The MTB500 is a powerf l GPS locator designed for fixed asset tracking
applications. MTB500 work with two CR123A Lithi m-batteries. MTB500 wakes p
every 1~40ho rs and send the info and then ret rn to deepsleep. MTB500 can
standby 1000days. With b ilt-in motion sensor, MTB500 can also detect the motion
of asset all the time and give a warning message. Based integrated@track protocol,
the MTB500 can comm nicate with a backend server thro gh the GPRS/GSM
network to transfer reports of emergency, geo-fence bo ndary crossings, low battery
or sched led GPS position along with many other sef l f nctions. System
Integrators can easily set p their tracking systems based on the f ll-feat red@Track
protocol.
This device complies with Part 15 of the FCC R les. Operation is s bject to the
following two conditions:
1. This device may not ca se harmf l interference.
2. This device m st accept any interference received, incl ding interference
that may ca se ndesired operation.
Ord.code.: MTB500
