Consider device compatibility
If you have a pacemaker or hearing aid, check with your doctor to make sure it is safe for you to use a cell phone.
In some cases, cellular radio frequencies can disrupt the performance of other electronic equipment. If you
have questions about the interaction between your phone and any other piece of electronic equipment, ask the
equipment manufacturer.
Drive safely
When you are driving, we encourage you to use your phone in a safe and sensible manner. Here are a few tips:
• Assess road conditions before answering your phone. Your safety is more important than any call.
• Prepare your hands-free headset, if you have one, or turn on your speakerphone, before you
start moving.
• Keep your phone close. If it rings and you discover it's in the back seat, do NOT crawl over the seat to answer it
while driving.
• Pre-program frequently used numbers into your phone for easy, one-touch dialing.
• Remember that laws prohibiting or restricting the use of a cell phone while driving may apply in your area.
