EasyFinder (tone generator and line tester)
Maximum withstand voltage – not for test use:
CONT MODE (resistance test) TONE MODE (tracing tone) 120 V AC
Switch ON:
By pressing the ON/OFF button EasyFinder is turned on/off. The LEDs depend on the
position of the sliding switch.
Position:
TONE = ALT-LED flashes
CONT = CONT- LED LED flashes briefly
The EasyFinder automatically shuts off after 90 minutes. To disable auto shut-off, press
the ON/OFF button twice within one second after the device is turned on. In addition,
the SOLID LED flashes briefly. If you are in the SOLID tone mode, it is the ALT LED that
flashes briefly.
Switch OFF:
To Shut the Unit Off: Press the ON/OFF button for more than
1.5 seconds. The ALT and SOLID LEDs light briefly, and the unit turns off.
Line Status:
Quick display of the status of analog telephone lines, testing for voltage on digital
lines or alarm system wires, and much more. The status of analog telephone lines is
easily checked by turning on the EasyFinder and inserting it into wall jack. This is easily
done, using the RJ11 connector though it can also be done using the optional break-
out adapter or by simply clipping the device onto the wires using alligator clips.
Idle telephone lines have voltages up to 70 V DC, and the POL LED shines brightly
when the tester is connected. Red indicates a/b (T/R) inverted, green indicates correct
polarity, i.e., a-wire, ring or negative on the red terminal. EasyFinder indicates with the
red warning LED when the voltage on the line is greater than 90 V. This information
can also be used to identify the voltage at the ISDN U-interface (92 – 96 V DC).
Busy analoge telephone lines have voltages between 10 and 20 V DC, and the POL
LED is dim when the tester is connected. Red indicates a/b (T/R) inverted, green
indicates correct polarity. This is useful for determining if the line is busy or not in a
distribution box. The POL LED is orange when pure AC ringing voltage is present. With
the EasyFinder, any kind of voltage source can be checked for polarity, type of voltage
and its approximate level. The latest EasyFinder is high impedance in any mode, mean-
ing EasyFinder draws no line current to drive the POL LEDs.
