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 ratemeasurement, we advise you to wear your OH1 for a few minutes prior to starting the heart ratemeasurement.

WHEN MEASURING HEART RATE FROM YOUR TEMPLE IN SWIMMINGThe OH1 set has been available with two different types of swimming goggle clips. Your set can include twoclips (picture A) or one clip (picture B). Both types of clips are well suited to be worn when swimming, theirdesign is just slightly different. If your set included two clips (picture A), try both to see which one fits yourswimming goggles better and keeps the sensor securely in place on your temple.

10

1. Put the sensor inside the holder with the leds facing your skin and the button facing up.
2. Push the holder as far as it goes so that it sits snugly on the strap.
3. Wear the sensor on your left temple if you breathe in from your left side when swimming freestyle,and vice-versa if you breathe in from your right side.

The sensor must constantly touch the skin of your temple.

PAIRINGPAIR A MOBILE DEVICE WITH YOUR OH1

5. Choose Yes. New firmware is installed (this may take up to 10 minutes). Please wait until thefirmware update has been finalized before you detach the OH1 from your computer.

13

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 andaffected by both internal and external factors—meaning that you will have a dependable measure of yourphysical 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 orwith the swimming goggle strap holder on you temple. The sensor must be in constant touch with your skin,
but the armband should not be too tight to prevent blood flow. The sensor in the swimming goggle strap
holder should be attached as far as you can on your temple without getting your hair between the sensor andyour skin. For most accurate heart rate measurement, we advise you to wear your OH1 for a few minutes
prior to starting the heart rate measurement.

Do not press the sensor button while under water to maintain water resistance.
If you have tattoos avoid placing the sensor right on them 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!
For detailed instructions on wearing OH1, see "Wearing your OH1" on page 10

START A TRAINING SESSION

material (a plastic bag or a sports bag) nor with conductive material (a wet towel). Do not expose the training
device to direct sunlight for extended periods, such as by leaving it in a car. It is recommended to store thetraining device partially or fully charged. The battery slowly loses its charge when it is stored. If you are goingto store the training device for several months, it is recommended to recharge it after a few months. This will
prolong the battery lifetime.
Do not leave the device in extreme cold (below –10 °C/14 °F) and heat (above 50 °C/120 °F) or
under direct sunlight.

SERVICE
During the two-year guarantee/warranty period we recommend that you have service done by an authorized
Polar Service Center only. The warranty does not cover damage or consequential damage caused by service
not authorized by Polar Electro. For further information, see Limited International Polar Guarantee.
For contact information and all Polar Service Center addresses, visit support.polar.com and country-specificwebsites.

PRECAUTIONSThe Polar OH1 is designed to measure heart rate. No other use is intended or implied.

The training device should not be used for obtaining environmental measurements that require professional
or industrial precision.
We recommend that once in a while you wash the device and the armband to avoid any skin problems froma dirty armband.

INTERFERENCE DURING TRAINING
Electromagnetic Interference and Training Equipment
Disturbance may occur near electrical devices. Also WLAN base stations may cause interference whentraining with the training device. To avoid erratic reading or misbehavior, move away from possible sourcesof disturbance.
Training equipment with electronic or electrical components such as LED displays, motors and electricalbrakes may cause interfering stray signals.
If the training device still does not work with the training equipment, it may be electrically too noisy for
wireless heart rate measurement. For further information, see www.polar.com/support.

MINIMIZING RISKS WHEN TRAINING
Training may include some risk. Before beginning a regular training program, it is recommended that you
answer the following questions concerning your health status. If you answer yes to any of these questions,
we recommend that you consult a doctor before starting any training program.

• Have you been physically inactive for the past 5 years?
• Do you have high blood pressure or high blood cholesterol?
• Are you taking any blood pressure or heart medication?
• Do you have a history of breathing problems?
• Do you have symptoms of any disease?
• Are you recovering from a serious illness or medical treatment?
• Do you use a pacemaker or other implanted electronic device?
• Do you smoke?
• Are you pregnant?
Note that in addition to training intensity, medications for heart conditions, blood pressure, psychologicalconditions, asthma, breathing, etc., as well as some energy drinks, alcohol, and nicotine may also affectheart rate.
It is important to be sensitive to your body’s responses during training. If you feel unexpected pain orexcessive fatigue when training, it is recommended that you stop the training or continue at alighter intensity.
Note! If you are using a pacemaker, you can use Polar products. In theory interference to pacemaker caused
by Polar products should not be possible. In practice no reports exist to suggest anyone ever having
experienced interference. We cannot however issue an official guarantee on our products’ suitability with all
pacemakers or other implanted devices due to the variety of devices available. If you have any doubts, or if

22

you experience any unusual sensations while using Polar products, please consult your physician or contact
the implanted electronic device manufacturer to determine safety in your case.
If you are allergic to any substance that comes into contact with your skin or if you suspect an allergic
reaction due to using the product, check the listed materials in Technical Specifications.

The combined impact of moisture and intense abrasion may cause color to come off the heart rate
sensor’s surface, possibly staining clothes. If you use perfume, suntan/sunscreen lotion or insect repellent
on your skin, you must ensure that it does not come into contact with the training device or the heart rate
sensor. Please avoid clothing with colors that might transfer onto the training device (especially training
devices with light/bright colors) when worn together.
This product is not a toy. Do not allow children or pets to play with this product. This product contains
small components that can be a choking hazard.

WATER RESISTANCE OF POLAR PRODUCTS
Most Polar products can be worn when swimming. They are not, however, diving instruments. To maintainwater resistance, do not press the buttons of the device under water.
Polar devices with wrist-based heart rate measurement are suitable for swimming and bathing. They
will collect your activity data from your wrist movements also when swimming. In our tests, however, wefound that the wrist-based heart rate measurement doesn’t work optimally in water, so we cannot
recommend wrist-based heart rate measurement for swimming.
In the watch industry, water resistance is generally indicated as meters, which means the static waterpressure of that depth. Polar uses this same indication system. Water resistance of Polar products is tested
according to International Standard ISO 22810 or IEC60529. Every Polar device that has water resistanceindication is tested before the delivery to stand water pressure.
Polar products are divided into four different categories according to their water resistance. Check the backof your Polar product for the water resistance category, and compare it to the chart below. Please note thatthese definitions do not necessarily apply to products of other manufacturers.
When performing any underwater activity, the dynamic pressure generated by moving in water is greater than
the static pressure. This means that moving the product under water subjects it to a greater pressure than if
the product were stationary.
