chassis, or any other installed Bose

®

products.

CAUTION: Do not mount the ch as s i s to an uninsula ted
exterior wall or in locations where condensation may occur.

WARNING: To reduce the risk of fire or electric shock, do
not expose this system to rain or moisture.

CAUTION

RISK OF ELECTRICAL SHOCK — DO NOT OPEN

TO PREVENT ELECTRICAL SHOCK, DO NOT REMOVE

COVER. NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED PERSONNEL.

TO PREVENT FIRE OR SHOCK HAZARD, DO NOT

EXPOSE THIS UNIT TO RAIN OR MOISTURE.

CAUTION: Check local regulation s before instal ling or wirin g
the TA-2 theater amplifier. The building code may require
professional installation by a skilled technician or licensed
contr actor. Regional or electrical co d es may require s i mi lar
qualifications for wiring the system.

WARNING: The TA-2 theater amplifier is an electrical appli­ance. T here are no u s er-serviceable par ts insid e . A s with all
electr i cal appli an ces, dan gero us el ect ric al s hock may re sul t if
unqualified person ne l attempt repair. Only Bose-authorize d
personnel should perform service.

ADVERTISSEMENT : N’exposez pas ce système à la pluie
òu à l’humitit é a fin de réduire le r isqu e d ’in ce ndi e ou de choc

AVIS

RISQUE DE CHOC ÉLECTRIQUE—NE PAS OUVRIR

AFIN DE PRÉVENIR TOUT RISQUE DE CHOC ÉLECTRIQUE,

NE PAS ENLEVER LE COUVERCLE ARRIÈRE. IL NE SE

TROUVE À L’INTÉRIEUR AUCUNE PIÈCE POUVANT

ÊTRE RÉPARÉE PAR L’UTILISATEUR. S’ADRESSER

À UN RÉPARATEUR COMPÉTENT.

AFIN DE PRÉVENIR TOUT RISQUE D’INCENDIE OU DE

CHOC ÉLECTRIQUE, NE PAS LAISSER CETTE UNITÉ À LA

PLUIE OU À L’HUMIDITÉ.

CAUTION: To reduce the risk of electric shock, do not disas­semble the TA-2 theater ampl ifier chas s is. There are no user­serviceable parts inside. Refer servicing to qualified service
personnel.

The CAUTION marks shown here are on the bottom end of
the chassi s .

The li g ht ning flash with arrowhead symbol, within an
equila te ral tria ngl e, al er ts the user to th e pr ese nce of

uninsulated “dangerous voltage” within the chassis
enclosure. This voltage may be sufficient to constitute a risk
of electrical shock.

The exclamation point within an equilate ral tria ngle

alert s the u s e r to the prese nce of impo rtant op erat-

ing instructions in this installer’s guide.

WARNING: To prevent electric shock do not use this plug
with an extensio n cord, re ceptacle or other ou tl et unless the
blad es ca n b e f ul ly insert ed to p r event blade expos ur e .

AVIS DE PRECAUTION : Pour réduir e le risque de choc,
ne retir ez pas l e co uvercle de ce sys tème. Il n’y a pas de
pièces pouvant être réparées par l’utilisateur à l’intérieur.
Veu illez vous adresser a des ré p ar ateurs agréés en cas de
problème.

Le avis de précaution contenus sur cette page figurent à
l’arrièr e de votre s y s tè me.

Le symbol e d ’éclair avec une tête de fl èche con­tenue dans un triangle équilateral a pour but d’avertir

l’utilisateur de la présence d’une “tension dan­gereuse” non isolee à l’intérieur de l’ébén i s teries du s ystème
qui peut être asse z haute pour causer un risq ue d e cho c
électricque.

Le point d’exclamation contenu dans un triangle
équilateral, tel qu’il apparaît sur le système, a pour

but d’avertir l’utilisateur de la présence d’instruc­tions importantes relatives à l’utilisation et à l’entretien dans
ce mode d’emploi.

ATTENTION : Pour prevenir les chocs electriques ne pas
utilizer cette fiche polarizee avec un pro l o ng ateur, une prise
de couran t o u un e autre sort i e d e co urant, sauf s i l es l ames
peuvent etre inserees a fond sans en laisser aucune partie a
decouvrir.

Important Safety Instructions

19. Avoi d po we r l ine s – Use extreme care when installing
an outside antenna system to ke ep from touching
powe r l ines or circu its, a s c o ntact with the m may be
fatal. Do not install external antennas near overhead
power lines or other ele ctric ligh t or power cir cuit s, nor
where an antenna can fall into such circ uits or p o wer
lines.

20. Ground all outdoor antennas – If an external antenna
or cable system is connected to this produ ct, be sure
the antenna or cable system is grounded. This will pro
vide some protection against voltage surges and built­up static charges.

Section 810 of th e N ation a l Electrical Code ANS I /
NFPA No. 70 provides information with respect to
proper grounding of the mast and supporting struc
ture, grounding of the lead-in wire to an antenna dis­charge unit, size of grounding conductors, location of
antenna-discharge unit, connection to grounding elec
trodes, and requirements for the ground electrode.
Refer to the antenna grounding illustration on this
page.

Note to CATV system installer

This reminder is p rovide d to cal l the C ATV system
installer’ s attention to Article 820-40 of the NEC (of USA)
that provides guidelines for proper grounding. In particular,
it specifies that the cable ground shall be connected to the
grounding system of the building, as close to the point of
cable entry as is practica l.
