Q: You can open a blank message to test this. If your phone starts predicting the word you're typing as you hit buttons, T9 is already on and you're all set! If not, your phone is set to the multi-tap method, and you'll need to turn on T9. Check your "Settings" or "Options" you may have to explore your phone a bit to figure out how to do this. As you can see, each number on the keypad has three or four letters on it. For example, the number 2 has "ABC," the number 3 has "DEF," and so on. Familiarize yourself with the keyboard, especially if you've never used it before or you're used to typing with a full keyboard. At first, you'll probably do the "hunt and peck" method to find the letters you need, but it will become second nature once you use T9 enough! It's time to practice! Use the word "HELLO" to practice. In multi-tap texting, you would need to press the 4 button twice to get to the "H," then the 3 button twice to get to the "E," and so on. With T9, you only have to press the number that the letter is on, and you do not need to double or triple press it to get to the letter you want. For "HELLO," you would only need to press 4-3-5-5-6. These are the numbers containing the letters that spell "HELLO."
A: Make sure your phone is set to T9 mode. Examine your keyboard. Open a blank text message or note.

Q: Whether the local water comes from a tap, stream, well, or another local source, it may contain bacteria. If you must drink the local water, bring it to a boil it over high heat. Keep it at a rolling boil for 1 to 3 minutes to kill off the harmful waterborne pathogens. At high altitudes, boil the water for about 3 to 5 minutes. Ask for beverages like coffee and tea that are prepared with boiling water. Pick up a packet of water treatment tablets at a sporting goods store, travel store, or pharmacy. Use iodized water filters to purify your water, or add 5 drops of tincture of iodine per 1 quart of water. Alternatively, add tetraglycine hydroperiodide tablets to your water. Follow the instructions on the packaging for correct usage. Avoid ingesting untreated water, whether it's in a liquid or solid state. Freezing doesn't kill off bacteria the same way that boiling does. Ice cubes can quickly contaminate otherwise safe beverages like bottled water. For this reason, never add ice to anything you drink. If someone puts ice in your drink, ask for a clean glass. Even if you see local residents drinking untreated water or ice, don't drink it yourself. Locals typically develop immunity to the bacteria. Don't drink beverages mixed with local water or ice such as locally-made fruit juice or frozen beverages. Opt for canned or bottled carbonated water, still water, soft drinks, beer, or wine. Carefully inspect the seal on the container before drinking what's inside, then dry off any moisture on the outside of the container. If the beverage has been brought to you already opened, don't drink it. Carbonation kills off the bacteria, making carbonated water a safer choice than still water. Bottled and canned beverages are often stored in locally-made ice. It's essential to wipe off the container before opening it to avoid contaminating your drink. Be sure to check the seal very carefully on bottled water to make sure it hasn't been refilled with local water. This isn't an uncommon practice in developing countries.
A:
Boil untreated water for at least 1 minute before drinking it. Treat local water with iodine tablets or filters. Don't drink beverages containing ice or local water. Drink beverages after you open their original, sealed containers.
