Article: Select ripe, unblemished and unbruised fruit. Wash the fruit under cool running water, and gently scrub them with a vegetable brush if necessary. Fruits such as apples, pears and stone fruits should be peeled, sliced and cored or deseeded. Remove the stems and leaves from the fruits if necessary. Keep the jars and lids hot until they are ready to be filled. Jars and lids can be kept hot by placing them upside down in a pot of hot water or by washing them in a dishwasher and keeping them in the dishwasher until needed. Heat water to a boil and dissolve sugar in the following proportions: For a very light syrup with the fewest amount of calories add 3/4 cup (180 mL) of sugar to 6 1/2 cups (1.5 L). For a light syrup, ideal for very sweet fruits, add 1 1/2 cups (360 mL) of sugar to 5 3/4 cups (1.4 L) of water. For a medium syrup, ideal for sweet apples, cherries and berries, add 2 1/4 cups (532 mL) of sugar to 5 1/4 cups (1.2 L) of water. For a heavy syrup, good for tart fruits, add 3 1/4 cups (769 mL) of sugar to 5 cups (1.2 L) of water. Cover the fruit with the sugar syrup allowing 1 inch (2.5 cm) of air space at the top of the jars. Stir jars to allow air bubbles to escape. If you wish to use the hot pack method, instead of canning raw fruit, add fruit to the sugar syrup, return to a boil, cook the fruit for 2 to 3 minutes and fill the jars immediately. If canning low-acid fruits with a pH level higher than 4.6, such as Asian pears, add 1 tbs (14.8 mL) of bottled lemon juice. Place the sealed jars on the rack in the boiling-water canner filled halfway full of hot water. Add additional hot water until there is 2 inches (5 cm) of water above the tops of the jars. The jars must not sit directly on the bottom of the canner, and should not touch each other to allow steam to flow freely around them. Process jars in the boiling-water canner, for the recommended process time based on your altitude and the type of fruit you are canning. Start timing when the water has returned to a boil. Add additional boiling water if the water level lowers below 2 inches (5 cm) above the tops of the lids. Maintain a vigorous boil throughout the entire processing time (usually between 20 and 30 minutes.) Keep 1 to 2 inches (2.5 to 5 cm) of space between jars to allow air to circulate. Listen for a small "ping" sound indicating that the seal of the jar lids has been sucked down and the jars are properly sealed. This could take around 12 to 24 hours.
Question: What is a summary of what this article is about?
Prepare the fruit for canning. Clean 9 glass pint (500mL) canning jars and metal lids with soap and hot water. Prepare a simple sugar syrup. Fill the clean jars with the washed and prepared fruit. Wipe the rims of the jars with a clean cloth, shake gently to allow air bubbles to escape and cover with the metal lids. Place the cover securely on the canner and heat water to boiling. Remove the jars from the canner with a jar lifter and place them on a wooden board or thick kitchen towel to allow them to cool in a draft free area. Label the jars with ingredients and the date, then store in a cool, dark and dry location.

Problem: Article: The latch should be black, square, and located at the bottom end of the key holder. Your Mercedes key will fall out of its holder. Hold out your other hand to catch it as you pull the latch to avoid losing it. After you remove the key, you should notice an empty slot around the bottom end of the key holder. Turn your key holder sideways and push your key into the slot. Push the key entirely in, until you cannot push it further, to open the battery compartment. When your key has triggered the latch, the top of the battery compartment will jut out slightly. Grab it by the end and pull it slowly out of the key holder. Once pulled out, you should notice 2 exposed battery slots. Take out your 2 old batteries and replace them with 2 new ones in the designated slots. Slide the battery compartment back into the key holder until you hear a click. Put your key back into the slot vertically until it is secure as well.
Summary: Pull the latch at the end of the key holder down. Stick your key horizontally into the open slot. Lift the battery compartment up and out of the key holder bottom. Remove and replace your CR 2025 batteries.

Keep a fire extinguisher ready to go in areas where you work with electrical equipment. Fire extinguishers for use on electrical fires will have a "C," "BC," or "ABC" on the label. No matter how many precautions are in place, electric shock is always a risk when electricity is in use. If shock occurs, it is important to be prepared in order to handle the situation safely. In the case of an electric emergency, always call the Emergency Services. It is unwise to try to treat the victim yourself when an electrical shock has occurred. Shock victims usually don't hold the electricity in their bodies for very long. However, you must always use caution, as the victim could potentially still be conducting electricity. Use a non-conductive barrier, like rubber gloves, if at all possible, to touch or move the victim. If you can do so without being shocked yourself, turn off the power. If this is not possible, move the victim away from the source with a non-conductive material, like a piece of wood. You should only try to move an electrical shock victim if the person is in immediate danger. Once you are certain the victim is no longer conducting electricity, check to see if the person is breathing. If the victim is not breathing, begin CPR immediately while someone else alerts emergency medical services. OSHA's safety rules for working around electricity state that you have about 4 minutes to get help for an electric shock victim, so move quickly. Stay calm and keep the victim lying horizontally, with his legs slightly elevated until medical help can arrive. Once help arrives, stay out of the paramedics' way. If the paramedics ask for any assistance, follow their instructions.
