6. 2.4GHztransmission frequency function
Two ways RF, CRC check, data loss or errors of software
re_send, ensuring more
reliable transmission.
Working voltage range: 1.9-3.6y
Working chann ell. 2.402G - 2.4gOG,
Channelinterval: lM
channel hopping will not less than I2 (totar g0 channels
available, according to
software optimization algorithm, expect disturbed
channer, optimize to choo.",,or"
I 2 clear channels ) sub-channel divide l M,
the max transmission data is r M, power
density is about lMdm. Above all technorogy index
aI meet FCC and Europe ETSI
standard. Green transmission technology can be used
all over the world.
Transmission speed lM bps
Modulate way GFSK
Frequency hopping FHSS
Receiving sensitivity: -85dBm
Transmission power: 0dBm
7. Change battery
when usB receiver connects keyboard on-line mode normally,
and the low voltage LED
light blinks, it means the battery power is not enough. you
need change battery. when
changing the battery, please reference to the user
manual 2.
