Ear sensor
Various ear sensors that exist on the market can be connected to the Crosswalker.
However, the Enraf-Nonius program does not include ear sensors since we can not guarantee proper
functioning of such sensors when measuring heart rate frequency.
For accurate heart rate measurement we strongly advise our users to make use of the Polar® chest belt
(optional accessory).
After usage, clean the sensor according to the instructions of the manufacturer.
For most sensors a mild soap solution is sufficient. Do not use detergents!

Chest strap
While training on the Crosswalker, a Polar® heart rate monitoring system can also be used. The Polar®
heart rate monitoring system consists of a lightweight transmitter strap worn round the chest and a
receiver which is inserted into the control panel of the Crosswalker. The transmitter uses two electrodes
to record each heartbeat and then sends the signals to the receiver. During a training session the heart
rate appears in the upper right-hand corner of the screen.
Use the chest strap to measure your heart rate as follows:
Disconnect the ear sensor from the control panel. If you do not do so then there will be no
telemetric monitoring via the chest strap.
The chest strap works best if the transmitter is worn against the bare skin. If you prefer to wear the
transmitter over a shirt then you must also moisten the part of transmitter the where the grooved surfaces
rest against the shirt.
Maintenance of the chest strap:

Use the ear sensor to measure your heart rate as follows:
•
Attach the ear sensor to your ear lobe.
•
Attach the collar clip to your collar or shirt. This stops the sensor from
moving or being disturbed during use. The wire of the ear sensor must be
sufficiently long.
•
The sensor can be attached to the ear lobe or (even better) can be
inserted into the shell of the ear.
1. Attach the transmitter to the elastic band
2. The chest strap must be comfortable and must fit the user's chest snugly
3. Moisten the grooved rear surface of the transmitter, where the electrodes
are located
4. Check that the part with the transmitter is positioned correctly, i.e.
on the right-hand side with the Polar logo in the middle
Clean the transmitter after use with a mild soap solution
Rinse with clean water
Dry the transmitter thoroughly, otherwise the internal batteries will run down
