Turn It Off!
Have you ever seen a sign in a doctor's office or a hospital saying no cell phones can be used there? There are many places where cell phones don't belong, including, government offices, schools and library's. Please be respectful of this.
If you've been on an airplane, have you heard the flight attendant announce that all cell phones must be turned off before takeoff? Have you ever wondered why?
The signals sent by a cell phone to a tower can make the computerized machines used by doctors to stop working properly. Cell phone signals can also interfere with an airplane's computer system, which could cause serious problems.
You should never have your cell phone turned on at the doctor's office or a hospital where a sign says cell phone use is forbidden.
