oxygen level by shining light into the skin and checking how
much light is absorbed. This is referred to as SpO
2
.
On the device, your pulse oximeter readings appear as an SpO
2
percentage. On your Garmin Connect account, you can view
additional details about your pulse oximeter readings, including
trends over multiple days. For more information on pulse
oximeter accuracy, go to
.
Getting Pulse Oximeter Readings
You can manually begin a pulse oximeter reading by viewing the
pulse oximeter widget. The accuracy of the pulse oximeter
reading can vary based on your blood flow, the device
placement on your wrist, and your stillness.
NOTE:
You may need to add the pulse oximeter widget to the
widget loop.
1
While you are sitting or inactive, swipe up to view the pulse
oximeter widget.
2
Tap the widget to view more details and begin a pulse
oximeter reading.
3
Hold the arm wearing the device at heart level while the
device reads your blood oxygen saturation.
4
Keep still.
The device displays your oxygen saturation as a percentage,
and a graph of your pulse oximeter readings and heart rate
values for the last four hours.
Tips for Erratic Pulse Oximeter Data
If the pulse oximeter data is erratic or does not appear, you can
try these tips.
• Remain motionless while the device reads your blood oxygen
saturation.
• Wear the device above your wrist bone. The device should
be snug but comfortable.
• Hold the arm wearing the device at heart level while the
device reads your blood oxygen saturation.
• Use a silicone band.
• Clean and dry your arm before putting on the device.
• Avoid wearing sunscreen, lotion, and insect repellent under
the device.
• Avoid scratching the optical sensor on the back of the device.
• Rinse the device with fresh water after each workout.
Activities and Apps
Your device can be used for indoor, outdoor, athletic, and fitness
activities. When you start an activity, the device displays and
records sensor data. You can save activities and share them
with the Garmin Connect community.
You can also add Connect IQ activities and apps to your device
using the Connect IQ app (
).

Starting an Activity
When you start an activity, GPS turns on automatically (if
required).
1
Press the action button.
2
Select .
3
Select an activity.
4
If the activity requires GPS signals, go outside to an area with
a clear view of the sky, and wait until the device is ready.
The device is ready after it establishes your heart rate,
acquires GPS signals (if required), and connects to your
wireless sensors (if required).
5
Press the action button to start the activity timer.
The device records activity data only while the activity timer is
running.

Indoor Activities
The Approach device can be used for training indoors, such as
running on an indoor track or using a stationary bike. GPS is
turned off for indoor activities.
When running or walking with GPS turned off, speed, distance,
and cadence are calculated using the accelerometer in the
device. The accelerometer is self-calibrating. The accuracy of
the speed, distance, and cadence data improves after a few
outdoor runs or walks using GPS.
TIP:
Holding the handrails of the treadmill reduces accuracy.
You can use an optional foot pod to record pace, distance, and
cadence.
When cycling with GPS turned off, speed and distance are not
available unless you have an optional sensor that sends speed
and distance data to the device (such as a speed or cadence
sensor).
Calibrating the Treadmill Distance
To record more accurate distances for your treadmill activities,
you can calibrate the treadmill distance after you travel at least
1.5 km (1 mi.) on a treadmill. If you use different treadmills, you
can manually calibrate the treadmill distance on each treadmill
or after each activity.
1
Start a treadmill activity (
), and
travel at least 1.5 km (1 mi.) on the treadmill.
2
After you complete your activity, press the action button, and
select
Done
.
3
Check the treadmill display for the distance traveled.
4
Select an option:
• To calibrate the first time, select
Save
, and enter the
treadmill distance on your device.
• To manually calibrate after the first-time calibration, select
>
Calibrate
, and enter the treadmill distance on your
device.
