your USB cable, you can replace it with any common “USB Mini B” data/charging
cable.
Please see the accompanying “Light Show Conguration Guide” to congure your
Tazer DT’s light show options in ZPU
You should Unmarry and remove your Tazer before dealer service
or if you wish to use your Tazer in another vehicle.
