After placing a call or answering your phone, simply close the shielded front cover of the DefenderShield® Cell Phone Case before you put the phone against your ear. By keeping the shielded front cover closed while against any part of your body, a barrier is created to protect from a broad spectrum of potentially harmful cell phone radiation emissions that won’t affect signal quality.

• Voice and sound quality will not be affected since the microphone is unobstructed on the bottom of your phone and a small opening over the ear speaker allows you to hear perfectly.
• When placing your phone in your pocket, purse or bag, keep the shielded front cover closed and facing towards your body.
• When using your phone’s touchscreen, flip the front cover to the back side of the cell phone.
