TRM 211 Owner's Manual
To ensure a more accurate heart rate readout, follow
these tips:
Grip the sensors with both hands.

Wait at least 10 seconds for your heart rate to

register.
When gripping the sensors, do not grip tightly.

Keep a loose, cupping hold. Holding the grips too
tightly can affect the reading.
As you work out, your perspiration will help

transmit your heart rate signal. If you have
difficulty using the touch-sensitive grips to
determine your heart rate, try the sensors again
later in the workout to see if you can obtain a heart
rate signal.
