3) Recharge the external battery as described below.

4.3 External Battery Charging

A fully charged external battery will allow approximately twelve to twenty-four hours of passive operation. (This

is highly dependent on GSM signal strength, sleep modes enabled, amount of messaging traffic, and internal

battery charge level).

There are two indicator lights on the charger: power and charging. When the power cord is plugged into the

wall outlet and the charger, the power indicator will light. When the external battery is then placed into the

charger, the charging indicator will light (may not light if battery is fully charged). Once the external battery has

finished charging, the charging indicator will blink until the battery is removed.

NOTE:

1) A fully discharged external battery can be fully charged by the charger board in under two hours.

2) The internal battery has limited operating time (approximately 2 hours).

4.4 Automated GPS Location and Alarm Messages

The unit automatically generates autonomous messages to the gateway to indicate the units current status and

location. Alarm messages are attempted to be sent to the server as they occur, with a retry mechanism in place

(100 messages maximum queue length). Events are also logged to the internal audit log for retrieval at a later

date, if necessary.
