● Park/Geofencing Protection

．There are two methods to activate WebTrac-4S Parking mode.

Mode 1:

You can press the “Park” button on the WebTrac-4S when leaving a vehicle. After the park function is activated, it

will have three buzzes for noticing user that it’s in the parking mode. After that, WebTrac-4S will suspend the auto
report function. If it is in the GPRS coverage then it will upload a confirmation data to either the assign IP/domain or
the E-mail address. If the GPRS is not available, it will send a SMS to the first numbers in the contacts list instead.
While the GPS is not fixed, you will not be able to activate the Park function, and it will have two buzzes to alert
you.

Mode 2:

You can use any cellular phone to send a SMS message for activation (Please check the sub-chapter 5.7 for more
information). After the park mode is activated, WebTrac-4S will stop the auto report. It will send a confirmation
SMS back to the cellular phone. At the same time, it will also upload a confirmation data to the assigned IP/domain
or the defined E-mail address. If the GPRS is not available, it will send a SMS to the first numbers in the contact list
instead. While the GPS is not fixed, Park function is not allowed.

． When WebTrac-4S has been moved from the original place and its speed is more than certain nautical miles/hr (it’s

adjustable, see chapter 5.11 for further information, the default is 5 knots/hr), it will send the “Move” message
containing GPS position to either the URL or 1

st

predefined number depending on the availability of GPRS. The

interval is 60s and the total amount of data sent will be 60.

． Both pressing the button again and sending a “Park” command can deactivate the Park function, when press the park

button to deactivate the parking mode it’ll sound one buzz to notice you. When the parking mode is deactivated, auto
report will be restarted if the monitor had set the auto report function before.

． Once GPS could not fix a position and the u ser tries to activate the Park function, WebTrac-4S will reply a failure

message to the commander.

． Park function will not be allowed once the Panic is activated.

● Voice

．You can setup both dual-way communication or one-way co mmunication to converse to the user or monitor. In the

dual-way communication, the user has to insert the headset to the headset plughole in order to know if there’s anyone
calling him/her. In the dual-way communication, press park button to answer the phone, hung it up by pressing park
button again. Otherwise it’s going to wait for few seconds and pick up the phone automatically. Please note that, if the
call is picked up automatically, pressing park button is not going to hang up the phone.

．You can also set it up to one-way communication. When the monitor dials its number. It’ll pick up the phone

automatically without user’s consciousness in order to understand the user’s surrounding.

．The user is unable to use this device to call out.

．The sensitivity of the hidden microphone is -24 +/-3dB. It is simply able to receive the voice with normal speaking

volume within the range of 3m~5m.

Start Programming WebTrac-4S

Use your cell phon e to send a message as below to WebTrac-4S to obtain the Imei code for logon on our website in order
to read the GPS position on Internet (please see 5.14). This is also helping you to verify if the WebTrac-4S is correctly
functioning.

＃Username，0000，Imei＊

If the command has been transferred successfully, WebTrac-4S will send an imei code to your cell phone otherwise a
failure message will be sent instead.

Then send a SMS messages (the format is seen below) to set up the APN (Access Point Name) that is provided by your
GSM provider. The default APN is only applicable for the users in Taiwan. If you don’t know what your APN is, please refer to
chapter 8 for the APN table or contact your local mobile phone service.

＃Username，0000，3，your APN，user，password＊

After sending the SMS command, WebTrac-4S will response a message to your cell phone to see if the WebTrac-4S does
receive the command. Please note that the WebTrac-4S is not able to determine the validity of the APN

.

Use your cell phone to send a SMS command seen below to predefine a cell phone number into WebTrac-4S.
＃Username,0000,5,cellular phone number*

After sending the SMS command, WebTrac-4S will response a message to your cell phone to see if the setup is successful

.

When either APN or URL is incorrect or GPRS/URL is not available, the WebTrac-4S will not be able to upload the data
to the website. In any case mentioned above, the WebTrac-4S will send a SMS instead containing GPS position to the 1

st

predefined number after 5 failed tries on uploading the data. Please refer to chapter 5.8 for more information about
predefining phone numbers.

Next, send a message as below to WebTrac-4S to program the regular auto-report, WebTrac-4S sends a report every
minute for 99 times.

＃Username，0000，6，60，99＊

After sending above SMS command, the WebTrac-4S will also send a confirmation message to your cell phone to see if
the setup is successful. If both APN and Auto Report are setup successfully, you should be able to read the GPS
information from our website by proceeding the next step. If only the Auto Report and predefining number (5.7) setups
are successful, you will not be able to read the GPS position on our web page provided. Instead, you should have a SMS
after about 7 minutes.

Chapters 6 Respond SMS messages

This chapter shows you how to read and understand the different response messages sent from
WebTrac-4S. When WebTrac-4S is in GPRS/SMS mode it will upload the data to the assigned URL first.
However, if GPRS service is not available, it will send the SMS to the predefined phone number instead.
In the case of GPRS-only mode, WebTrac-4S will only send the data by GPRS no matter there is GPRS
service or not. Basically, there’re 7 different situations that trigger the WebTrac-4S to response its
position (Auto Report, Polling, Emergency, Park, Un-park, Move, Low Power) and are shown in the
following pages.

Event Table:

This event table helps you to know what event triggers the response.

Event Descriptions

Auto

When the monitor sends a valid Auto Report command to WebTrac-4SS, it will send a report including
an “Auto” behind each GPRMC sentence.

Park

When either pressing the Park button or sending a SMS to the WebTrac-4SS activates the Park mode,
the WebTrac-4SS will send the information (GPS position) containing a “Park” behind each GPRMC
sentence. And the previous Auto Report mode, if there is any, will be substituted.

UnPark

When either pressing the Park button or sending a SMS to the WebTrac-4SS again deactivates the Park
mode, the WebTrac-4SS will send a report including a “Un-park” behind each GPRMC sentence. If the
monitor has defined any Auto Report previously, the WebTrac-4SS will recover the Auto Report mode
and execute it from where it stopped.

Move

When the WebTrac-4SS is in Park mode and it was moved with the speed of more than certain speed
( it can be adjustable, the default is 5 knot/hr, please see chapter 5.11 for further information) , it
will send a report including a “Move” behind each GPRMC sentence. The interval is 60s and a total of
60 reports will be uploaded to the URL. Meanwhile, if the monitor sends Auto Report command, it will
only update the previous Auto Report parameters and the “Move” mode will not be stopped unless
sending it another Park command to un-park.

SOS

When the user presses the Panic button, it will send the report including an “SOS” event behind each
GPRMC sentence. No configuration is allowed in SOS mode. The SOS mode will only be released by
special commands (Master Reset and Off Panic) and switching it off/on.

LP

When WebTrac-4SS detects its battery ‘s voltage is lower than certain level, it will send a message to
the 1st predefined number. The event is “LP” that means low power. When receive this message, please
recharge the wevtrac-4.
