Contraindications—Warnings—Precautions
THIS INSTRUMENT OPERATES ON 150/230 VOLTS AC, 50/60 Hz. (unless otherwise indicated on
the unit) AND MUST BE PROPERLY GROUNDED FOR SAFETY. The three wire power cord with
"hospital grade" plug should be connected to a GROUNDED AC wall receptacle. It is the personal
responsibility and obligation of the user to insure that this instrument is properly connected to the
AC POWER source before use.
Warning–Risk of burns and fire. DO NOT use near conductive
material such as metal bed parts or innerspring mattresses. Renew
electrode cables upon evidence of deterioration. Use of controls,
adjustment, or performance of procedures, other than those specified
herein, may result in hazardous exposure to electrical energy.
Important
AMREX Intensity Reset Circuit: The Amrex Low Volt AC Stimulator incorporates a unique
safety reset function as part of the intensity controls. This is to prevent any sudden or inadvertent
stimulation output to the patient in the event that:
• The Low Volt AC Intensity controls are not set to the 0/Reset position enabling the
audible/ tactile "clicks" at power on.
• The ac power is interrupted during treatment.
• The treatment period has ended.
• The Patient Treatment Stop Switch is activated.
The Low Volt AC Intensity controls must be returned to the 0/Reset position enabling the audible/
tactile "clicks", a treatment time selected, and the Start Timer control pressed before stimulation
output can be activated.
When the Amrex Low Volt AC Stimulator safety reset function is initiated, stimulator output will
be discontinued immediately, the Reset Intensities indicator light will flash and an audible signal
will be emitted from the generator. The Intensity controls must be returned to the 0/Reset position,
enabling the audible/tactile "clicks", a treatment time selected, and the Start Timer control pressed
before stimulator output can be activated.
Note: The generator will default to factory settings unless the treatment period has ended
without interruption or the Patient Treatment Stop Switch has been activated.
Patient "Treatment Stop" Switch: When the patient "Treatment Stop" switch is activated, stimulator
output will be discontinued immediately. The Reset Intensities indicator light will flash and an
audible signal will be emitted from the generator. Stimulator output cannot be resumed until the
Low Volt AC Intensity controls for Channel A and Channel B are returned to the 0/Reset position
enabling the audible/tactile "clicks" which will turn off the Reset Intensities indicator light, a
treatment time selected, and the Start Timer control pressed. NOW the stimulator output can be
activated.
Note: All generator settings are maintained except the treatment time which reverts to the
factory default setting of fifteen minutes.
