130 CHAPTER 3: TELEPHONES AND ATTENDANT CONSOLES 3Com Cordless Telephones Connection details for the 3106C and 3107C Cordless Telephones are included in the Cordless Telephone Guide. The guide also covers each of the accessories that are shipped with the telephone. See Table 29 and the installation notes that follow for installation guidelines. Table 29 Cordless Telephone Installation Guidelines Telephone Model 3106C (3C10406A) 3107C (3C10407A) Max range (ideal conditions) Approximately 915 meters (3,000 ft.) Approximately 1,370 meters (4,500 ft.) Cordless Telephone Installation Notes ■ Because of radio frequency issues, you can install a limited number of cordless telephones in one location. In an ideal environment, up to 10 cordless phones can be used in the same environment. For installations of three or fewer cordless telephones, 3Com recommends that you use 3107C Telephones. For installations of 3 to 10 cordless telephones, 3Com recommends that you use 3106C Telephones. ■ Table 29 shows the telephones' range (the distance between the base unit and the telephone) under ideal conditions. The actual range depends on environmental factors such as building structure, size of the room, RF interference, and other electronic equipment installed in the same area. A higher location for the base unit reduces the factors that can interfere with the coverage area. ■ Place the base unit in the center of your coverage area. If the phone will be also used in the outdoor area, install the base unit an area close to the window. ■ For best performance, make sure you have at least five meters of space between base units and that each base unit antenna is raised to the vertical position. ■ Avoid placing the base unit in a location surrounded by metal surfaces or near a PC, a monitor, or a telephone.
