2.10 Preparing the (optional) CoBex Recorder
a. Installing the Chart Recorder Battery
The seven-day circular chart
recorder is located on the front of
the incubator cabinet and is
protected by a glass door.
To prepare the recorder for
operation, open the glass door
and snap the connector onto the
9-volt battery as shown in Figure
2-3. If the unit is operating, the
green LED lights steady. If the
unit is not turned on, the LED
blinks.
Figure 2-3
If the battery is weak or not connected, the green LED will flash. If power is lost to the
cabinet, the LED will also flash. When replacing the 9-volt battery, use only an alkaline-style
battery.
b. Changing the Chart Paper
1. Press the Change Chart button (#3) and hold it for 1 second until the pen begins to move to
the left of the chart. See Figure 2-3.
2. Remove the existing chart by unscrewing the center knob securing it.
3. Install the new chart, positioning it so that the correct time line coincides with the time line
groove on the chart plate.
4. Replace the center knob and screw it tightly against the chart.
