Important
AMREX Intensity Reset Circuit: The Amrex IF250 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:
• at power on, the Intensity controls are not set to the 0/Reset position enabling
the audible "clicks"
• the treatment period has ended
• the Patient Treatment Stop Switch is activated
• the Reset Functions control is pressed
• the ac power is interrupted
• theQuad-Polar mode Channel1 Intensity setting variesmore than ±20% from
the Channel 2 Intensity setting for longer than 30 seconds
When the Amrex IF250 safety reset functionis 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 "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 TreatmentStop Switchis 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 Channel 1 Intensity and Channel 2 Intensity controls are returned to the 0/Reset position
enabling the audible "clicks", 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.
