110 APPENDIX A: TELEPHONE INSTALLATION AND MAINTENANCE Selecting the Installation Location Select a location that avoids excessive heat or humidity. The base unit of the 3Com Cordless Telephone can be placed on a desk or tabletop near a standard 120V AC outlet and an RJ45 connection to the LAN. The base unit can also be mounted on a standard AT&T or GTE wall plate using the wall mount adapter. Keep the base unit and handset away from sources of electrical noise (motors, fluorescent lighting, computers). Following are some additional installation recommendations: ■ If you are using three or fewer 3Com Cordless Telephones at your site and require maximum operating range, use 3Com 3107C units. ■ If you are using more than three 3Com Cordless Telephones at your site, use 3Com 3106C units. ■ For optimum performance, place base units at least 15 feet apart. ■ Place base units in the center of their coverage areas. ■ Place base units close to windows, when coverage areas extend outdoors. ■ If you use more than one 3Com Cordless Telephone in your office, each unit must operate on a different channel. Press the CH button (3Com 3106C) or the Channel button (3Com 3107C) to select a channel that provides the clearest communication on each unit. ■ If you encounter interference or noise, press the CH button (3Com 3106C) or the Channel button (3Com 3107C), to try other channels.
