Maintenance
The chest sensor and its elastic strap should be rinsed in fresh water to avoid the
buildup of materials that can interfere with the measurement of your Heart Rate.
The watch monitor does not need to be rinsed.
1. Do not clean the chest sensor with abrasive or corrosive materials. Abrasive
cleaning agents may scratch the plastic parts and corrode the electronic
circuit.
2. Do not subject the sensor to excessive force, shock, dust, temperature, or
humidity. Such treatment may result in malfunction, a shorter electronic life
span, damaged batteries, or distorted parts.
3. Do not tamper with the sensor's internal components. Doing so will terminate
the sensor's warranty and may cause damage. The sensor contains no
user-serviceable parts.

Battery Information
This product uses a CR2032 lithium battery for the sensor and a CR2025 lithium
battery for the watch.
When the battery of the watch is running low, the display will dim.
If the Heart Rate readings become erratic or stop, your chest sensor battery may
need replacing. You can do this by yourself very easily without any special tools.
