4.6 Tracking/Monitoring TR-151A by GPRS
Users can make commands to TR-151A for asking immediate report, periodical report, or stop
report via GPRS server and network.
Report type
Format Note Example
TR-151A will
return
0 Immediate report $0,IMEI! *note1 $0,355632000166323! $OK!
1 Period report $1,IMEI,sec! *note2
sec= 5~86400
$1,355632000166323,30!
Report every 30 seconds
$OK!
2 Stop connect $2,IMEI! *note3 $2,355632000166323! $OK!
*note1: When TR-151A receives this command, it will send the report back immediately. It will send only one time,
and the GPRS connection is still on.
*note2: When TR-151A receives this command, it will send back the report every specified second. And the GPRS
connection is still on. The time error of return could be 1~3 seconds, or larger if the GPRS connection is not stable.
*note3: When TR-151A receives this command, it will disconnect from GRPS and go to standby mode.

4.7 Displaying the location on map
The format of longitudes and latitudes got from TR-151A differs from the format of Google map/earth’s
longitudes and latitudes. So users have to convert the format of longitudes and latitudes got from
TR-151A into the format Google map/earth’s longitudes and latitudes before displaying the location on
map.
The format of longitudes and latitudes got from TR-151A is like E2459.79 and N12129.26. E2459.79
means E24°59.79’. N12129.26 means N121°29.26’ Please take the digits at the right side of the degree to
be divided by 60. The number you get is the number at the right side of decimal.
For example, the longitudes and latitudes got from is E2459.79 and N12129.26
You have to take 59.79 ÷ 60 =0.9965 ; 29.26 ÷ 60=0.487666 0.4877≒
Then you can enter 24.9965 and 121.4877 into Google earth or Google map to display the location.
● Start the Google Earth software.
Input the latitude and
longitude The Google Earth will
display the location
map for you.
TR-151A page 34
● Or you can start the Internet Explorer and type "http://maps.google.com" to connect to Google Map
website for displaying the location map.
Select "Satellite" or
"Hybrid".
It depends on Google
Map whether your
area is supported by
this mode or not.
Input the latitude
and longitude
and click on
Search button.
The Google
Map will
display the
location
map for you.

Note 1:
The format of Google map/earth’s longitudes and latitudes differs from the format of TR-151A’s.
So please convert the format of Google map/earth’s longitudes and latitudes into the format of
TR-151A’s longitudes and latitudes before setting Geofence.
If you get a set of latitude and longitude from Google earth like 24°59’47.40” & 121°29’15.72”,
you have to convert the format to TR-151A format as below and then set geo-fence.
47.40 ÷60=0.79 15.72÷60=0.262
Please take E 12129. & 262 N2459.79 to set geo-fence
If you get a set of latitude and longitude from Google earth like 24.9965°& 121.4877°, you have
to convert the format to TR-150 format as below and then set geo-fence.
0.9965 x60=59.79 0.4877 x60=29.262
Please take E12129. 262 & N2459.79 to set geo-fence
Note 2:
User can set up to 10 rectangular or circular boundaries. Each SMS contains one boundary setting.
User can send numerous SMS to complete one set of settings, including numerous rectangular or
circular boundaries. For example, if user wants to set the boundary includes 2 rectangles and 1 circle.
User has to send 3 SMS, two with rectangle information, one with circle information.
SMS1:

If user uses numerous SMS in one setting, the IMEI, In_or_Out, Report_Interval, Number_of_Reports,
Report_Format, Return_Phone_Number must be the same between each SMS. If above parameters
are not the same between SMS, TR-151A only follows last SMS.

Federal Communication Commission Interference Statement：
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 a particular 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.
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.

IMPORTANT NOTE：
FCC Radiation Exposure Statement：
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users
must follow the specific operating instructions for satisfying RF exposure compliance. To maintain compliance with
FCC RF exposure compliance requirements, please follow operation instruction as documented in this manual.
“For body worn operation, this Tracker has been tested and meets FCC RF exposure guidelines when used with
an accessory that contains no metal and that positions the device a minimum of 1.5 cm from the body. Use of other
accessories may not ensure compliance with FCC RF exposure guidelines.”
Radio wave exposure and Specific Absorption Rate (SAR) information：
This mobile Tracker (model number TR-151A) has been designed to comply with applicable safety requirement for
exposure to radio waves. This requirement is based on scientific guidelines that include safety margins designed to
assure this safety of all persons, regardless of age and health.
The radio wave exposure guidelines employ a unit of measurement known as the Specific Absorption Rate, or SAR.
Tests for SAR are conducted using standardized method with the phone transmitting at its highest certified power
level in all used frequency bands.
While there may be differences between the SAR levels of various phone models, they are all designed to meet the
relevant guidelines for exposure to radio waves.
The highest SAR value for this model phone tested by DASY5 for use at the ear is 0.699 W/kg.
SAR data information for residents in countries/regions that have adopted the SAR limit recommended by the
Institute of Electrical and Electronics Engineers (IEEE), which is 1.6 W/kg averaged over one (1) gram of tissue.
