GT3088 USER GUIDE (Full Functions)
1. GT3088 Features
Designed to survive in the harshest conditions, delivering regular and accurate location records
using state of the art GPS over the cellular network, the GT3088 delivers superb performance less
expensively than ever before. Built to exacting specifications, the GT3088 is weatherproof and
durable. With the built in super-magnets in the case, the GT3088 requires over 50 pounds of direct
lift to be dislodged from any ferrous surface, making it an ideal manager for remote, and
un-powered installations such as heavy construction equipment, RV’s and vehicles of all
descriptions. With its super-magnet case, the GT3088 can be installed under a vehicle for a quick
and accurate covert tracking installation.
Flexible in its programming options, the GT3088 can be easily reprogrammed via SMS by the user
to set and reset it’s scheduled and motion detected location reporting. The GT3088 also supports a
deep sleep function, and with its internal 8800mAh rechargeable Lithium-Ion battery, can wait for
months in a true “sleeping standby” for motion or vibration to wake it into pre-programmed periodic
location reporting when it starts moving.
