POLAR OH1 USER MANUAL
This user manual helps you get started with your new OH1. For OH1 video tutorials and FAQs, go to
support.polar.com/en/OH1.
INTRODUCTION
Congratulations on your new Polar OH1!
Polar OH1 is a compact optical heart rate sensor that measures heart rate from your arm or temple. It's
versatile and offers a great option to heart rate chest straps and wrist-based heart rate devices. With Polar
OH1 you can broadcast your real-time heart rate to your sports watch, smart watch or Polar Beat or other
fitness app via Bluetooth, and simultaneously to ANT+ devices. Polar OH1 has an inbuilt memory so you
can start your workout with OH1 alone and transfer the training data to your phone afterwards. It comes
with a comfortable machine-washable armband and a swimming goggle strap clip (in Polar OH1 + product
package).
It can also be used with Polar Club, Polar GoFit and Polar Team app.

GET CONNECTED TO THE POLAR ECOSYSTEM AND GET THE MOST OUT OF
YOUR OH1
Get the Polar Flow app or Polar Beat from the App Store®or Google PlayTM. Sync your OH1 with one of the
apps 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
the mobile apps. 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 may take a moment for the charging to start. See Batteries for detailed information on charging
the battery.
Note that when your OH1 battery has enough power it will advertise itself to all compatible receivers
nearby.
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&C. 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.
Fill in all the physical details required for accurate training data at once, and get the latest firmware for
your OH1.
OPTION A: SET UP WITH YOUR COMPUTER VIA FLOWSYNC
1. Place the sensor into the USB adapter
with the lens facing up so that the
contacts on the sensor and the USB
adapter meet (picture 1).
2. Plug the USB adapter 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 within
the web service.
After the setup is done, you’re ready to
go. Have fun!
OPTION B: MOBILE SETUP WITH POLAR FLOW APP WHEN YOU HAVE A POLAR
WRIST UNIT
Polar OH1 connects to the Polar Flow mobile app wirelessly via Bluetooth and ANT+, so remember to have
Bluetooth turned on in your mobile device.

8
ANT+ is by default on when you train and sends your HR signal to compatible devices nearby. You can
turn off ANT+ in the Polar Beat app settings if you want.
Check the Polar Flow app compatibility at support.polar.com.
1. Download the Polar Flow app onto your mobile device.
2. Turn Bluetooth® on, and open Flow app on your mobile device.
3. Turn OH1 on by pressing the button until the LED is switched on, Flow app then prompts you to
start pairing. Accept the pairing request and follow the on-screen instructions.
After the setup is done, you’re ready to go. Have fun!
OPTION C: MOBILE SETUP WITH POLAR BEAT WHEN YOU DON'T HAVE A POLAR
WRIST UNIT
Polar OH1 connects to the Polar Beat mobile app wirelessly via Bluetooth and ANT+, so remember to have
Bluetooth turned on in your mobile device.
ANT+ is by default on when you train and sends your HR signal to compatible devices nearby. You can
turn off ANT+ in the Polar Beat app settings if you want.
Check the Polar Beat app compatibility at support.polar.com.
1. Download the Polar Beat app onto your mobile device.
2. Turn Bluetooth on, and open Beat app on your mobile device.
3. Turn OH1 on by pressing the button until the LED is switched on, find your sensor in the Beat app
settings under HR sensor and tap Pair. Follow the on-screen instructions.
After the setup is done, you’re ready to go. Have fun!
BUTTON FUNCTIONS AND LEDS

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.
1. Place the sensor into the armband holder with the lens facing up.
2. Wear the armband so that the sensor is on the underside of the armband firmly against your skin.
3. 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.
WHEN MEASURING HEART RATE FROM YOUR TEMPLE IN SWIMMING
The OH1 set has been available with two different types of swimming goggle clips. Your set can include
two clips (picture A) or one clip (picture B). Both types of clips are well suited to be worn when swimming,
their design is just slightly different. If your set included two clips (picture A), try both to see which one fits
your swimming goggles better and keeps the sensor securely in place on your temple.
