Recharge the heart rate sensor for first time use or after long period of storage:

The voltage of the internal rechargeable battery may drop due to self-discharge during long period of storage. Always fully charge the heart rate sensor before use.

Cautions for charging and usage:

• Before charging, make sure no dust or other foreign objects are attached to the charging cradle contacts.

• Do not subject the heart rate sensor to vibrations while charging.

• When your PC is in the sleep state, the heart rate sensor cannot be charged.

• Once charging is complete, be sure to remove the heart rate sensor from the charging cradle.

• The standard charging time and continuous operating time are approximate and will vary according to environmental and usage conditions.

• Charging, discharging, and storing in high temperatures will cause the internal rechargeable battery to deteriorate faster. Do not place the heart rate sensor inside a vehicle or near a heater. Make sure to charge only when the ambient temperature is between 41°F and 104°F (5°C and 40°C).

• If the operating time is significantly reduced even after proper charging, the heart rate sensor may be nearing the end of its service life due to degradation of the internal rechargeable battery.

Cautions on storage:

• If the heart rate sensor will not be used for a long period of time, store it in a location that is not too hot or too humid.

• Charge the heart rate sensor for about 30 minutes every 6 months.

Cautions for dispose:

Dispose of the heart rate sensor appropriately according to local regulations.
