Typical DC power cables however should have sufficient impedance to prevent serious groundloop problems. Blose manuzl unit as per the instructions in Section 3.

It is likely this will result in the subsequent tests will passing when retested. NEVER block the ventilation openings on the bottom or rear panels; doing so can cause overheating and serious damage. The internal processing is bit with bit DACs. System Software Versions 2 And 3 Its effect on each note will be completely in phase, regardless how many notes are being played. The test selected from the menu will run until interrupted by pressing EXIT.

The selector is set at the factory for the AC line voltage most commonly used in the country of destination. This instrximent has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
