note that the performance of any compass feature will vary depending on
environmental conditions. For example, any source using electromagnetic
or radio waves.
Before using any compass feature the compass needs to be calibrated for
accuracy. To calibrate, please disconnect the AC adaptor and remove all
peripherals/cables, and then horizontally rotate the computer with the
power on several times as shown in the illustration below. Please note this
is the most effective method of calibrating this computer.
