Wearing your OH1
When measuring heart rate from your forearm or upper arm
To measure heart rate accurately, you need to wear the OH1 snugly on your
forearm or upper arm, not on your wrist.
1Place the sensor into the armband holder with the lens facing up.
2Wear the armband so that the sensor is on the underside of the armband
firmly against your skin.
3Wear the OH1 around your forearm or upper arm.
The sensor must be in firm skin contact, but not too tight to prevent blood
flow. For most accurate heart rate measurement, we advise you to wear your
OH1 for a few minutes prior to starting the heart rate measurement.
Pairing
Pair a mobile device with your OH1
If you've done the setup for your OH1 with a mobile device as described in
chapter "Setting up your OH1" on page10, your OH1 has already been paired

16
with your mobile device.
If you did the setup with a computer, and would like to use your OH1 with
Polar Flow app you need to perform one training session with OH1 as an
independent training device before it can be paired with Flow app. See
detailed instructions below.
Before pairing make sure:
•You have a Polar account and Flow app.
•Your mobile device has Bluetooth turned on, and airplane mode/flight
mode is not turned on.
•You have performed at least one training session with OH1 as an inde-
pendent training device. For details, see "Start a training session" on
page19
Once all the criteria above is met:
1Sign in to Flow app with your Polar account.
2On OH1, press the button until the LED is switched on, and release. OH1
is now on.
3Flow app automatically prompts you to pair your OH1 with it if it is within
Bluetooth range.
Your OH1 syncs with the Flow app automatically if your phone is within the
Bluetooth range. When your OH1 syncs with Flow app, your training data is also
synced automatically via an internet connection to the Flow web service.
Pair OH1 with a Polar wrist unit
On OH1, press the button until the LEDis switched on, and release. OH1 is

Updating the firmware
You can update the firmware of your OH1 yourself to keep it up to date. You'll
be notified via Flow when a new version is available. Firmware updates are
performed to improve the functionality of your OH1. They can include
improvements to existing features, completely new features or bug fixes. We
recommend that you update the firmware of your OH1 every time a new
version is available.
You won't lose any data due to the firmware update. Before the update begins,
the data from your OH1 is synced to the Flow web service.

18
With mobile device or tablet
You can update the firmware with your mobile device if you're using the Polar
Flow mobile app to sync your training and activity data. The app will let you
know if there's an update available and will guide you through it. We
recommend that you plug the OH1 into a power source before starting the
update to ensure flawless update operation.
The wireless firmware update may take up to 20 minutes, depending on your
connection.
With computer
Whenever a new firmware version is available, FlowSync will notify you when
you connect the OH1 to your computer. The firmware updates are
downloaded via FlowSync.
To update the firmware:
1Place the sensor into the USB adapter with the lens facing up so that the
contacts on the sensor and the USB adapter meet.
2Plug the USB adapter into your computer USB port.
3FlowSync starts syncing your data.
4After syncing, you are asked to update the firmware.
5Choose Yes. New firmware is installed (this may take up to 10 minutes).
Please wait until the firmware update has been finalized before you detach
the OH1 from your computer.

Heart rate training
Although there are many subjective clues as to how your body is doing during
exercise (perceived exertion, breathing rate, physical sensations), none of
them are as reliable as measuring heart rate. It is objective and affected by
both internal and external factors—meaning that you will have a dependable
measure of your physical state.
Measuring heart rate with your OH1
To measure heart rate accurately you need to wear your OH1 snugly around
your forearm or upper arm. The sensor must be in constant touch with your
skin, but the armband should not be too tight to prevent blood flow. For most
accurate heart rate measurement, we advise you to wear your OH1 for a few
minutes prior to starting the heart rate measurement.
If you have tattoos avoid placing the sensor right on them it as it may prevent
accurate readings.
Also it's a good idea to warm up the skin if your hands and skin get cold
easily. Get the blood going before starting your session!
