We hope that you are never in a position where you actually have to use your stun gun but if you are, we are glad you have it to protect yourself. To use the stun gun, push the “ON/OFF” switch up into the “ON” position. You will know it is “ON” because a red light will appear and indicate that the device is in “Ready to Fire” mode. Make sure to have the top portion of the device, where the two metal prongs are, pointed at the attacker. Keeping your fingers clear of the top portion and prongs you should then activate the stun gun by pressing the black button above the red light. You will hear a loud crackling/popping noise and an electric arch will appear between the two prongs. Again, make sure to come in contact with the attacker when activating the stun gun.
