Verifying System Operation - Nonin Avant 4000 Operator's Manual

Using the Avant™ 4000 Digital Pulse Oximetry System

Verifying System Operation

When the display unit is first turned on, it performs a brief startup (initialization)
sequence. Verify that all LEDs illuminate and the unit beeps three times during the
first phase of the startup sequence. If any LED is not lit (except the AC Power
Adapter LED), do not use the device. Contact your distributor or NONIN
Customer Support for assistance.
After this initialization sequence, the amber Connection Status LED and amber
dashes are displayed, turning green when communication is established and a
Bluetooth connection is made (devices must be paired before a Bluetooth
connection can be established; see "Device Pairing" on the next page). The Main
Alarm LED and Pulse Oximeter LED blink amber until the oximeter produces valid
readings.
Use the procedure below to monitor SpO
that the device is functioning properly.
1. Ensure that the display unit is turned on, and that the unit has been paired
with the desired wrist-worn patient module. (See "Device Pairing" for more
information.)
2. Connect a sensor to the patient module, pressing firmly to make sure it is
securely connected.
3. Apply the patient module around the wrist, and attach the sensor to the
patient's finger. Connecting the sensor automatically activates the patient
module; there are no buttons to press.
4. Verify that the Connection Status LEDs on both the display unit and the
patient module are green.
5. Verify that a good SpO
and that the Pulse Strength Bargraph LED is active.
