POLAR OH1 USER MANUAL
This user manual helps you get started with your new OH1. To see OH1 video tutorials and FAQs, go to
support.polar.com/en/OH1.
INTRODUCTION
Congratulations on your new Polar OH1! The Polar OH1 is an optical heart rate sensor that is worn around
your forearm or upper arm. It can be used as a independent training device that records and stores data or as
a heart rate sensor with a Polar wrist unit
GET CONNECTED TO THE POLAR ECOSYSTEM AND GET THE
MOST OUT OF YOUR OH1.
Get the Polar Flow app from the App Store®or Google PlayTM. Sync your OH1 with the Flow app after
training, and get an instant overview and feedback of your training results and performance.
Sync your training data to the Polar Flow web service with the FlowSync software on your computer or via
Flow app. In the web service you can plan your training, track your achievements, get guidance and see
detailed analysis of your training results. Let all your friends know about your achievements, find fellow
exercisers and get motivation from your social training communities. Find all this at flow.polar.com.
SETTING UP YOUR OH1
We recommend that you charge the battery before you start using your OH1. If the battery is completely
empty, it takes a couple of minutes for the charging to start.
See Batteries for detailed information on charging the battery.
CHOOSE ONE OPTION FOR SETUP
A. Wired computer setup is quicker and you can charge your OH1 at the same time, but you need a computer
available. This method requires an Internet connection.
B. Mobile setup is convenient if you don't have access to a computer with a USB port, but it might take longer.
This method requires an Internet connection.
The A and B options are recommended. You can fill in all the physical details required for accurate
training data at once. You can also choose language and get the latest firmware for your OH1.

OPTION A: SET UP WITH YOUR COMPUTER VIA FLOWSYNC
1. Place the sensor into the holder with the lens facing up so that the contacts on the sensor and holder
meet (picture 1).
2. Plug the holder into your computer USB port (picture 2), and go to flow.polar.com/start and install
Polar FlowSync data transfer software to your computer.
3. Sign in with your Polar account or create a new one. We’ll walk you through the sign-up and setup

OPTION B: SET UP WITH YOUR MOBILE DEVICE VIA FLOW APP
Polar OH1 connects to the Polar Flow mobile app wirelessly via Bluetooth, so remember to have Bluetooth
turned on in your mobile device.

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.
Place the sensor into the armband holder with the lens facing up. Wear the armband so that the sensor is on
the underside of the armband firmly against your skin. Wear 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.

UPDATING THE FIRMWARE
You can update the firmware of your OH1 yourself to keep it up to date. 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.
WITH MOBILE DEVICE OR TABLET
You can update the firmware with your mobile device if you're using 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 in the OH1 to 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:
1. Plug your OH1 to your computer.
2. FlowSync starts syncing your data.
3. After syncing, you are asked to update the firmware.
4. Choose Yes. New firmware is installed (this may take up to 10 minutes). Please wait until the firm-
ware update has been finalized before you detach the OH1 from your computer.
