Use method of receiver
Remove the cover of battery pack, properly place in 9V battery, replace the
battery cover, hold the receiver and press and hold "Test" key with the thumb,
and then keep the detecting head close to the cable to find the target cable
among lots of cables. When the detecting head goes close to the target cable,
it beeps, and the same time the signal indicator "POWER" lights. Compare
loudness of beeps and brightness degree of the signal indicator. The cable
with loudest beeps and the highest brightness is just the target cable to find.
In a dark test environment, you may turn on lighting lamp on the receiver for
easy test as shown in the figure below:
