with the manufacturer’s instructions.
8. Do not install n ear any heat sour ces such as r adiators, heat
regis ters, stoves, or other a pparatus (inclu ding amplifiers)
that produce heat.
9. Do not defea t the safet y purpose o f the polariz ed or
grounding-typ e plug. A polari zed plug has t wo blades with
one wid er than the other. A grounding-t ype plug has t wo
blade s and a third grounding prong. The wide blad e or
the third prong is provided for your safet y. If the provid ed
plug does not fi t into your outl et, consult an electrician for
repla cement of t he obsolete outlet.
10. Protec t the power cord from being w alked on or pinched,
particularly at plugs, c onvenienc e recept acles, and t he point
where they exit from the apparatus.
11. Only use atta chments/acc essories specified by the ma nufacture r.
12. Use only with a c art, stand, tripod, bracket, or
table specified by the manufacturer, or sold with
the apparatus. When a c art is used, use caution
when moving the cart/app aratus combina tion to avoid injury
from tip-over.
13. Unplug this app aratus during ligh tning storms or whe n
unused for long periods of time.
14. Refer all servicing to qualified service personnel. Se rvicing
is required when th e apparat us has been d amaged in any
way, suc h as power-supply cord or plug is dam aged, liquid
has been spilled or object s have fallen into th e apparat us,

WATCH FOR THESE SYMBOLS:
XLi Se ries amplifi ers require Class 2 outpu t wiring.
CAUTION! Do not loc ate sensitive high-gain equipment such a s
preamplifiers or t ape decks directly above or below the unit. Becaus e this amplifie r has a high power density, it has a strong magnetic field which can induce hum into unshielded devices that are
loca ted near by. The field is s tronges t just above a nd below th e unit.
If an equipment rack is used, we recommend locating the
amplifier(s) in the bottom of the rack and the preamplifier or
other sensi tive equipment at t he top.
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
CAUTION: Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to
operate the equipment.
NOTE: This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
