Test adapter for voltage
1. Plug adapter into a working outlet.
2. Turn on meter to test for DC voltage.
3. Put one lead into the end of the plug and the other lead to the metal on the outside.
4 The adapter will be labeled 9VDC or 12VDC. When testing, the reading should be a few volts higher than the label says. If there is less voltage than what the label says, you need to replace the adapter.
Test harness for power supply voltage
1. After you have tested the adapter for voltage, plug in the machine and take the console off of the unit.
2. Turn on the meter to test for DC voltage.
3. Put one lead on the 1st wire and the other lead on the 3rd wire.
4 You should have basically the same voltage here as you had when you tested the adapter. If the reading is vastly different, the harness needs to be replaced.
Test gear motor
1. If unit is an XE550, go to motor test in engineering mode.
2. Take off right shroud so you can access the gear motor.
3. Turn meter on setting to check for DC voltage.
4. Check for voltage between the yellow and the red wires. (Should be around 4.5v for 350/550)
5. Check for voltage between the yellow and orange. Check for voltage between the red and orange. These two voltages should added together should total the voltage that you had between the yellow and red.
6. Press the START button and press the UP button. Check for voltage between the black and the brown wires. You should get 4-6 volts. (As you can see, you will need someone to help you with this step.)
Alignment of speed sensor and magnet
1. Using a flat screw driver or a knife, take off the round disc cover on the left side of the unit.
2. Turn the pedal so the bigger opening is at the top of the hole.
3. Sensor should be pointing directly at the large pulley and there should be a magnet in the on the pulley.
Adjusting brake cable
1. Take right and left shrouds off.
2. On the left side of the unit you will find the brake inside of the flywheel.
3. Using an open end wrench, loosen the small lock nut.
4. Using the same wrench, loosen the longer nut. As you loosen the nut you will see this gap get smaller.
5. The smaller the gap is, the easier the resistance will be at level 1. Dont adjust out the gap completely.
6. Tighten down the lock nut.
XE400 and XE500 Incline Calibration
If the console shows an incline error or does not seem to physically be at the incline displayed, the unit needs to be calibrated. Press and hold the START and level UP keys for 5 seconds. The message window will show “Calibration”; press ENTER. The calibration process is automatic and the system will restart when finished.
Troubleshooting
Thumping noise
1. Clean and lube wheels and rails.
2. If there is still a thump, check for loose bolts.
3. If there is still a thump, order new pedal arm bushing housings with IGOS plastic bushing.
Squeaking noise in the pedal(XE100 &XE200)
1. Order and install a new connecting arms.
Adjustable pedal not staying in the desired position (XE300)
1. Order and install new threaded bushing and crank pin.
Slide wheels jumping off of the track
1. Clean wheels and tracks with rubbing alcohol. All of the sticky and/or dirty lube must be removed from both the wheels and the tracks.
2. If the aluminum track has been damaged, order a new aluminum track.

Nokia N900

Turn the phone over so the screen is face down.
Remove the back cover by locating the slit on the bottom of the phone and lifting up.
Remove the battery by lifting it out of the device.
Remove the two "L-shaped" antennas by unscrewing the following screws:
Four screw M1 .4x5.0
Two screw RF1 .4x4
In addition to unscrewing the screws, remove the B-Cover (which will fall right out without the screws).
You will now have two halves of the phone.
Grab the half of the phone that has the keyboard on it
Remove the keyboard by unsnapping the frame and then lifting the pad out from the device.
Place the key pad and cover to the side for the remaining steps.
Use a blue plastic opening tool lift the motherboard out of the back cover
Look at the bottom of the motherboard to find the USB Port

Samsung Galaxy S4

MOTHER BOARD REPLACEMENT PROCEDURE 
Pry with a plastic opening tool, or your fingernail, in the divot to the left of the rear-facing camera, near the power button.
Lift the rear case by the corner nearest the divot and remove it from the phone.
Use the flat end of a spudger, or your fingernail, to press the microSD card slightly deeper into its slot until you hear a click.
After the click, release the card and it will pop out of its slot.
Remove the microSD card.
For reassembly, push the microSD card into the slot until it clicks in place.
Insert a plastic opening tool, or your finger, into the notch of the battery compartment and lift the battery upward.
Remove the battery from your phone.
Use a plastic opening tool, or your fingernail, to press the SIM card slightly deeper into its slot until you hear a click.
After the click, release the card and it will pop out of its slot.
Remove the SIM card.
During reassembly, push the SIM card into the slot until it clicks in place.
Remove the nine 4.0 mm Phillips #00 screws securing the midframe to the display assembly.
The midframe is secured to the display assembly by several plastic clips behind the chrome bezel of the midframe. The next few steps will guide you through separating the clips to free the midframe.
Starting on the volume button side of the phone, insert your plastic opening tool between the chrome bezel around the display glass and the larger chrome border piece. Look for the seam between the two.
Slide the opening tool along the seam, separating the plastic clips as you go.
Be very gentle whilst prying, and pry only enough to separate the plastic clips—there are several thin points in the midframe bezel that may crack if you bend them too much.
Continue prying around the corner of the phone.
Slide your opening tool along the seam between the midframe and display along the bottom of the device, releasing more of the plastic clips.
Again, pry around the corner, to the power button side.
Slide the opening tool along the seam.
Continue sliding the opening tool around the top of the phone, releasing the last of the clips and freeing the midframe from the display assembly.
At this point, you may want to run your plastic opening tool along the entire perimeter of the device again, to make sure you've released all of the plastic clips.
Remove the midframe from the display assembly.
Use the flat end of a spudger to disconnect the USB board connector.
Disconnect the front-facing camera cable connector.
Disconnect the earpiece speaker assembly cable connector.
Disconnect the headphone jack assembly cable connector.
Disconnect the display/digitizer cable connector.
Disconnect the antenna cable connector.
Remove the single 2.4 mm Phillips #00 screw from the motherboard assembly.
Gently remove the motherboard.
Hold the motherboard by its edges to prevent ESD damage. Be careful not to snag it on any cables as you extract it from the display assembly.
Use the flat end of a spudger to disconnect the rear-facing camera connector.
Using tweezers, or your fingers, slide the rear-facing camera out of its notch in the motherboard.

FH
Causes
Detects No Water Entering Machine or No Pressure Switch Trip
Solution
Select 'cancel' twice to clear this code. If there is NO water in the unit, make sure the valves are turned on all the way. Check for plugged or kinked inlet hoses, as well as plugged screens in the inlet valves. Verify that the inlet valve is operational. If there is water in the unit, verify the drain pump is working and the pressure switch hose is in good condition and properly connected. Make sure there is not a siphon problem and check all hoses for possible leaks. Unplug the unit and disconnect the power to check all wire harness connections to the inlet valve, pressure switch, drain pump, flow meter, and Central Control Unit (CCU). Reconnect the unit and power to verify the pressure switch is operational, as well as the flow meter (blow air through the flow meter and measure resistance).
