FRONT PANEL CONTROLS
Power
Pushbutton that activates the monitor. When depressed, the monitor performs a self test and a green light next to the pushbut-
ton illuminates. The recorder remains active following completion of power up self test.
UA Reference
Pushbutton that sets the pressure level on the UA channel at 10 for the tocodynamometer. To activate, depress and hold for 1
second. The chart paper will automatically be annotated. If pressure falls below 0, automatic UA reference will occur and
new baseline reference is set at 0.
In the SET TIME/DATE mode the successive depression of the UA Reference pushbutton permits selection of the time or
date parameter to be changed. o
Volume
Two pushbuttons used to change the volume of sound emitted by the speaker. Depressing the button with the arrow pointing
down causes the volume to decrease. Depressing the button with the arrow pointing up causes the volume to increase. Vol-
ume has no effect on the processing used to compute heart rate.
In the SET TIME/DATE mode, the arrows are used to increase or decrease the time/date parameter selected by the UA
Reference pushbutton.
Mark
When depressed, this pushbutton causes an arrow shaped mark to be printed on the strip chart recorder paper. The Mark
pushbutton is typically used to show where a specific event occurred on the strip chart paper.
Paper Advance
When depressed, chart paper will advance at a speed of 25 cm/min. The recorder will not print during this time.
Record
When depressed, this pushbutton activates the recorder. Once the recorder is activated, depressing Record again turns it off.
A yellow light next to the Record pushbutton will be illuminated when the recorder is activated and turned off when the
recorder is deactivated.
