Technical Information

1
Measurement of parameters
Stopwatch, heart rate (BPM and %HRmax), current and total calorie expenditure.
2
Target zones
You can manage your training session better by adjusting the target zone settings. A graphic indicator shows you, in real time, whether you are in the exercise zone that you have set. The ONrhythm 500 allows you to set the heart rate target zones (in BPM or %HRmax).
3
Training intensity indicator
The ONrhythm 500 indicates, automatically and in real time, the intensity of your exercise according to your heart rate: very light, light, moderate, hard or very hard training.
4
INTERVAL TRAINING
Using this function, you will be able to programme a complete interval training session: warm-up time, activity time, rest time and easing off time, number of series of interval runs and rest time between series.
5
Stopwatch with split times (lap)
The split time stopwatch enables you to measure several time intervals during a session. You will thus be able to measure your progress over set intervals.

Time
Time, date, alarm, back-lighting

Difficult to connect!
Used for 2 to 8 weeks
It always took me sooooo long to connect! Once it is connected, it will hang after around ten mints and connect again! So difficult to use!
Response of the brand
Hi,

I'm sorry to hear that you have had issues connecting to your Onrhythm500 HRM.

There are two points you can check:

Do you moisten the sensors on your belt?
Is the batter well charged?

Kind regards,
