manufacturer of the cable.
Ground terminal
• Depending on the circumstances of a particular setup,
you may experience a discomforting sensation, or
perceive that the surface feels gritty to the touch when
you touch this device, microphones connected to it,
or the metal portions of other objects, such as guitars.
This is due to an innitesimal electrical charge, which
is absolutely harmless. However, if you are concerned
about this, connect the ground terminal with an external
ground. When the unit is grounded, a slight hum may
occur, depending on the particulars of your installation.
If you are unsure of the connection method, contact the
nearest Roland Service Center, or an authorized Roland
distributor, as listed on the “Information” page.
Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in re or explosion)
• Telephone-line ground or lightning rod (may be
dangerous in the event of lightning)

Vorbereitungen
1. Führen Sie den Gurt durch die Halterung.
2. Befestigen Sie den Gurt am Gurt-Pin.
Bevor Sie das Gerät einsetzen, lesen Sie die folgenden Abschnitte sorgfältig durch: „SICHERER BETRIEB DES
GERÄTES“ und „WICHTIGE HINWEISE“ (S. 11; S. 14). Diese Abschnitte liefern wichtige Hinweise zum sicheren
Betrieb des Geräts. Um sicherzustellen, dass Sie mit dem gesamten Funktionsumfang Ihres neuen Gerätes
vertraut sind, sollten Sie die Bedienungsanleitung vollständig lesen. Bewahren Sie diese Anleitung an einem

Anbringen des Tragegurts
HINWEIS
• Verwenden Sie nur den mitgelieferten Gurt.
• Befestigen Sie den Gurt so, dass er sich nicht versehentlich
lösen kann. Falls der Gurt locker ist, während der MOBILE
AC am Gurt getragen wird, könnte der Verstärker zu Boden
fallen, was Schäden oder Verletzungen verursachen kann.
• Machen Sie keine Dreh- oder Schwingbewegungen mit
dem MOBILE AC, während Sie ihn am Gurt halten. Dies ist
äußerst gefährlich, da sich dadurch der Gurt lösen oder,
wenn die Bewegung zu oft wiederholt wird, sogar reißen
kann.
• Der mitgelieferte Gurt ist für den ausschließlichen
Gebrauch mit dem MOBILE AC vorgesehen. Verwenden Sie
diesen Gurt nicht für andere Produkte.
