IMPORTANT SAFETY INFORMATION
WHAT's IN THE BOX

1) Insert the RJ45 plugs at the ends of the cable into the corresponding sockets on the
emitter and the receiver
2) Set the function switch of the emitter to “TEST”, the testing indicator will flash “VERIFY”,
this shows the emitter is functioning normally
3) Following the 8 wire sequences, the presence of short-circuit, broken wires, open
circuits or crossed wires can be ascertained.
4) During testing the SELECT button can be pressed to switch between fast and slow levels.
Open circuit of short circuit testing function
Set the function switch on the emitter to “TEST” and hold the SELECT button on the emitter for 2
seconds. The “VERIFY” indicator will change from flashing to lit. Insert the plug with crocodile clips
into the RJ45 socket, and clamp the two ends to be tested. If a short circuit is detected the LED “1”
of the sequence indicator of the emitter will light up, otherwise it will remain unlit. The line
resistance is indicated by the brightness of the status indicator, the brighter the LED the lower the
resistance.
OPERATION
Telephone wire finding function
1) Insert the telephone wire with an RJ11 plug into the RJ45 socket of the emitter.
2) Set function switch the emitter to “SCAN”, the wire finding indicator will flash “STATUS”.
3) Press and hold the test button of the receiver, using the probe on the receiver to locate
target wire at the other end.
4) During testing the select button can be pressed to switch between single and dual-tones.

Network wire finding function
1) Insert the RJ45 plug of the network cable into the RJ45 socket of the emitter.
2) Set the function switch of the emitter to “SCAN”. The status indicator will flash “STATUS”
3) Press and hold the test button of the receiver, use the probe on the receiver to locate the
target wire.
4) During testing the select button can be pressed to switch between single and dual-tones.
DC level testing function
Set function switch on the emitter to “SCAN” and hold the select button on the emitter for 2
seconds, the “STATUS” indicator will turn off and the “VERIFY” indicator will flash.
Insert the hard wired plug into the RJ11 (WH806B), and clamp the two ends to be tested. If the
“STATUS” indicator lights up in red, this means the end with the red clip is the positive pole. If the
indicator is green the end with the black clamp is the positive pole. The level can be judged by the
brightness of the indicator. The brighter the indicator, the lower the resistance is.
Low battery alarm
To check the battery level set the function switch on the emitter to “TEST”, if the battery level is low
then “STATUS” and “VERIFY” will both light up at the same time. This indicates that the battery
should be replaced.
Earphone usage
The receiver features an audio jack for headphones to allow discrete operation or ease of operation
in noisy areas.
Spotlight function
The spot light function allows the device to be used in darker areas or where lighting is limited.
