and/or palpating near the probe. It is suggested that the system be tested using the following two-step
approach.
Step 1 Monitor Only Test
The Channel/Cable Verifi er may be used to verify function of the fl ow monitor, and is to be used after testing
via the TEST MODE.
A. Align the red dot on the metal connector of the Channel/Cable Verifi er with the red dot on the
connection jack of the monitor, and insert until a click is heard. You should not be able to remove the
verifi er with a slight pull. Turn the monitor on and set the volume to the maximum setting.
B. Rub the exposed end of the verifi er with your fi nger and listen for a corresponding sound from the
speaker.
C. If an audible signal is heard as a result of rubbing the Channel/Cable Verifi er, you have confi rmed that
the fl ow monitor is receiving the signal correctly through the selected channel connector. Proceed to Step
2 Monitor and Extension Cable Test to test the Cook Doppler extension cable while it is connected to the
Cook Doppler Blood Flow Monitor.
If no sound is heard, replace the monitor and follow the instructions provided in the TEST MODE (TEST
BUTTON) section of this insert.
Step 2 Monitor and Extension Cable Test
A. In this step the Channel/Cable Verifi er may be used to assess the function of the Cook Doppler Blood
Flow Monitor while it is connected to the Cook Doppler extension cable. Be sure that the desired channel
button has been depressed and its corresponding LED illuminated.
B. Insert the thinner red connector located on the verifi er into the red JST connector located on the distal
end of the extension cable (black dots should be aligned). The two should fi t snugly, and not be easily
removed. Turn the monitor on, and adjust the volume to its maximum level. Rub the exposed end of the
verifi er with your fi nger and listen for corresponding sound from the speaker.
C. If an audible signal is heard from rubbing the end of the verifi er, you have confi rmed that the
monitoring system is functioning from the extension cable back to and including the monitor. Proceed to
D.
If no sound is heard after rubbing the Channel/Cable Verifi er but sound was heard in Step 1, replace the
extension cable and repeat Step 2.
D. If the probe still does not produce an audible signal, either the probe is: not functional as desired, has
been dislodged, fl ow has been disrupted from patient re-positioning, or fl ow restriction has occurred. The
responsible physician should be consulted immediately to determine the plan of action, unless he/she has
already established a protocol. (Repositioning the patient or palpating close to the probe site may be all
that is needed to re-establish the signal and continue monitoring.)
