This is one of several precautions you should take before you begin tearing apart your faucet to fix a leak. You don't want to lose anything down there during disassembly! There should be two shut-off valves beneath the sink, one each for hot and cold. Turn the faucet handles to make sure both hot and cold are off, and to get rid of excess water in the lines. For mobile homes and some older homes that don't have shut off valves, you may need to turn off the water for the whole house. This will protect against damage to the faucet's shiny finish. One layer of tape will do. Any kitchen faucet with separate handles for hot and cold is a compression faucet. Remove a handle by popping off the decorative ("H" or "C") cap and loosening the screw beneath. Repeat the process on the other handle if it's also leaking. Use a tape-wrapped wrench and turn counterclockwise. Pull out the stem. Install a new O-ring for leaky handles, or a seat washer for a leaky spout. Both are rubber, but the O-ring is thinner. Take them to the hardware store if you need to find a match. It's the exact reverse process so if you managed to pull out the faucet handle successfully, you can put it back in too! Turn the water lines back on, then try the faucet and check for leaks. Unless you already know what kind of faucet you have either a "ball," "cartridge," or "ceramic disk" you'll need to look at the inner workings to figure it out. Unscrew and remove the handle itself: it may be on the lower front or rear of the handle or under a decorative cap which you can pop off to expose the allen screw. A ball faucet has a free-moving ball (usually rubber) that seats in a metal socket, similar to your shoulder or hip joint. A cartridge faucet has a cylindrical mechanism (the "cartridge") that will pull out in one piece. A ceramic disk faucet contains a shorter cylinder with several neoprene sealing rings on its underside. Your repair procedure will vary depending on whether you have a ball, cartridge, or ceramic disc faucet. In any case, the repair will involve several detailed steps, but the overall tools and techniques are not beyond the capability of most homeowners. Use the product instructions for your faucet, or print out a high-quality online guide with detailed images and instructions on repairing a ball, cartridge, and/or ceramic disk faucet. That said, there's no shame in calling a plumber if you're not sure what you're dealing with!

summary: Plug up the drain with a stopper or rag. Turn off the water to the faucet. Wrap the teeth of wrenches and pliers with duct tape. Remove one or both leaky handles on a compression faucet. Loosen the nut that holds the stem in place. Replace one or both rubber washers in the assembly. Reassemble the faucet handle. Remove the handle of a single-handle faucet to investigate. Get detailed instructions for your specific faucet type.

If you have a DSLR, you can probably adjust the ISO on an LCD screen on top and on the back of the camera. If you're shooting with a compact digital camera, you can use the LCD screen on the back. Depending on your camera, you may have a designated ISO control button located on the side or top of the camera. Check your manual to locate the control. If you're unsure where to begin or just want to pay attention to the optimal ISO for your photographs, use your camera's automatic ISO setting. If you have this selected, you won't need to manually adjust the ISO for your images. If you'd like some control, check to see if your camera will allow you to set limits on the ISO. For example, you might limit the ISO to 1600. Once you've pressed the ISO button on the back or top of your camera, you should either see a menu pop up on the LCD screen or see a single number appear on your small LCD screen. Use the scrolling wheel or arrow buttons to scroll through the numbers until you reach the ISO setting you want. Then select the number. If you want to control ISO and aperture or shutter speed, put your camera in AV (for aperture) or TV (for shutter) priority. These will also let you choose the ISO you'll be shooting at. For even more control, push your camera's Manual or Program button. These will allow you to select the ISO, aperture, and shutter speed.

summary: Locate your camera's ISO control. Choose your camera's auto ISO setting to start. Scroll through the ISO menu to choose an ISO setting. Play around with the semi-automatic settings.

There are many different kinds of day planner, suited to different tasks and personalities. Some day planners are very simple lined notebooks; other day planners have different sections for different kinds of tasks. Take a few moments to think about why it is you want to use a day planner and what you would use it for. It is very important to consider these questions because you will be more likely to use your day planner if it becomes your sole planning tool: keeping more than one day planner at a time will be confusing and will defeat the purpose. Ask yourself: Will I need a section for phone numbers? Will I use it primarily for remembering appointments? Do I want a day planner that lasts for more than one year? Do I want my day planner to replace another organizing tool (such as my to-do lists)? Do I want a simple, plain notebook, or one with lots of different features and sections? Would I rather have a day planner that is small enough to fit in a pocket or one that is large enough to handle notes from my meetings? Do I want a day planner that provides more space for weekdays, or will I need my day planner primarily for weekend activities? Day planners can be purchased at a variety of stores, such as office supply shops, stationery stores, calendar stores, and online. They can cost anywhere from just a few dollars to over $50. While the aesthetics of your day planner are important, pay attention first and foremost to the layout and sections of the day planner. Make sure that the day planner you purchase is organized in a way that you find pleasing and that makes sense given your lifestyle and responsibilities. Even though function is the most important thing, you will be more likely to get in the habit of using a day planner that you find attractive and pleasing to the eye. Some day planners are very simple, with just a plain black leather cover. Others are bright and whimsical, with lots of designs and elaborate patterns. Any aesthetic is fine as long as it accords with professional decorum in your workplace. Pay attention to the aesthetics of the inside of the planner as well as the outside. Some people prefer unlined pages to lined pages, for example. Some people like symmetry; others might like more dynamic layouts. You might also prefer certain typefaces to others. Make sure that you find your day planner pleasant to look at--inside and out--in order to further incentivize your daily use of it. Your day planner won't do you much good if you can't write anything down in it. Be sure to keep lots of sharpened pencils and working pens in places you are most likely to use your day planner. These include: Your briefcase or work bag Your purse Your work desk Your desk at home Close to your landline phones If you are someone who consistently loses pens and pencils, consider storing an emergency pencil inside your day planner itself. Some day planners even have a little bit of storage space you could use for a spare pencil.
summary: Consider what you would use a day planner for. Purchase a planner that suits your needs. Consider the aesthetics of your day planner. Have a ready supply of pens and pencils.
