No source conflict recorded for this model
The sources we consulted for this model agreed with each other. That is not a guarantee the manufacturer’s documents agree everywhere — only that we found no disagreement between the spec page, the manual and the listings we checked. Where we do find one, we publish both values and both sources instead of quietly choosing the more convenient figure.
