<Notes>
1. In a case that the device has been configured not to check MOTION. In such a case, even though any
motion is not made, the number of DISTANCE may increase little by little. In such a case, life time of the
battery could be extended. If the device is used under operation conditions having a very good
connectivity with GPS and GSM/UMTS, it can be used approximately 5 days at a reporting interval of
every 3 minutes.
2. If Field of <FIX> has <F>, there is a possibility that the GPS Module would have a problem. In such a
case, users have to contact Suntech.
3. PWR_VOLT : The percentage of the battery voltage are divided as follows:
100%, 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, 10%,
5%, 3%, 1%
