Directions for Use Introduction 9
General Cautions
A caution statement in this manual identifies a condition or practice, which if not 
corrected or discontinued immediately, could lead to equipment failure, equipment 
damage, or data loss.
These cautions pertain to the entire Spot Vital Signs LXi device.
WARNING Tissue damage can be caused by incorrect application or duration of 
use of a Nellcor OxiMax sensor. Inspect the sensor site as directed in the sensor 
Directions for Use.
WARNING Do not use the sensors during magnetic resonance imaging (MRI) 
scanning. Induced current could potentially cause burns. The MS board pulse 
oximeter may affect the MRI image, and the MRI unit may affect the accuracy of 
the oximetry measurements.
WARNING Carefully route patient cabling to reduce the possibility of patient 
entanglement or strangulation.
WARNING Failure to cover the Nellcor OxiMax sensor site with opaque material 
in high ambient light conditions may result in inaccurate measurements.
WARNING Do not use the pulse oximeter as a replacement or substitute for 
ECG-based arrhythmia analysis. 
Caution If the accuracy of any measurement is in question, check the patient’s 
vital sign(s) with an alternate method and then check to verify the device is 
functioning properly.
Caution Place the device on a secure surface or use one of the optional 
mounting accessories.
Caution Do not place fluids on or near the device.
Caution It is recommended that the device is used within stated operating 
temperature ranges (see “Environmental” on page 59). The device will not meet 
its performance specifications if used outside these temperatures ranges. 
Caution For proper patient electrical isolation, use only a Welch Allyn power 
supply (4500-101A) to charge Spot LXi. Do not use the weight scale 
manufacturer’s charger while the weight scale is attached to the Spot LXi. While 
charging the Spot LXi, it is acceptable to charge the Spot LXi printer with the 
power supply (713703 or BC1300M).
Caution Always unplug the AC power transformer from the outlet before 
moving the mobile stand to a new location.
Caution The basket has a three-pound weight limit. Take care not to exceed 
this limit.
Caution Only use a 9V battery with the Healthometer scale. Remove and 
discard the wall mounted power supply.
Caution When using the Healthometer scale, remove the two hex nuts on the 
RS-232 cable, as supplied, before screwing the cable into the scale base.
