1.2.2. The chest strap (continuation of strap instructions)
Important: heartrate can only be measured using the Keymaze 700.
Normal conditions of use
The chest strap must be positioned around your thorax (chest). When correctly placed, it sends
heartrate information to the watch. When placed in the cradle (see diagram), the watch displays your
heartrate in order to control and optimise your fitness or training programme.
Restriction on use
The chest strap does not have a coded transmitter.
i heartrate measurement can be influenced by electromagnetic fields (high-voltage power lines, electric fencing, etc). Other heartrate monitor users within 1
metre of you may also cause interference. Move away from any sources of disturbance.
