of the Selftrack
Nitro de ice. To install the Nitro in a ehicle, follow these steps:
•Choose a con enient location in the ehicle – either in the trunk or interior of
a ehicle. A oid locations that might expose the de ice to excessi e heat or
moisture.
•Hold the Nitro in the selected place and mark the location for mounting
screw holes. Using the markings as a guide, drill mounting holes in those
positions. Align the Nitro in the drilled holes and secure it with mounting
screws.
Warning: The Nitro is NOT a waterproof or sealed de ice. Care must be taken to ensure the de ice
is kept away from water or any other liquids.

5.1 Mounting Dimensions
It is possible to mount the Nitro using either screws, or plastic mounting rails with tie-
downs.
igure 3 - Mounting Dimensions
Alternati ely, the de ice may also be secured with the use of “sticky putty” or similar
material, pro ided it is strong enough to be held in place without coming loose due to
ibration (especially when used in hea y ehicles and off-road equipment).
6Cables and Connections
igure 4 - 8 Pin Connection
6.1 Connecting the GSM/GPRS Antenna
The antennas are designed for the frequency band in which the Nitro is going to operate.
The antenna jack is a standard FAKRA Bordeaux Violet connector.
NOTE: The antenna must ha e a nominal impedance of 50 Ohms. The VSWR must be less than
2.0:1. System antenna gain should be 0-2 dB optimum performance.

Attach the GSM/GPRS antenna to the GSM jack.
igure 5 - GSM/GPRS Antenna
6.2 Connecting the GPS Antenna
The Nitro has the capability of pro iding 3.3V to power an Acti e-Style GPS antenna.
The GPS antenna connector on the Nitro model is a FAKRA Blue connector. The GPS
antenna must be placed facing upwards in an area where it can ha e direct iew of the
sky.
The Nitro Antenna Connector supplies an acti e antenna between 2.9 and 3.3 Vdc
depending upon the load presented by the acti e antenna.
When the load exceeds the supply’s limit (o er current) it will shut off or reduce the
power a ailable to the external GPS antenna.
The Nitro’s internal 3.3 V supply pro ides antenna power ia a 10 Ώ series resistor.

N
ote:
Your de ice has already been equipped with a
SIM card. The SIM
is/
must be pro isioned for
GPRS and/or oice, and the PIN is/must be disabled. Always take care to protect the SIM. Without
the SIM installed, the Nitro modem is limited to emergency oice communication only. Please always
ensure the SIM lock is ON in order to pre ent accidental remo al.
If it becomes necessary, insert the SIM as per the following procedure:
The SIM Lock Switch is used to ensure the SIM remains in position, but also acti ates
the battery circuitry (if applicable).
Insert the SIM into the SIM Slot with the notch going into the slot first, and facing toward
the left side of the Nitro.

6.4 Power Cable Installation
Install the power cable as described in the following procedure:
igure 8 - Power Cable Installation
i. Hook up the Nitro to a 7 to 40 Vdc power source and apply power.
ii. The GPS Power LED should be solid red and the User 1 LED start
blinking green.
iii. Once the Nitro attaches to the GSM network, the User 1 LED should go
solid green. If the User 1 LED stays blinking, then there is a problem with
the SIM or cellular reception.
i . Once the Nitro acquires a GPS fix, the User 2 LED will be solid red.
6.5 Connecting the Power Source
The GSM/GPRS Nitro has an input oltage range of 7 – 40 V DC. The power and
ignition pins can support 7 -40 V DC input oltage. The user has an option to connect
these wires depending on the desired functionality. Described below are the desired
functionality and their associated wire connecting procedure:
Warning: Use of the de ice outside of the specified oltage range may result in damage to the
de ice and/or undesirable results.
Warning: Please follow the specifications as listed in the table below. Selftrack is not liable for
damage to the Nitro caused due to user error.
Insert Power Cable pro ided

Selftrack Nitro Vehicle Tracker
User & Installation Manual
Page 12
Warning: The Nitro is designed to operate from 7 to 40 VDC. The user is responsible for ensuring
the oltage supplied to the Nitro remains in this oltage range to include transient oltage spikes and
load dump oltages. Failure to comply with this warning may result in damage to the Nitro.
•Connect the power and ground wires of the Nitro to the ehicle battery leads.
The Nitro will always remain ON as long as the ehicle battery lasts.
•The Nitro will still be operational when the input oltage and current
requirements are not met ( ehicle battery drains) since the unit is equipped
with an internal emergency backup battery.
•Connect the Ignition wire to a switched source that recei es positi e oltage
when the ignition is ON.
•De ice goes through a reset upon an ignition transition, if connected.
6.6 LED Operation
The Nitro has three LED’s on its front panel:
igure 9 – LED Operation
GPS PWR: Indicates power to the GPS module. LED is on when power is
turned on and the GPS module is operational. LED is off when
power is remo ed (and if internal battery is drained) or when the
Nitro enters standby mode.
User LED 1: This LED indicates GSM/GPRS registration status. LED state
OFF indicates that the de ice is not attempting to register to the
network. Blinking LED indicates that the de ice is trying to

Selftrack Nitro Vehicle Tracker
User & Installation Manual
Page 13
connect to the network. LED always ON indicates that the
de ice is attached to the network.
User LED 2: This LED indicates GPS registration status. LED state OFF
indicates that the de ice is not attempting to register to the GPS
network. Blinking LED indicates that the de ice is trying to
connect to the network. LED always ON indicates that the
de ice is attached to the network.
6.7 General notes on installing cables and wiring
During installation, the following precautions will help ensure proper operation of the
de ice:
•Remo e power from the Nitro.
•Do not create loops, sharp bends or crimps in the cables.
•All cables should be attached to the ehicle and equipment in such a way to
reduce stress or wear caused by ibration generated by mo ing ehicles.
•No more than a combined total of ten (10) pounds force can be applied to
the cable connectors.
•Use proper terminations on all power cables.
It is highly recommended that the white wire (ignition line) be run to an ignition switched
line that is high in both start and on positions. High is measured as at greater than 1 olt.
If the ignition sense line of the de ice is wired to a source where the oltage goes low
(drops below 1.0 Volts, e en momentarily) when in the start position, then ignition
debounce may be required, and ignition ON e ent trigger could be missed on occasion.
6.8 Standard Selftrack Nitro Installation configuration
The eight (8) pin external I/0 and power harness connector for the Selftrack Nitro is
included in the package. Table 1 below describes the pin functionality.
