. Refer to the owner's guide that came with it for instruction on settings. • If your 251™ speakers are connected as a second set of speakers to your receiver or amplifier, check that the connections have been made to the “B” terminals and that the “B” speakers are selected to play. The bass or treble is weak • Check the tonal balance setting on your receiver or amplifier. Only one speaker plays Only one speaker still plays • Check the balance control on your receiver or amplifier and make sure it's centered. • Check the wires connected to the speaker that does not play. Make sure the wires are in good condition and are firmly connected. Review the “Making the connections” section on page 9. • Disconnect the working speaker from the receiver or amplifier. • Switch the cord of the “faulty” speaker from its original receiver or amplifier jacks to the other set of jacks (the working speaker was originally attached to those jacks). - If the speaker now works, the problem is in your receiver or amplifier. Reconnect your speakers to a working unit. - If there is still no sound from the speaker, continue below. • Remove the cord from the working speaker and connect it to the “faulty” speaker. - If the speaker now works, the problem was in the original speaker cord. - If there is still no sound, the problem is in the speaker. • If trouble persists, contact your authorized Bose® dealer, who will arrange for service. Or, contact Bose customer service. See the inside back cover of this owner's guide for a list of phone numbers. Warranty period Bose 251 environmental speakers are covered by a limited five-year transferable warranty. Details of coverage are on the warranty card that came with your speakers.

See the inside back cover for offices and phone numbers. Cleaning your speakers Use a cloth dampened in mild detergent and water to remove dust or dirt from the outside of your 251 speakers. Or use a hose to rinse them thoroughly with fresh water. Do not use enough pressure to force water behind the grille and into the drivers or the acoustic ports. Protecting the speaker wire The bare ends of the speaker cord can be affected by exposure to the elements. This is especially true of saltwater exposure. You may use a silicone caulking material, such as RTV adhesive, to protect the connections. It is commonly available at hardware stores. If you do use caulking, apply it only after the wires are connected and the knobs tightened down. Check the connections annually, and reapply as needed. 12 Product Information Technical Information Protective features Galvanized powder coated steel grille Environmentally resistant hardware Polymer fiber composite drivers Nickel-plated brass connection terminals Syncom® computer quality control Driver complement Two (2) 214" environmental Twiddler™ drivers per speaker One (1) 5V^4" environmental woofer per speaker Enclosure Dual-port molded polypropylene composite Black or white Dimensions 1314" H x 534" W x 8" D (34.29 cm x 14.6 cm x 20.32 cm) Compatibility Compatible with amplifiers or receivers rated 10-200 watts per channel/rated 4 to 8 ohms 100W IEC continuous power handling; rated 6 ohms Environmental Capabilities • Designed to withstand: - salt fog, sun, high humidity (100%RH) - temperature extremes (-40°F to 158°F; -40°C to 70°C) Wire recommendations • Based on a maximum frequency response deviation of ±0.5 dB Gauge Length 18 (0.75 mm2) 30 ft (9 m) maximum 16 (1.5 mm2) 45 ft (14 m) maximum 14 (2.0 mm2) 70 ft (21 m) maximum Weight • 8 lb (3.63 kg) each 13 Better sound through research* ©2004 Bose Corporation The Mountain, Framingham, MA 01701-9168 USA 250811-ENGvo AM Rev.04 The Bose® 251™ Environmental Speakers Notice d'utilisation Informations personnelles Les numéros de série se trouvent sur l'étiquette collée au dos des enceintes d'extérieur 251™.
