IMPORTANT
The most common operational problems associated with electrotherapy
devices center around the lead wires and electrodes.
Please read the following information concerning these components.
Electrode and Lead Wire Test Mode
To test for defective lead wires and/or electrodes follow this procedure:
a. Hold down the STOP key for 5 seconds, until all 8s appear in the Frequency section, 10 appears
above Time and 01 appears in both channel 1 and channel 2 output.
b. Plug lead wire into either channel 1 or channel 2.
c. Hold the two lead wire pins together and observe the readout in the output LEDs above. If the readout is 9 or
10, the lead wire is good. (For further assurance, stress the wire back and forth at the pin and also at the end
where it enters the unit. The readout should stay at 9 or 10. A uctuation would indicate a broken wire making
intermittent contact.) If the readout is less than 9 or if it uctuates, replace the lead wire.
d. To test electrodes, insert one lead wire pin into an electrode. Touch the other pin to the conductive side of the
electrode and observe the output LED. If the output reads 9 or 10 the electrode is good. A reading of 8 or less
indicates a defective electrode which should be replaced.
e. For proper performance use non-expired LSI International Silver Tab Repositionable Electrodes. Reorder
numbers #LSI2204 (2” x 2”) and #LSI2404 (2” x 4”).
f. If using carbon rubber electrodes use only electrotherapy conductive gel. Do not use topical analgysics,
ultrasound medium/gel, or other products.
Self-Adhesive Electrodes
It is recognized that there are many brands, types, and styles of electrodes available. We recommend only using
the repositionable LSI Silver Tab self-adhesive electrodes! We do not recommend using foilbacked electrodes or
any kind of expired electrodes. The metal foil can cause changes in the waveform. To ensure maximum life of
your electrodes, the skin should always be cleaned before applying the electrode. This can be accomplished by
stripping with tape, cleansing with soap and water, or by using an alcohol wipe. Electrodes must also be replaced
into the resealable package after use. This will keep them from drying out and losing their adhesive and conduc-
tive properties. Additional life may be added to the electrode by the use of Electro-Mist spray.
A small amount on the electrode before replacing it in the package may reintroduce some adhesiveness and
conductivity. Remember, however, they are “disposable electrodes” and are not intended for indenite use. If you
notice uctuating delivery of current to the patient, poor adhesiveness or difculty in getting the amplitude of
your unit high enough, discard the electrodes and use a new package.
