Backup Battery
The MT 3060 comes with a backup battery installed. The battery is a 230 mAh rechargeable Lithium-ion.
The primary function of the backup battery in the MT 3060 is to provide enough power to allow
notification to a user when there is a loss of power to the device. Power loss can indicate device
tampering or battery disconnection or removal.
You can use Input Event 63 to trigger an output event that can be configured in the same manner as
the other output events. If the modem is off (to save power), this event is turned on. If GPS data is
configured in the output event and the data is not available, the last known position can be configured
to be used in the output message.
You can use AT$OBDBBT to configure the time (in seconds) that the device stays powered after removal
from the vehicle. The range is 30 to 6000 seconds with the default being 600. In addition, to prevent
damage to the battery, the device turns itself off when the battery reaches the level determined to be
the lowest “safe” value.
If the configured output message has not been sent when the timer or battery level dictates that the
device should shut down (and is configured to do so), the message is saved and sent the next time the
device registers on the network.
