User manual BOSE FREESPACE 51 ENVIRONMENTAL SPEAKERS

[. . . ] The speakers are also designed for permanent outdoor installation, and therefore can withstand nature's elements ­ so you can be confident they will perform for years to come (see "Environmental capabilities", page 9). English Unpacking the carton Carefully unpack your Free Space 51 speakers and save all packing materials for possible future use. Check that your system contains all parts identified in Figure 1.

See "Cord recommendations" under "Technical Information" on page 9 for proper gauge, or check with your authorized Bose® dealer. · If your installation requires the cord to be buried in the ground, use direct-burial rated cable or run the cord through a PVC piping channel. Always use moisture-resistant speaker cord. · Place speakers and run cord before digging holes or burying cord. · If you think your speaker cord may be exposed to salt water or water containing chemicals such as chlorine or fertilizers, you may use a silicone caulking material as added protection for the speaker connections. 5 Setting Up Making the connections English WARNING: Before making any connections, turn off your receiver or amplifier and unplug it from the AC power (mains) outlet.
