This is the Polar Verity Sense heart rate monitor. It is an sensor which measures your heart rate through contact with your skin.

Within the Motivate CR+ project we will ask you to wear this monitor every time you do any activity. We use this to look at your activity levels during your time on the trial and throughout cardiac rehab.

This small circle device is the Verity Sense heart rate monitor. This is what measures your heart rate during your exercise sessions. It has a sliver button the side - press and hold the button the turn it on. Opposite the silver button it has an LED light, this light will turn on when the device it on. For more information on using the device during your activity see the 'How do I record a training session?' FAQ.

This is the arm strap, you will need to use this to hold the sensor in place while you are exercising. Have a look at the 'How do I wear the Verity Sense' FAQ for more information on where to put it during your sessions.

This is the charger, it is used to charge the device when the battery is running low. It can plug straight into your computer or into a USB plug. If you need more information on charging, check out the 'How do I charge the Verity Sense?' FAQ.

To measure heart rate accurately, you need to wear the monitor 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 band around your forearm or upper arm.

4.If you have tattoos avoid placing the sensor right on them it as it may prevent accurate readings

The sensor must be in firm skin contact, but not too tight to prevent blood flow. For most accurate heart rate measurement, we advise you to wear your monitor for a few minutes prior to starting the heart rate measurement.

To record your heart rate during a training session please follow the following steps:

1. Turn Verity Sense on by pressing the button.

2. Choose recording mode by pressing the button shortly until the LED.

3. The green LED should be next to the arrow icon & the LED on the side lights up green.

4. After your choice, wait until all six LEDs light up. The sensor is then ready to measure & store your heart rate.

When you have finished recording activity, press and hold the button to turn off the device.

The Polar Verity Sense heart rate monitor has up to 12 hours of run time. We suggest you charge the device after every session.

To charge with your computer, just plug your monitor to your computer or a USB plug following the instructions below:

1.Place the sensor into the USB adapter with the lens facing up so that the contacts on the sensor and USB adapter meet (picture 1).

2.Plug the USB adapter into a computer USB port or USB power wall outlet (picture 2).
