1. Connect pads cable to the back of therapy connector on the back of Responder 2000.
2. Connect pads to a Calibrated Impulse 4000 Defib/Pacer Analyzer or equivalent.
3. Turn on the Responder 2000.
4. Use Rotary Selector Knob to move focus to and select Pacing Info box in the lower right of the display.
Note: If pacing is not enabled, the Pacing Info box is not selectable.
5. Turning the Rotary Selector Knob clockwise, the following items should be selectable::
Pacing Type (Fixed, Demand), Default is Demand.
•
PPM ( 30-180 PPM, increments of 5), Default is 60 PPM
•
Exit Pacing Info Box ("x" in corner)
•
Pacing On/Off/Pause (Pause is only available when Pacing is turned On)
•
Pacing Current (0mA-140mA, increments of 5). This option is only selectable when pacing is turned on.
•
6. Turn the Rotary Selector Knob to turn on the pacing.
7. When Pacing is turned on, focus automatically goes to the Pacing Current selection. Set desired pacing
