SECTION 5: TROUBLESHOOTING AND MAINTENANCE
5.1 Troubleshooting
Aside from electrode cleaning, there is no regular periodic maintenance required for the
Macroduct Advanced. If the system appears to malfunction, use the following information to
identify and remedy the problem. Contact ELITechGroup if the information below does not
resolve a problem.
Table 5: General Troubleshooting and Diagnosis (continued)
Symptom Probable Cause/Solution
Nothing happens when the
power switch is pressed.
(No indication that the device
is turning on and the green
LED does not light.)
Probable Cause:
Low battery.
Possible Solutions:
Charge the battery.
If the battery cannot be charged (amber LED not blinking during charge or
battery charge screen does not appear), contact ELITechGroup for further
instructions.
Iontophoresis will not start. Probable Causes:
Before iontophoresis can begin, the electrode cable must be plugged into the
device and Pilogel discs must be detected.
Possible Solutions:
Check that the Macroduct Advanced cable is securely connected.
Check both electrodes ensuring that a Pilogel disc is present and securely
positioned inside both electrode housings.
Ensure both electrodes are secured with adequate tightness to the patient’s
limb.
If the problem persists, with electrodes not attached to a patient, try
checking the electrodes from the System screen. (From the Home screen,
tap , , tap System, tap Functional Test.)
Iontophoresis begins
increasing current but does
not reach full current.
Probable Causes:
High skin or electrode-to-skin resistance.
Possible Solutions:
Inspect the electrodes and clean if necessary. Place a drop of deionized water
between the electrode and Pilogel disc and directly on the clean skin beneath
the Pilogel disc.
Ensure both electrodes are secured with adequate tightness to the patient’s
limb.
Suggest repeating the test once.
If the problem persists, with electrodes not attached to a patient, try
checking the electrodes from the System screen. (From the Home screen,
tap , tap System, tap Functional Test.)
