In Reply:-In August of 1996 Life-Tech's instrument testing procedures determined that instruments of the lot that was being tested was found to have the problem Dr. Hadzic describes. The engineering team was alerted and the problem was quickly eliminated with an addition of a capacitor change.
It was determined that a recall was not necessary because the problem posed no danger to patients. We have and continue to add the modification to instruments returned to Life-Tech. All instruments with this defect, whether or not it is returned for this complaint, have been modified at no charge to the customer.
This inconsistency was only in the DualStim Deluxe, model NS-2CA/DX and was eliminated in instruments manufactured after August 16, 1996. Due to the inability to no longer obtain metal cases for the DualStim, it has since been replaced with newly introduced MaxiStim and EZStim.
Customers experiencing this the problem described by Dr. Hadzic can call Life-Tech's service department at 1-800-231-9841.
