These LawMate Covert Surveillance Glasses are extremely user friendly. Get the device operational by plugging in the mini USB into the glasses' USB Port then plug the other end into a power source. Once green LED light has turned off the device will be fully charged. While your glasses are charging format the memory card on a computer, set the date and time stamp by creating a text file and saving it into the root directory. After fully charged, insert the included micro memory card into the slot with your hand (use the provided tweezers to remove.) Power on and automatically begin recording with one long touch on the side of the glasses. A long vibration indicates the recording has started. Power off by the same button, two short vibrations will indicate the device is powered off. If the LawMate Covert Glasses don’t have a memory card, it will vibrate 20 times and power off. If memory card is full, it will vibrate 5 times and power off. When the memory card becomes full the LawMate Covert Glasses will shut down by itself. When the battery is low it will vibrate 3 times. Download data by connecting the glasses with the mini USB cord to a computer.
