To meet GSM specification, pressing the PTC button with no SIM installed will cause the unit to initiate a “411” call. The application provider will need to configure the emergency number for its region. 3.2.2 Set Geo-Fence The switch is used to initiate a geo-fence with a default radius of one-half mile. This radius may be re-defined by the application provider and is retained in non-volatile memory. If GPS is not available an error tone will be generated to alert the user that no geo-fence was set. 3.2.3 User-Defined button The User-Defined button is a programmable button that can be defined for various functions. This button could be programmed to generate a call to a number different from the PTC button, generate a geo-fence with different parameters than the geo-fence button, send an SMS of the current location to a cell phone, send the current location to the server, etc. 3.2.4 Volume Buttons The Mini-MT has two volume buttons for controlling the audio volume level. These buttons are functional whether in a call or not. The ‘+’ button is used for increasing volume and the ‘–’ button is used for decreasing volume. GSM2228AN001 Page6 3.3 Interconnections 3.3.1 USB Connection The USB connector is used for charging the battery and for data communication. The unit will charge from a laptop computer, AC to USB power adapter, or vehicle power to USB adapter. (See Figure 3) Data communications with the Mini-MT is also performed through the USB connector. The USB connection is used to configure or customize the Mini-MT operation. This connection also is used to provide GPS NMEA data to a mapping or user application. 3.3.2 Headphone Jack The headphone jack provides the user with the ability to connect a headset (not supplied) when the speakerphone mode is not desirable. (See Figure 3) 3.3.3 Speaker An integrated speaker allows the user to make a phone call to the pre-configured dispatch number when in hands-free mode. The user can adjust the volume to a comfortable level using the volume up (‘+’) or down (‘-’) buttons. WARNING The Mini-MT is used in speaker phone or headset use only. Do not use the device held up to the head . The audio levels and SAR ratings have not been approved for use in this manner. 3.3.4 Microphone A built-in sensitive microphone allows the user to communicate with the dispatcher comfortably at up to 3 feet away for hands-free operation. 3.3.5 SIM A SIM cardholder is located under the battery on the bottom of the Mini-MT. The SIM card is required to enable the voice and data communication capabilities of your MiniMT device. GSM2228AN001 Page7 3.3.6 Battery A 1340mA/H Li-Ion battery is supplied with the Mini-MT that will allow operation without USB power. The Mini-MT battery life varies based on configuration and use of the Mini-MT. 4 Battery Removal / Insertion / Charging The Mini-MT is supplied with a 1340mA/H Lithium-Ion rechargeable battery with builtin safety features. The battery should be removed to gain access to the SIM card and for turning the unit off (shipping or travel). The battery is shipped with a protective cover over the battery terminals and must be removed before use. The following steps provide instructions for how to remove or replace a battery. 4.1 Removing the battery Access to the battery is through the battery door on the bottom of the Mini-MT. Firmly press the battery cover latch and pull the battery door open. Pull up on the battery using the thumb latch until the battery releases from the retention clips. Slide the battery away from the contacts and remove from the Mini-MT. NOTE: The battery is initially provided with a red protective cover over the terminals. Remove the protective cover by peeling off of the battery to expose the terminals. Discard the protective cover after removal. 4.2 Inserting the battery While the battery cover is removed, insert the battery into the battery compartment with the contacts aligned with the Mini-MT power contacts. The battery must be inserted into the battery compartment at a 45-degree angle with the contact end first. Ensure the contacts of the battery line up with the contacts in the Mini-MT. Push the battery in towards the contacts and then down firmly until fully seated in the battery compartment. Replace the battery access door ensuring the latch is locked firmly in place. 4.3 Charging the battery The Mini-MT must be charged for 12 hours prior to initial use. Charging your Mini-MT battery may be done using a standard USB cable (optional: CAW-6000-0006) connected to your desktop personal computer (PC). GSM2228AN001 Page8 NOTE: The PC must be turned on or powered up while charging the Mini-MT. For charging the Mini-MT battery in a vehicle an optional USB to vehicle accessory power adapter is available (PSA-9000-0002). NOTE: Many vehicles do not provide power to the accessory jack when the vehicle ignition is off. An alternate method for charging using AC power may be performed with the AC power to USB power adapter (PSA-9000- 0101). Connect one end of the USB cable to the Mini-MT and the other end to your power source. The Mini-MT ON LED will be illuminated solid and the BAT LED will flash while charging. When the Mini-MT is fully charged the BAT LED will be extinguished and the CALL LED will be illuminated solidly while connected to a USB power source. 5 SIM Card Insertion / Removal The Mini-MT requires an activated SIM card to operate on the GSM network. The SIM card is located under the battery. Remove the battery door and the battery when accessing the SIM cardholder. (See battery Insertion / Removal section of this document) Note: The SIM card is not provided with the Mini-MT device. The SIM must be obtained from the GSM/GPRS service provider and must be provisioned by the operator for data and/or voice. Always take care to protect the SIM. Without the SIM installed, the Mini-MT is limited to emergency voice communication only. Ensure the power to the Mini-MT is disconnected including disconnecting from USB cable before inserting the SIM card. Failure to do so might result in an unusable Mini-MT or a damaged SIM card. The tray has a sliding latch for retention of the SIM card. The tray must be opened before a SIM card can be inserted or removed. Slide the tray to the “unlatched” position and pivot the tray outward. Insert (or remove) the SIM card, pivot the tray back into the holder and slide the tray to the “latched” position. Care should be taken to ensure proper orientation of the SIM card in the tray before closing. GSM2228AN001 Page9 6 Configuration The Mini-MT must be configured before use. Configuration is performed through AT commands from a PC computer. A terminal program is required to interface to the MiniMT through the USB cable. HyperTerminal is a terminal program that may be supplied with your computer operating system and is used in this document for examples. The Mini-MT drivers must be installed on your computer before proceeding. Refer to Section 7: Software Installation of this document for driver installation. 6.1 Dispatch Number The “Dispatch Number” is the phone number the Mini-MT will call when the Push-ToCall (PTC) button is pressed. To configure the Mini-MT to call phone number “1-214-555-1212” enter the following command: AT$DSPATCH=“12145551212”After entering the dispatch number enter: AT&W to save. This will ensure that if the battery is removed the number will not need to be re-entered. 6.2 SMS Destination The SMS Destination Address is where the Mini-MT would send an SMS text message. The Mini-MT can store up to five (5) SMS Destination Addresses. The following example shows how to set an SMS Destination Address: AT$SMSDA=1, “19875551212” GSM2228AN001 Page10 6.3 Set Geo-Fence There are two user-definable buttons on the Mini-MT. The first button is factory defined to set a geo-fence. Depressing the Geo-Fence button will place a half-mile radius circular geo-fence around the Mini-MT. When the Mini-MT exits the geo-fence an alert message will be sent via SMS message to the SMS Destination Address defined in the AT$SMSDA field. (Messages and alerts can also be sent via GPRS packet data. The user has the ability to control the IP and port that the packet data is transmitted to) The factory default configuration of the Mini-MT will not have any SMS Destination Addresses configured and will not be capable of generating SMS messages for GeoFence events. 6.4 User-Defined button(s) 6.4.1 User-definable Button “” The Mini-MT “” button is user-definable through the event engine. The default state is to configure a ½ mile radius geo-fence at the current location. 6.4.2 User-definable Button “>” The Mini-MT “>” button is user-definable through the event engine. This button function is not defined from the factory. 6.5 Setting the Emergency Call number The Mini-MT is capable of dialing an emergency number (AT$EMERNUM) and a dispatch number (AT$DSPATCH). The default emergency number in the Mini-MT is “411.” The provider should reconfigure this number to the correct emergency number for the region the Mini-MT will operate in. To set the emergency number to “911” enter the following text in the terminal window: AT$EMERNUM=“911” AT&W The first command sets the emergency number to 911 and the second commands saves the setting in the phone to ensure it remains programmed after a master reset (battery removal). GSM2228AN001 Page11 6.6 Dialing the Emergency Call Number The Mini-MT will allow emergency communications without a SIM card installed. Initiating an emergency call is done by depressing the PTC button and the “>” button simultaneously. The ON, GPS, and BAT LED’s will flash in unison. At this point, momentarily release the PTC button and the CALL LED will flash. Re-depress the PTC button and confirm the LED’s flash in unison again. Release the “>” and the PTC buttons. The Mini-MT will establish a call to the number configured in the AT$EMERNUM command.

NOTE: Selecting the Clear button will erase the contents of the “(ASCII Data):” window. 5. Enter the following command in the Command / Data text box: ATI 6. Click on the Write button. GSM2228AN001 Page32 7. Verify that you see the following modem response showing Enfora, Inc. If so, you have successfully configured the modem to talk with the server. GSM2228AN001 Page33 8 GPS Operation and Verification The Mini-MT contains an integrated GPS receiver and GPS antenna. For best GPS performance the unit should be placed in an area where it can have direct view of the sky. 8.1 Verification of GPS Lock The Mini-MT will provide an indication of successful GPS Lock within approximately 60 seconds when in view of satellites. The GPS LED will flash yellow when it is receiving a sufficient number of satellites to provide status. When this occurs, the internal GPS receiver has enough information to track its current position. 8.2 Verify GPS operation The Mini-MT GPS status may be obtained locally through the USB connection or through the GPRS connection to a server. The following steps allow the user to determine GPS operation through a terminal program and also through the Enfora Demonstration web server. 8.2.1 GPS Operation from Terminal From the terminal window, send the following command: AT$GPSRD=10 The modem should respond with a standard GPRMC message that looks similar to the following: $GPRMC,170513.78,A,3301.465384,N,09642.417298,W,0.0,0.0,011206,,,*06 NOTE: The entry shown in bold is the current GPS status. There are three possible values here: • • • A = OK V = Warning 9 = Enfora Specific response that GPS solution is not valid and the last known GPS location is being substituted. GSM2228AN001 Page34 Here is an example of a GPRMC message without a GPS lock: $GPRMC,221553.30,V,,,,,,,,,,N*7C 8.2.2 GPS Operation from Enfora Demo Server The same command can be used in the server application by entering AT$GPSRD=10 in the Command / Data text box, then selecting Write. The following screen shot shows the command and the response: NOTE: The third field is a single character field representing the status of the GPS reading. There are three valid character for this field and are described below: • • • A = OK V = Warning 9 = Enfora Specific response that GPS solution is not valid and the last known GPS location is being substituted. GSM2228AN001 Page35 9 Safety Information for Wireless Devices 9.1 RF Exposure WARNING Please read this information before using your wireless device. Your Mini-MT is a radio transmitter and receiver. It is designed and manufactured not to exceed the emissions limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission (FCC) of the U.S. Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. These guidelines are based on the safety standards previously set by the U.S. and international standards bodies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. The exposure standard for wireless RF devices, such as the Mini-MT, employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg. SAR values at or below that limit are considered safe for the general public. Before a wireless RF device is made available for sale to the Public, it must be tested and certified to the FCC that it does not exceed the SAR limits established by the FCC. Tests for SAR are conducted using the positions and locations (e.g., at the ear or worn on the body) as required by the FCC for each device model. The Mini-MT has been tested and meets the FCC RF exposure guidelines when used as a speakerphone, with a standard 2.5mm headset, or when worn on the body using an approved belt clip. Other uses may not ensure compliance with FCC RF exposure guidelines. WARNING GSM2228AN001 To minimize RF exposure, it is strongly recommended that you use a headset with your Mini-MT or operate it in hands-free mode. Page36 9.2 Scientific evidence on RF exposure The following information, in large part, is excerpted from, or based on, information provided by the U.S. Food and Drug Administration (FDA) on its website under the heading “Cell Phone Facts: Consumer Information on Wireless Phones” (http://www.fda.gov/cellphones/qa.html). The information provided below reflects scientific evidence available through the end of 2004. Please visit the aforementioned FDA website (and the other websites mentioned below) for the latest information. The available scientific evidence does not show that any health problems are associated with using wireless phones. There is no proof, however, that wireless phones are absolutely safe. Wireless phones emit low levels of RF while being used. They also emit very low levels of RF when in the stand-by mode. Whereas high levels of RF can produce health effects (by heating tissue), exposure to low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects may occur, but such findings have not been confirmed by additional research. In some cases, other researchers have had difficulty in reproducing those studies, or in determining the reasons for inconsistent results. The FDA and other U.S. government agencies responsible for public health and safety have worked together and in connection with the World Health Organization (WHO) to monitor developments and identify research needs related to RF biological effects. It is generally agreed that further research is needed to determine what effects actually occur and whether they are dangerous to people. In the meantime, standards-setting organizations and government agencies are continuing to monitor the latest scientific findings to determine whether changes in safety limits are needed to protect human health. In 1996, the WHO established the International EMF Project to review the scientific literature and work towards resolution of health concerns over the use of RF technology. The WHO maintains a Web site that provides extensive information on this project and about RF biological effects and research (www.who.ch/peh-emf). If there is a risk from using wireless phones—and at this point the scientific evidence does not demonstrate the existence of such a risk—it is probably very small. But if you are concerned about avoiding even potential risks, you can take a few simple steps to minimize your exposure to RF. Since time is a key factor in how much exposure a person receives, reducing the amount of time spent using a wireless phone will reduce RF exposure. If you must conduct extended conversations by wireless phone every day, you could place more distance between your body and the source of the RF, since the exposure level drops off dramatically with distance. For example, you could use a headset and carry the wireless phone away from your body or use a wireless phone connected to a remote antenna. Some groups sponsored by other national governments have advised that children be discouraged from using wireless phones at all. For example, the government in the GSM2228AN001 Page37 United Kingdom distributed leaflets containing such a recommendation in December 2000. They noted that no evidence exists that using a wireless phone causes brain tumors or other ill effects. Their recommendation to limit wireless phone use by children was strictly precautionary, and was not based on scientific evidence that any health hazard exists. More recently, a report published in January 2005 by the British National Radiological Protection Board (NRPB) summarized the results of various studies from 2000 to 2004 on the effects of wireless phone use, and concluded that there is no hard evidence that the health of the public is being harmed by the use of wireless phones, but that uncertainties remain regarding the risks associated with long-term wireless phone use. Therefore, the report suggested that a "precautionary or prudent approach" to reducing RF exposure from wireless phones should be followed until more is known about these potential risks, including the potential increased sensitivity of children to RF. The report (NRPB-W65) is available for download at the NRPB website (www.nrpb.org). Again, the scientific evidence does not show a danger to users of wireless phones, including children and teenagers. If you want to take steps to lower exposure to RF, the measures described above would apply to children and teenagers using wireless phones. Specifically, reducing the time of wireless phone use and increasing the distance between the user and the RF source will reduce RF exposure. The FDA scientific staff has reviewed the methodology used by FCC to measure cell phone RF, and has agreed that it is an acceptable approach, given our current understanding of the risks presented by cellular phone RF emissions. RF emissions from cellular phones have not been shown to present a risk of injury to the user when the measured SAR is less than the safety limits set by FCC (SAR of 1.6 w/kg). The FDA will continue to monitor studies and literature reports concerning acute effects of cell phone RF, and concerning chronic effects of long-term exposure to cellular telephone RF (that is, the risks from using a cell phone for many years). If new information leads FDA to believe that a change to FCC’s measurement policy may be appropriate, the FDA will contact the FCC, and both agencies will work together to develop a mutually acceptable approach.

Page39 11 Product safety instructions Please follow all safety instruction outlined below. Failure to follow these instructions may result in serious personal injury and/or property damage. Always obey all applicable regulations in any area where the Mini-MT may be used. Turn your Mini-MT off by removing the battery in areas where its use is prohibited or where it may cause interference or danger to anyone. Use of radio equipment is prohibited in hospitals and may interfere with the use of medical equipment. Do not use the Mini-MT in hospitals or near medical equipment. The Health Industry Manufacturers Association recommends that a minimum separation of six inches (6”) be maintained between a handheld wireless device and a pacemaker to avoid potential interference with the pacemaker. When boarding a plane, follow all instructions of the flight crew on the use of wireless devices. FCC regulations prohibit using your wireless device during any air flight. Turn off your Mini-MT during flight and at all other times as requested by the flight crew by removing the battery. Do not use the Mini-MT in the vicinity of blasting areas where it might interfere with remote control RF devices used to set off explosives. Although it is rare, wireless phones can generate sparks. Do not use or store your MiniMT phone around flammable or explosive gas, liquids, chemicals or any other such materials. Certain jurisdictions prohibit the use of radio communication equipment while driving to avoid distractions and prevent accidents. Do not use the Mini-MT while driving in those jurisdictions. In those other jurisdictions where using a wireless phone while driving is permitted, use in hands-free mode, avoid using the Mini-MT in heavy traffic or hazardous weather conditions, and do not take notes, look up phone numbers or engage in stressful or emotional conversations or any other activity while driving that might divert your attention from the road.
