Introduction
Thank you for buying the GO2Achieve 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 GO2Achieve is easy to use and needs no
routine maintenance except battery replacement. This User Guide explains how to use and
care for your GO2Achieve.

ENGLISH
Intended Use
GO2Achieve 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 – 2.5 cm) thick. The index finger
(pointer finger) is most recommended.
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.
• Before changing batteries, make sure the GO2Achieve is off and is not applied to a
digit.

5
Cautions
• The GO2Achieve might misinterpret excessive movement as good pulse strength. Limit
finger movement as much as possible when using the device.
• The GO2Achieve 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 GO2Achieve 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 GO2Achieve 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 GO2Achieve:
– 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.

ENGLISH
• The GO2Achieve may not work if you have poor circulation. Rub your finger to
increase circulation, or place the device on another finger.
• The GO2Achieve 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 GO2Achieve will be stored for more than 30 days.
• Do not use the GO2Achieve in a combustible environment (oxygen enriched
environment).
• Do not use the GO2Achieve outside the specified operating and storage temperature
ranges.
• Do not use the GO2Achieve for more than 30 minutes without relocating the device
to another finger.
• The GO2Achieve needs to be used according to information provided in the User
Guide.
• Do not tamper with, or hang lanyard from the flexible circuit.

7
• When using the GO2Achieve in the home, avoid exposing the GO2Achieve to lint and
dust.
• 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 GO2Achieve and its components,
including the battery.
• The GO2Achieve is a precision electronic instrument and must be repaired by Nonin
Technical Service.

ENGLISH
Installing the Battery
One 1.5 volt AAA-size (LR03) battery powers the GO2Achieve for approximately 2400
measurements. Nonin recommends using alkaline batteries (one is included with each
new GO2Achieve). 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 GO2Achieve by sliding it
towards you.
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).

3. Carefully reposition the battery door. NOTE: Do not force it into place; it fits only when
positioned correctly.
When battery is low, the battery indicator symbol on the display will flash. Remove battery if
the device will be stored for more than 30 days. Replace low battery as soon as possible.

ENGLISH
Applying the GO
2Achieve to Your Finger
Hold the GO2Achieve with the display
facing toward you; slide your finger into
the opening at the bottom of the device, as
shown at right, until the fingertip touches
the built-in stop guide. The index (pointer)
finger is recommended.
Have your forearm parallel to the floor when
you use the GO2Achieve. Make sure your
finger is centered within the finger guide
and the GO2Achieve is at heart or chest
level.

NOTE: Correct positioning of the device on your finger is critical for accurate measurements.
While on the finger, do not press the GO2Achieve against any surface and do not squeeze
or hold it together. The internal spring provides the correct pressure; additional pressure may
cause inaccurate readings.

ENGLISH
Activating the Device
The GO2Achieve automatically turns on when a finger
is inserted. When a finger is inserted, the GO2Achieve
performs a brief self test, as shown at right. Verify that
all segments of the LCD (Liquid Crystal Display) appear
during the startup sequence.’
Verifying Operation
The GO2Achieve LCD has an integrated backlight that
turns on automatically in low light conditions. This allows
the display to be visible in dark spaces.
If the GO2Achieve does not turn on or if it shuts off
unexpectedly, remove the GO2Achieve from your finger,
remove the battery, and see the Troubleshooting section.
Continually verify operation.

Reading Your Results
When you put your finger in the GO2Achieve, you’ll notice an LCD display come on. The
numbers you see show:
• the amount of oxygen in your blood, displayed as %SpO2; and
• your Pulse Rate, displayed as a 2 or 3 digit number, measuring the number of times your
heart beats per minute.
The Pulse Quality indicator ( ) displays the strength of the pulse rate signal. Bars will
display after the , indicating pulse signal strength ( ); the greater the number of
bars indicates a greater pulse quality signal strength.
If you are not getting a pulse rate reading and your pulse quality indicator is weak, warm
the finger or reposition to another finger.
While the GO2Achieve is calculating its reading immediately after activating the device, the
sensor disconnect indicator ( ) will appear. The sensor disconnect indicator also appears
when you remove your finger to indicate the pulse signal is not detected or when there is

excessive motion. If this symbol does not turn off while your finger is in the device,
reposition your finger or switch to a different finger.
The Battery indicator symbol shows the battery strength (the less the symbol is
filled – the less battery capacity is available – see chart below). Replace the battery when
this symbol begins to flash.

Care and Maintenance
The GO2Achieve requires no calibration or periodic maintenance other than battery
replacement.
Wipe the device with a soft cloth dampened with a mild detergent or 10% bleach solution.
Do not use undiluted bleach or any cleaning solution other than those recommended here,
as permanent damage could result. Dry with a soft cloth, or allow to air dry.
Clean once per week or more frequently if handled by multiple users.
Caution: Do not place the GO2Achieve in liquid or clean it with agents containing
ammonium chloride, isopropyl alcohol, or products that are not listed in this User’s Guide.
