Controls, Indicators, and Connectors: Front Panel Controls
UA Reference Button
The UA Reference button is used to set the uterine activity pressure reference. This
button is also used during setup.
Setting a Baseline for External Monitoring (Tocotransducer)
Briefly pressing the UA Reference button sets the pressure baseline at a preset
default. The monitor is shipped from the factory with a default setting of 10 relative
units. Qualified service personnel can access a service screen to set the default to 5,
10, 15, 20, or 25 relative units.
Pressing this button for more than two seconds causes the uterine activity reference
value to override the default setting and cycle through all available selections: 5, 10,
15, 20, or 25 relative units, starting at the
default setting—until the button is
released. While the button is held down, the strip chart tracing remains unchanged.
Once the button is released, the recorder trace takes on this new value. This value is
stored as the new baseline for the currently measured uterine activity signal.
Setting a Baseline for Internal Monitoring (IUPC)
Pressing the UA Reference button sets the pressure baseline at 0 mmHg.
NOTE:
IUPC monitoring is only available on Models 173 and 174.
Setup Mode
When the monitor is in setup mode, the UA Reference button selects the active
display. Pressing the button alternates between the UA display (which shows a
monitor feature code) and the FHR display (which shows the setting or value for the
selected feature code). When the UA display is active, the ± sign lights. When the
FHR display is active, the heartbeat indicator
lights.
Alarm Silence Button
This button is yellow for easy recognition. Pressing the Alarm Silence button
removes the audible indication of an individual fetal heart rate alarm.
NOTE:
Silencing an alarm does not affect the visual indications.
