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 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)
The SIM card is not provided with the Mini-MT device. The SIM must be obtained from the GSM/GPRS service provider and
Note:
!
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.
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.
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$DSPATCH=“12145551212” <Enter>
After entering the dispatch number enter: AT&W <Enter> to save. This will ensure that if the battery is removed the number will not need to be re-entered.
6.2 SMS Destination
The SMS Destination Address is where the Mini-MT would send an SMS text message. The Mini-MT can store up to five (5) SMS Destination Addresses. The following example shows how to set an SMS Destination Address:
AT$SMSDA=1, “19875551212”<Enter>
