FCC ID: EMJMN3902 Report No.: RF990608D09 Operational Description The transmitter of the EUT (Lenovo Wireless Mouse N3902) is powered by 3Vdc from batteries. The type of antenna is Printed Antenna. The output power of this device is very low. Under normal use condition, the transmitter and the receiver are quite close, so high EIRP power is neither necessary nor allowed because of interference.
