1. EXPLANATIONS OF OPERATING CONTROLS
FRONT PANEL
See fig. 1.1
1.1 POWER SWITCH
The power switch is an alternate position switch. When activated it connects both the hot
and the neutral into the power circuits.
1.2
IMPEDANCE SWITCH
The impedance switch is a momentary switch. When depressed, it signals the processor to
start the impedance test sequence. After a second, an impedance readout is displayed. The
display is on for the duration of the switch activation.
1.3
IMPEDANCE/TIME READOUT
The impedance readout is an 8 digit alphanumeric LED (Light Emitting Display) which
indicates the impedance of the stimulus electrodes when the impedance test switch is
depressed. If the impedance is over 3000 Ohms the display blinks. After the treatment is
delivered the same 8 digit LED is used to display time elapsed since the end of treatment.
It is also used during the Flexdial setup mode to alter parameters.
1.4
PERCENT ENERGY READOUT
The percent energy readout is a 4 digit alphanumeric LED (Light Emitting Display) which
indicates the setting of the energy dial. It is also used to indicate the treatment program
that is being used.
1.5
DOSAGE ADJUSTMENT DIAL
The dosage adjustment dial sets the number of pulses in the stimulus pulse train. It's a
continuously rotating optical encoder. In the default program setting of LOW 0.5 the
lowest setting gives 28 pulses. Each increase in the setting of the dial adds 28 more pulses
to the stimulus. The maximum setting is 560 pulses. The dial is calibrated in PERCENT
ENERGY of its maximum for ease of use. After each change there is 1 second display of
the millicoulomb value before the display returns to the percent display. If the dial is
pressed the display will indicate the treatment program that is being used.
1.6
TREAT SWITCH
The TREAT switch is a momentary switch which controls the delivery of the stimulus. It
has a special protective cover which prevents accidental activation. As an additional safety
feature there is a one second warning tone before the stimulus begins whenever the
TREAT button is depressed. The yellow indicator light inside the button lights up only
when the electrical stimulus is being delivered. The switch must be depressed for the
duration of the stimulus. The delivery of the stimulus is indicated by the TREAT button
light and a warbling sound. If the button is released, the stimulus will be immediately
terminated.
