SECTION 5: TROUBLESHOOTING AND MAINTENANCE
5.1 Troubleshooting
WARNING!
DO NOT OPEN the case and attempt repairs without specific authorization by ELITechGroup Inc.
To do otherwise voids the Macroduct Advanced warranty and might also pose a significant risk.
It is strongly recommended that any malfunctioning device be returned to ELITechGroup for
service even after the warranty has expired. Repairs made by electronic technicians who are not
completely familiar with the fail-safe features of this device may render such features
inoperable.
Using Functional Test for Troubleshooting
The Functional Test combines the testing of the electrode cable assembly
with the cable detect circuitry, Pilogel detect circuitry, and iontophoresis
circuitry of the device.
To execute a Functional Test:
1. From the Home screen, tap . From the System screen, tap
Functional Test.
2. Connect the electrode cable to the device.
3. Place a single Pilogel disc between the two electrodes. Use an
electrode strap to hold them together.
4. Tap to begin the test.
5. A progress status bar displays the progress of the test. As specific
tests are completed, results display on the screen. If an error
occurs, the error code gets displayed, but the error does not stop
the test. The test continues until all three tests have been
completed.
6. The test can be stopped at any time by tapping .
The Functional Test performs the following:
• Verifies that the Macroduct Advanced electrode cable assembly is
connected to the device.
• Verifies that a Pilogel disc is in each electrode (two discs are not
required for this test).
• Iontophoresis ramps to full current (1.5 mA), verifying that the
current is within the specified tolerance. Full current is held for a
few seconds and then ramps down to zero mA. Duration of the
test is less than one minute.
7. Tap to return to the System screen, or tap to return to the
Home screen.
