2.4.Loop Voltage Detector

Your 2750 telephone will light up its line status indicators when a telephone such as a fax machine, modem, or standard telephone is using a line. If the line status indicators of your 2750 telephone do not function properly, either failing to light up when a standard telephone uses a line, or staying lit even though no telephone is using a line, the loop voltage detector setting needs to be adjusted. The factory setting of 48 volts is appropriate for most installations. If this is not suitable, try setting your phone to 24 volts. If that does not work, then set it to 12 volts. You can also turn this feature OFF.
