Polar Comprehensive Guide to Heart Rate Monitor Functions and Battery Care

BATTERIES

TRANSMITTER

The estimated average battery life of Polar WearLink Transmitter is 2 years (1 h/day, 7 days/week) and other Polar transmitters 2,500 hours of use. If your transmitter stops working, it might be due to the battery running out. We recommend that you have the battery replaced by an authorized Polar Service Center only.

You can, however, change the battery of the Polar WearLink Transmitter yourself by following the instructions below. To change the battery, you need a coin.

1.Open the connector’s battery cover by turning it counterclockwise with the coin from the CLOSE position to the OPEN position. The cover pops out a little from its niche.

2.Remove the battery cover from the connector, lift the battery from the niche with your fingers and replace it with a new battery.

3.Place the negative (-) side of the battery against the connector and the positive (+) side against the cover.

4.Put the battery in the connector’s niche and put the cover on so that the arrow points to the OPEN position. Make sure that the cover’s sealing ring is placed correctly in its groove.

5.Gently press the cover deep enough so that its exterior surface is on the same level as the connector’s surface.

6.Turn the cover with the coin clockwise so that the arrow on the cover turns from OPEN to CLOSE. Make sure that the cover is closed properly!

In order to ensure the maximum life span of the connector’s battery cover, open it only when you need to change the battery. We recommend that you change the sealing ring of the battery cover every time you change the battery. You can get these sealing rings from authorized Polar Service Centers.

POLAR WRIST RECEIVER

The estimated average battery life of the Polar wrist receiver is 2 years in normal use (1 h / day, 7 days a week). Note also that excessive use of the backlight and the alarm signals will use the battery more rapidly.

Do not open the Polar wrist receiver yourself. To ensure the water resistance properties and the use of qualified components, the wrist receiver battery should be replaced only by an authorised Polar Service Centre. At the same time a full periodic check of the Polar Heart Rate Monitor will be done.

SERVICE

We recommend that you have all service done by an authorized Polar Service Center only.

Water resistance cannot be guaranteed after unauthorized service.

PRECAUTIONS

USING A POLAR HEART RATE MONITOR IN A WATER ENVIRONMENT

Your Polar Heart Rate Monitor is water resistant to 30 meters/ 100 feet. To maintain the water resistance, do not operate the buttons of the wrist receiver under water.

Heart rate measurement in a water environment is technically demanding for the following reasons:

•Pool water with a high chlorine content and seawater are very conductive. The electrodes of a transmitter may short-circuit, which prevents EKG signals from being detected by the transmitter.

•Jumping into the water or strenuous muscle movement during competitive swimming may cause water resistance that shifts the transmitter on the body to a location where it is not possible to pick up EKG signal.

•The EKG signal strength varies depending on the individual’s tissue composition and the percentage of people who have problems in heart rate measuring is considerably higher in a water environment than in other use.

POLAR HEART RATE MONITOR AND INTERFERENCE

ELECTROMAGNETIC INTERFERENCE Disturbances may occur near high voltage power lines, traffic lights, overhead lines of electric railways, electric bus lines or trams, televisions, car motors, bike computers, some motor driven exercise equipment, cellular phones or when you walk through electric security gates.
