Transmitter setup is the same to identify cables or pairs. However, Receiver
setups are different.
Perform a battery test; then with the transmitter off, connect the Dyna-
Coupler to the Transmitter front panel jack using the coupler cable.

Note:  Cable Identification requires two Dyna-Couplers: one at the
Transmitter and one at the  Receiver.

Clamp the Dyna-Coupler around the cable or both and tip and ring of a pair
and make sure the jaws fully close.

Press          to turn the Transmitter on and then twice more to select the
Tone mode 

.

Press 

 to change the high output level.

Press 

 to turn the Receiver on.

Press          to select Tone mode 

 .

Connect a second Dyna-Coupler to the Receiver accessory jack using the
earth frame cable or another coupler cable.

Press 

 to select the highest toning frequency (200 kHz).  Check the

first cable in the group by clamping the Dyna-Coupler around the cable.
Press 

 and observe the numeric display, which is relative signal

strength.  Remember the number and continue by clamping the Dyna-
Coupler around the next cable in the group. If the signal strength is greater
than the previous observation, press 

. If the signal strength is less than

before, ignore it. After checking all the cables in the group, the cable with
the highest reading is the one being identified.
