Introduction
Thank you for buying the GO2 LED Achieve Fingertip Pulse Oximeter. This small, portable
device will give you important information about your oxygen saturation (the amount of
oxygen in your blood) and pulse rate at your fingertip! The GO2 LED Achieve is easy to use
and needs no routine maintenance except battery replacement. This User Guide explains
how to use and care for your GO2 LED Achieve.

Intended Use
GO2 LED Achieve is intended to measure blood oxygen saturation (%SpO2) (the amount
of oxygen in your blood) and pulse rate of both adults and children. It is designed for
fingers (not the thumb) between 0.3 and 1.0 inch (0.8 – 2.5cm) thick.
Warnings
• Keep the oximeter away from young children. Small items such as the battery door,
battery, and lanyard are choking hazards.
• Certain activities may pose a risk of injury, including strangulation, if the lanyard
should become wrapped around your neck. Use the lanyard with caution.

Cautions
• The GO2 LED Achieve might misinterpret excessive movement as good pulse strength.
Limit finger movement as much as possible when using the device.
• The GO2 LED Achieve must be able to measure your pulse properly to give you an
accurate reading. Do not put the device on the same hand/arm when using a blood pressure
cuff or monitor.
• The GO2 LED Achieve has no alarms. It will not sound if the amount of oxygen in your
blood is low or if your pulse rate is too high or too low.
• Do not place the GO2 LED Achieve in liquid or clean it with agents containing
ammonium chloride, isopropyl alcohol, or products that are not listed in this User’s Guide.
• Any of the following conditions may reduce the performance of the GO2 LED Achieve:
– flickering or very bright light;
– weak pulse quality (low perfusion);
– low hemoglobin;
– arterial catheters;
– nail polish, and/or artificial nails; and
– any tests recently performed on you that required an injection of intravascular dyes.
• The GO2 LED Achieve may not work if you have poor circulation. Rub your finger to
increase circulation, or place the device on another finger.
• The GO2 LED Achieve measures oxygen saturation of functional hemoglobin. High
levels of dysfunctional hemoglobin (caused by sickle cell anemia, carbon monoxide,
etc.) could affect the accuracy of the measurements.
• Batteries can leak or explode if used or disposed of improperly. Remove the battery if
the GO2 LED Achieve will be stored for more than 30 days.
• Do not use the GO2 LED Achieve in a combustible environment (oxygen enriched
environment).
• Do not use the GO2 LED Achieve outside the specified operating and storage
temperature ranges.
• Do not use the GO2 LED Achieve for more than 30 minutes without relocating the
device to another finger.
• The GO2 LED Achieve needs to be used according to information provided in the
User Guide.
• Do not tamper with, or hang lanyard from the flexible circuit.

ENGLISH
• Radios and cell phones or similar devices may affect the GO2 LED Achieve and should be
kept at least 7 feet away from the device.
• Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast towers
and TV broadcast towers may affect accuracy.
• Use in emergency vehicles with communication systems may affect accuracy.
• Functional tester cannot be used to assess the accuracy of this pulse oximeter.
• Follow local disposal and recycling laws for the GO2 LED Achieve and its components,
including the battery.
• The GO2 LED Achieve is a precision electronic instrument and must be repaired by Nonin
Technical Service.
Installing the Battery
One 1.5 volt AAA-size (LR03) battery powers the GO2 LED Achieve for approximately
2,400 measurements. Nonin recommends using alkaline batteries (one is included with
each new GO2 LED Achieve). NOTE: You may use rechargeable batteries; however, they
may require more frequent replacement.
1. Remove the battery door located on the left side of the GO2 LED Achieve by sliding
it towards you (see page 9 diagram).
2. Insert one new 1.5 volt AAA-size battery. Follow the plus (+) and minus (-) markings
for battery direction (as shown inside of the battery compartment).
