Loop Voltage Detector
The status indicators of your 2740 telephone are designed to light when a fax machine, modem, or
standard telephone is using a line. If the line status indicators of your 2740 telephones light when no
telephone is using the line or do not light when a standard telephone is using the line, the loop voltage
detector setting may need to be adjusted. The factory setting of 48 volts is appropriate for most
installations. This value can be changed to either 24 volts or 12 volts or the feature can be turned off.

Ringer Configuration
The ringers for each outside line are controlled individually at each telephone. There are three possible
settings for each line ringer:
RINGER ON: The line will ring normally.
DELAYED RING: The line will start ringing after the first 20 seconds. This is useful if all phones are
answered at a central location.
RINGER OFF: The line will not ring. In all these cases, the line indicators will flash to signal an
incoming call.
