Bluetooth
This handset communicates with wireless devices on Industrial, Scientific &
Medical (ISM) radio bands, used by electrical appliances (microwave ovens), as
well as license-free, error-tolerant communications applications, cordless phones,
amateur radio stations, etc. (hereafter "other radio stations").
Before handset use, be sure "other radio stations" are not in use nearby.
When radio interference occurs, change location or turn handset off.
Use near TVs or radios may cause noise or connection failure.
Electrical appliances, especially microwave ovens may hamper connections.
Strong RF emissions may hamper connections.
Objects placed between devices may affect connections.
