3.2 Switches
3.2.1 Push To Call (PTC)
The Push To Call (PTC) switch allows the user to place a call to a number that has been
programmed, such as the concierge service. 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 Page 6

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 Mini-
MT device.
GSM2228AN001 Page 7

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 built-
in 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 Page 8

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 Page 9

6 Mini-MT 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 Mini-
MT 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-To-
Call (PTC) button is pressed.
To configure the Mini-MT to call phone number “1-214-555-1212” enter the following
command:
AT$DSPATCH=“12145551212” <Enter>
After entering the dispatch number enter: AT&W <Enter> to save. This will ensure that
if the battery is removed the number will not need to be re-entered.
6.2 SMS Destination
The SMS Destination Address is where the Mini-MT would send an SMS text message.
The Mini-MT can store up to five (5) SMS Destination Addresses. The following
example shows how to set an SMS Destination Address:
AT$SMSDA=1, “19875551212”<Enter>
GSM2228AN001 Page 10

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$SMSDA field. (Messages and alerts can also be sent via GPRS packet data. The
user has the ability to control the IP and port that the packet data is transmitted to)
The factory default configuration of the Mini-MT will not have any SMS Destination
Addresses configured and will not be capable of generating SMS messages for Geo-
Fence events.
6.4 User-Defined button(s)
6.4.1 User-definable Button “”
The Mini-MT “” button is user-definable through the event engine. The default state
is to configure a ½ mile radius geo-fence at the current location.
6.4.2 User-definable Button “>”
The Mini-MT “>” button is user-definable through the event engine. This button
function is not defined from the factory.
6.5 Setting the Emergency Call number
The Mini-MT is capable of dialing an emergency number (AT$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” <enter>
AT&W <enter>
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 Page 11

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.
