Charge batteries in temperatures from 0°C to 40°C (32°F to 104°F). The device or cradle always performs battery charging safely. At higher temperatures (e.g. approximately +37°C (+98°F)), the device or cradle may charge for small periods of time, or enable and disable battery charging to keep the battery at acceptable temperatures. The device and cradle indicate when charging is disabled due to abnormal temperatures with LED indications.
