Error messages deck a - Sony RCD-W1 2-Disc CD Recorder

Get the Code from Volvo, remove your battery cables for Half an Hour, replace cables. turn on stereo and enter the anti-theft code.

Just change main drive belt in new one.

Bring it to a Technician as this question gives very little information to work with.

You may have to dismantle the player unfortunately.

E6 or E7 An E6 or E7 error code is an incline error code. The E7 code means the potentiometer value the console is reading from the lift motor is out of range. This can happen when there is a bad wire harness connection or a damaged wire harness. It could also just mean the incline motor needs to be adjusted back into range. If all wire connections look ok, the incline motor will need to be adjusted.

1. Turn the power OFF, wait for 5-seconds and turn back ON.
2. Get into test mode and enter through the I/O testing step. This screen will display the potentiometer value of the incline motor. Different models will have different values. Check to see if the running deck is raised to high incline level or if it is at the low level. If the running deck is at a low position press the incline up button. This will cause the incline motor to raise the running deck up. When the deck gets to a mid-level position, press the incline up button a second time to stop the deck. If the running deck is in a high incline position, use the incline down button to adjust the deck to a mid-level position.
3. Once the unit is in the mid-level position, power the treadmill off for 5-seconds and then power it back ON.
4. Start the treadmill.
5. Once the treadmill starts the running deck will move to the level 0 position. If this does not resolve the issue or it will not adjust please contact customer service.

Also, note that not all models will have the ability to adjust the incline motor. If the adjustment procedure is not found in the Owner's Manual then contact customer service. Treadmill Error Codes Troubleshooting

The loading deck is out of sequence Check to see that the loader is in the correct position. reset & it should work properly

Their might be high friction between the belt and deck thus causing the error 1 code when your husband is on it. Try lubricating the area between belt and deck using silicone lubricant ( refer to owners manual). Then the lighter of the two "aka wife" walk on the treadmill for about 5 to 10 minutes.
This should take care of the problem if not then their is an issue with the belt and deck ( 85% of problems on treadmills are belt and deck related)

On Sony DSR-80P error 02-221 and 02-291 is a problem with the tape pull-in or eject. Mostly the tape stickers are bad situated over the stripe-cover at the top, which should be moving freely!
Remove the stickers from the tape or put them lower on the case. If the tape is already inside the machine is unable to reject the tape - disconnect the machine from electricity to open it or call service...

greetings from berlin, matt.

H02 error on AG-1980 is a "capstan motor error." most likely problem is a defective capstan motor.

check the drive belts in both decks. they stretch with age.
