SpO, Warnings
The operation of the SpO; sensor in MRI environments is specifically not recommended.
Use only SpO, sensors and accessories that are compatible with the SpO, configuration
purchased. The Welch Allyn Spot Vital Signs with Nellcor®
pulse oximetry option may only be
used with Nellcor brand sensors and accessories. Other sensors or cables may cause improper
performance.
The SpO, sensors and extension cables are intended for use only for pulse oximetry
measurements. Do not attempt to connect these cables to a PC or any similar device.
Before use, carefully read the sensor's directions for use, including all warnings, cautions, and
instructions.
Do not use a damaged sensor or pulse oximetry cable. Do not use a sensor with exposed optical
components.
Tissue damage is caused by incorrect application or duration of use of an SpO2 sensor. Inspect
the sensor site periodically as directed in the sensor's direction for use.
Pulse oximetry readings and pulse signal is affected by certain ambient environmental
conditions, sensor application errors, and certain patient conditions.
Do not immerse or wet the sensor.
Do not use the pulse oximetry cable or power cord to lift the unit because the cable or cord could
disconnect from the unit, causing the unit to drop on the patient.

Temperature Warnings
Single-use, disposable probe covers, available from Welch Allyn, limit patient cross-
contamination. The use of any other probe cover or the failure to use a probe cover may produce
temperature errors and is specifically not recommended.
Use only oral probes (blue) for taking oral and axillary temperatures. Use only rectal probes (red)
for taking rectal temperatures. The use of the wrong probe may produce temperature errors.
Do not allow the tip of the temperature probe to come into contact with any heat source (e.g.,
hands or fingers) prior to taking a temperature measurement. If this occurs, discard the probe
cover and start the temperature determination again.
A
IR Communications Port Warnings
The Welch Allyn Spot Vital Signs contains an infrared communications port for isolated
communications with external devices. The port is located on the side of the device to preclude
direct eye contact on a continual basis when viewing the display. As a precaution, do not look
directly into the infrared port during operation.
A
General Cautions
If the accuracy of any measurement is in question, check the patient's vital sign(s) by an alternate
method, then check to make sure the device is functioning properly.
Ensure the device is placed on a secure surface or use one of the optional mounting accessories.
Do not place fluids on the device.
