PRECAUTIONS

 

Using Heart Rate Monitor while Cycling

While riding a bike, please keep your eyes on the road to prevent possible accidents and injury.

When using the speed sensor, check that you can turn your handlebar normally and that cable wires for the brakes or gearing do not catch on the sensor. Check also that the sensor does not disturb pedaling or the use of the brakes or gearing.

Using the Polar Heart in a Water Environment

Your Polar S120 is water resistant to 160 feet/ 50 meters.

Your Polar S150 is water resistant to 100 feet/ 30 meters.

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

•Pool water with a high chlorine content and seawater may be very conductive and the electrodes of Polar transmitter may get short circuited and EKG signals cannot be detected by the transmitter unit.

•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 Interferance

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.

Exercise Equipment

Several pieces of exercise equipment with electronic or electrical components such as LED displays, motors and electrical brakes may cause interfering stray signals. To try to tackle these problems, relocate the Polar wrist receiver as follows:

1.Remove the transmitter from your chest and use the exercise equipment as you would normally.

2.Move the wrist receiver around until you find an area in which it displays no stray reading or flashing of the heart symbol. Interference is often worst right in front of the display panel of the equipment, while the left or right side of the display is relatively free of disturbance.

S150, S120 specifications

Polar S120 and S150 are two advanced heart rate monitors designed for fitness enthusiasts and athletes seeking to enhance their training experience. Both devices combine cutting-edge technology and user-friendly features, making them ideal tools for tracking performance and improving health.

The Polar S120 is designed with simplicity and efficiency in mind. It boasts a clear display that makes it easy for users to read their heart rate data in real-time. The S120 tracks heart rate continuously, providing users with insights into their cardiovascular performance during workouts. With a memory capacity for up to 99 training sessions, it allows users to store and review their performance over time, making it easier to assess progress and set future goals.

One standout feature of the S120 is its built-in calorie expenditure calculation, which helps users understand how many calories they are burning during their workouts. This is particularly beneficial for those who are aiming to manage their weight or enhance their fitness levels. The device also features multiple heart rate zones that allow users to tailor their training intensity to meet specific fitness objectives, whether it’s fat burning, improving endurance, or building strength.

On the other hand, the Polar S150 builds on the capabilities of the S120 and introduces additional technological advancements. It offers a more comprehensive training analysis, allowing users to customize their workouts more effectively. The S150 includes advanced features such as interval training support, which lets users perform structured workouts that enhance their speed and endurance.

Moreover, the S150 incorporates the Polar OwnCode technology, which ensures a secure transmission of heart rate data, preventing interference from other heart rate monitors. Both models feature user-replaceable batteries, ensuring longevity and ease of use without the need for frequent replacements.

Durability is a characteristic shared by both the S120 and S150. They are designed to withstand various environmental conditions, making them suitable for outdoor activities. Additionally, they are lightweight and comfortable, so users can wear them for extended periods without discomfort.

In summary, the Polar S120 and S150 are excellent heart rate monitors with distinct features tailored for different user needs. The S120 emphasizes ease of use and fundamental tracking, while the S150 offers enhanced capabilities for more serious athletes looking to optimize their training regimens. Together, they represent Polar's commitment to providing tools that support fitness goals through technology and innovation.
