put it in a place that will not squeeze it; extrusion may result in product damages or personal

Bluetooth technology is a wireless short-distance communication technology. Bluetooth
products run in the industrial, scientific and medical (ISM) frequency bands used worldwide, and
frequency hopping technology is adopted in order to avoid interference, which divided 2.4ghz and
2.4835ghz into 79 channels to transmit data at the frequency hopping rate of 1600 times per
second with about 10 meters of transmission distance (Class?). The bluetooth headset published
from Lenovo can communicate with other bluetooth devices within a range of about 10 meters (33
feet) without obstacles.
