power on the device. Charge the device for 3–4hours before using it.

engine of the car is not started. So please start your car to power the
cigarette lighter socket.
Get started
After inserting to the cigartte lighter socket, three operations
will happen at the same time:
1. After inserting the device there is a short "beep". The device is
ready for operation and can receive the command from the remote
control.
2. You have to pair the device with the included remote control once
to be sure that the remote control is only paired with your car alarm.
This is only possible in the first 5 seconds after you plugged the
device into the cigarette lighter socket. Press the button on the
remote control shortly until you here 4x "beep". Now the remote
control is paired with your car alarm.
Each additional remote control is paired exactly the same way.
3. The red light of the device inside the dome turns on. It indicates
the battery is charging (Charging current 65mA). The red light will
turn off when the device is fully charged.
