I have an alpine mar 500 and 2 ten inch subs that i run, the subs are fine the amp has blinking light on it can't figure out why. the amp also has a blinking blue light on it could there be a solution


What gauge wire are you running from the battery to run your Alpine amp? If the amp isn't able to draw enough current to drive your subs, it will not function properly. It could possibly damage your gear. Also check that your battery and alternator are up to the task. Car audio will load up the charging system in a vehicle if it's low powered. You may need to upgrade your alternator and battery.

Kdc 448u has power but will not work


If you are sure that the unit has power, try resetting the unit. The reset button is on the left of the plug behind the faceplate.

Face plate keeps opening and closing since battery went dead and was replaced


If there is a reset switch, try pressing it. The reset switch is usually a pencil tip sized indentation on the face and will not be marked or will be behind the face on the sub panel.

When I load papers into the document feeder on top of my HP Officejet 7210 All-in-One printer to scan these documents, the PDF file (scan results) have a multi-color series of lines from top-to-bottom on...


  1. Remove all originals from the document feeder tray.
    NOTE: It might be easier to work with the automatic document feeder if the document feeder tray is removed first.
  2. Lift the cover of the automatic document feeder. Figure 1: Lifting the ADF coverc00222493.gif
  3. Lift the lid on the HP all-in-one, and locate the notch near the top right edge of the lid backing. Figure 2: Locating the notch near the lid backingc00222494.gif 1 - Notch 2 - Lid backing
  4. Place one or two fingers in the notch, as you lower the lid of the HP all-in-one. Keep your fingers in the notch until the lid is almost closed. Figure 3: Inserting fingers into the notchc00222495.gif
  5. Push against the top of the face plate with your thumb as you pull the bottom away from the right side of the HP all-in-one with your fingers. Use a slight twisting motion to help release the face plate on the right side.
    CAUTION: Do not pull the face plate all the way off yet. There is a plastic catch on the far left inside of the face plate that helps secure the face plate in place. If the face plate is pulled straight off, the plastic catch on the inside of the face plate might be damaged. Figure 4: Releasing the face plate from the right side of the HP all-in-onec00222496.gif 1 - Releasing the right side with a slight twisting motion
  6. Slide the face plate to the left until the plastic catch on the left side is not touching any part of the HP all-in-one, then pull the face plate away from the device. Figure 5: Removing the face plate from the HP all-in-onec00222497.gif 1 - Sliding the face plate to the left 2 - Pulling the face plate away from the HP all-in-one
Cleaning the rollers or separator pad Follow the steps below to clean the rollers or separator pad.
  1. Once the face plate of the ADF is removed, use the blue-green handle to lift the pick assembly. Figure 6: Blue/green handle and the pick assemblyc00222498.gif 1 - Blue-green handle 2 - Pick assembly This allows access to the rollers and the separator pad. Figure 7: The rollers and the separator padc00222499.gif 1 - Rollers 2 - Separator pad
  2. Lightly dampen a clean, lint-free cloth with distilled water, then squeeze any excess liquid from the cloth.
  3. Use the damp cloth to wipe any residue off of the rollers or the separator pad.
  4. If the residue does not come off using distilled water, try using isopropyl (rubbing) alcohol.
  5. Use the blue-green handle to lower the pick assembly.
Reattaching the face plate of the ADF Follow the steps below to reattach the face plate to the front of the automatic document feeder.
  1. Hook the face plate onto the left side of the HP all-in-one so that the plastic catch on the far left inside of the face plate catches on the notch on the front of the automatic document feeder. Figure 8: Hooking the face plate into the left side of the HP all-in-onec00222500.gif 1 - Notch 2 - Plastic catch
  2. Line up the right edge of the face plate with the right side of the HP all-in-one, and then press on the right side of the face plate until it snaps securely into place. Figure 9: Snapping the face plate into the right side of the HP all-in-onec00222501.gif
  3. Place your hands towards the center of the face plate, and press until the center of the face plate snaps into place. You should hear two clicks; one when the left side snaps into place, and one when the right side snaps into place. Figure 10: Finishing re-attaching the face platec00222502.gif
  4. Close the cover of the automatic document feeder.
  5. If you removed the document feeder tray, reattach it.

What does a green blinking light mean on my eco box? Also when cleaning the unit, which way does the metal plate face? Does the metal plate face towards the outside or the center of the unit. I'm...


When the green LED starts to blink, means that there is a bulb failure in the RCI module. It typically glows greenish blue when it working. Check the connector to see if it is seated properly, and also check the power connector for problems. I had a problem with the power connect not making a good contact and it caused the power to be intermittent. I was able to clean the connector with a can of electrical contact cleaner from Radio Shack to fix this problem. If you can't get the bulb to light, you will need a new RCI module.

As for the purification plate, the one that shaped like a tongue depressor, it does not matter which way it go back in to the unit. You should be able to get parts from your dealer or you can call the company at 800 989 2299. Hope this helps.

Annoying blue light on volume control.. can it be turned off?


The face plate is easy to take apart, just remove the face plate off the head unit and take the hex screws out and put a piece of tape over the bulb on the system board. Then put it back together again.

The car security is not connected to a head unit. It probably has a small blinking red light on it which blinks when you remove the faceplate and switch the ignition off. This is just an indicator which lets people see that the face plate is removed.

You can replace the headunit with any brand/model you want. It would be cheaper than buying a replacement faceplate.
