1. Introduction
The GL320M Series is water resistant GPS trackers designed for lone worker, vehicle, pet and
asset tracking applications. The thumb sized button makes the series ideal for applications
requiring rapid emergency alert or setting of Geo-fences based on current locations. The built-in
GPS receiver has superior sensitivity and fast initial positioning. The LTE allows the GL320M
location to be monitored in real time or periodically tracked by a backend server or other
specified terminals. The built-in 3-axis accelerometer allows motion detection and sophisticated
power management algorithms extend battery life. System integration is straightforward as
complete documentation is provided for the full featured @Track protocol. The @Track protocol
supports a wide variety of reports including emergency, Geo-fence boundary crossings, low
battery and scheduled GPS position reports.

5. Getting Started
5.1. Battery Charging
1. Connect AC-DC power adapter to GL320M.
2. Insert the AC-DC power adapter into the power socket.
3. During charging, the PWR LED flashes fast. When the battery is fully charged, the PWR
LED will be always on.
4. You can also charge the battery via USB cable which connects GL320M to the PC.
5. Charging time is about 3.5 hours.
Note:
Before using GL320M for the first time, please fully charge the battery.
5.2. Turning On/off the Device
To turn on the device:
◆Method 1: Press the Power key at least 3 seconds and then release it to turn on
GL320M. At the same time, PWR LED will also turn on.
◆Method 2: Connect the device to the charger or external battery. The device will turn
on automatically, and PWR LED will also turn on.
To turn off the device:
◆Method 1: Press the power key about 2 seconds. PWR LED will flash fast and then turn
off. It indicates that GL320M is turned off. The time needed to power off the device
depends on the quality of the network. The maximum time needed for power off is 90
seconds. This method is only valid for turning off the device when internal battery is
used. Please note the end-user cannot power off GL320M through Method 1 when the
power key is disabled by Protocol.
◆Method 2: If external battery is used, the device will power off when the external
battery is disconnected.
