Q: Start by using a scratch-free microfiber cloth for a general rub-down and preliminary cleaning. Wipe down the exterior of the case, and get rid of any easy-to-remove lint, dirt, and wax. You may use a little distilled water to help you along in your task; for more difficult grime, dampen the cloth using a small amount of isopropyl alcohol. But only use a very small amount of liquid. Dry is best, if possible. Your AirPods and their storage case are not resistant to liquids, so be careful to not get any fluid in the charging ports, or on the AirPods themselves. A swab gives you pinpoint accuracy, and lets you muscle through the gunk. If necessary, dampen the swab with distilled water to loosen dirt and wax. If you have really difficult-to-remove, caked-on dirt to contend with, moistening the end of a swab with a small amount of isopropyl alcohol should do the trick.
A: Give the case general cleaning. Dampen the cloth with a little liquid if necessary. Use cotton swabs to rub free any dirt or stains on the outside of the case.

Q: Whenever you notice a headache coming on, make note of it in your diary. Include the date and time the headache started. By including this, you'll be better able to spot patterns when you review the data you've gathered. Get into the habit of recording your headache right away, because if you wait you might forget important details. If you can't find the book, write the info on a piece of paper that you can transcribe to your book as soon as you can. In addition to the date and time of your headache, write down any associated symptoms. By writing down symptoms, you'll record information that could be useful to you or your doctor when it comes time to review your diary. Some symptoms you might experience (and record) include: Neck stiffness. Irritability. Light sensitivity Nausea Strange phenomenon (e.g., spots in your vision) Your emotional state (e.g., happy, sad, stressed, excited, etc.) In addition to writing down the start time of your headache, you should also record when your headache ends. At the same time, record any information about what helped you alleviate your discomfort (like medicine or darkness during the headache. Be specific about medications you took and how long they took to work. Note the type of medication and the dosage.
A: Write the time and date of your headache. Record the symptoms and severity of the headache. Note when the headache ends and what helped alleviate it.

Q: Make sure you have a sealable container to catch the old differential fluid as you drain it from the vehicle. Place the container beneath the drain bolt so the fluid will pour into the container once you remove it. Used differential fluid will need to be brought to a certified recycling location. Do not mix old differential fluid with oil or gasoline. Use a hand or socket wrench of the appropriate size to turn the drain bolt counter-clockwise to loosen it. Once the bolt is hand loose, use your hand to unscrew it while applying pressure inward to keep it from leaking as you loosen the plug. Once it is completely unthreaded, pull the plug away and let the fluid pour out. You may want to wear gloves to avoid getting old differential fluid on your hands. Make sure the vehicle is cool when doing this otherwise the fluid may burn you. It may take a few minutes for the differential fluid to drain out completely. Make sure the container is positioned properly and does not overflow as the fluid drains out. Allow the differential to drain until there is only a slow drip of fluid remaining. Seal the container once the differential has finished draining for storage and transport to a recycling center. Once the differential is empty, use your hand to thread the drain bolt back into place, then use the wrench to tighten it until the differential is once again sealed. Do not overtighten the drain bolt. It only needs to be tight enough to provide a seal. Be sure to use the correct size wrench to avoid stripping or damaging the head of the bolt.
A: Place a container beneath the differential. Remove the drain bolt. Allow the fluid to drain completely. Replace the drain bolt and wipe down the area.

Q: For the best results, bypass the analog connection entirely and connect your guitar digitally to your computer. You can connect your guitar digitally to your computer through a pre-amp with a USB or Firewire outport. Before you purchase a pre-amp with one of these out ports, check to see if the guitar accessories you already own will work. These accessories may include amp-modelers, pedals, drum machines, and direct boxes. Place your standard guitar cable into your guitar. Plug the opposite end of the guitar cable into the pre-amp's input port. Insert a USB, Firewire, or Optical cable into your pre-amp's USB or Firewire out port. Plug the other end of this cable into your laptop's USB or Firewire in port. When your guitar is properly connected, you will be able to assess the strength and quality of your guitar's signal. Listen to the instrument through your computer's speakers, a set of external speakers, or a pair of headphones. If you're using external speakers or headphones, insert their respective cables into your laptop's audio-out port. Play a few chords on your guitar to test the signal. This method will produce the crispest and clearest recordings. You may need to download and/or open recording software in order to hear your instrument. If your guitar's sound is not coming through, make sure the instrument's volume is turned all the way up. Open your computer's sound settings and double check that your volume is not muted and that the correct port or device is selected (audio-in, audio-out, headphone, microphone, etc.). For specific instructions, consult your computer or device's manual.
A:
Purchase or find a pre-amp device with a USB or Firewire out port. Connect your guitar and pre-amp to your laptop. Test the signal.
