(following the same paring steps )
E. Afte r successf ull y conne ctin g wi th devi ce B, then powe r of f BTI -020V.
F. Power on the device A (do not enter into pairing mode, but if it enters into pairi ng mode , i t’s ok) , arou nd
10-20 seconds later (in this case, most of the Bluetooth speaker is for automaticall y connection, please wait a
m o men t)
Then power on the BTI-020V (no need to enter into pairing mode), it will search and connect with device A
and B automatically, the pairin g time will ta ke around 30 seconds. Then connect to audio resource to check
if the two de vi ces could pl ay sim ultane ousl y. If n ot, pl ease powe r off BTI -020V, and reopen BTI-020V to
co nnect with devi ce A a nd B.
If reopen BTI-020V does no t wo rk, pl ease re work the steps fo r two conne ctio ns si multane ousl y.

Ba t te ry i n fo rma ti on
Your devi ce is powered by a recha rgeable ba tte ry .The full perf ormance of a new ba tte ry is achie ved only
after two of three comple te cha rge and di scha rge cycles .The battery can be cha rged and discha rged hundreds of
times, but i t will eventually wear out. Do not leave a fully cha rged ba ttery connected to a charge r since
overcharging may shorten battery lifetime . If left unused, a fully charged batte ry will lose power with time pas t.
Leaving the devi ce in hot or cold places , such as in closed ca r in summer or winter co nditions , will reduce the
capa city and life time of the ba ttery .Shoul d always try to keep the batte ry be tween 15 ℃and 25 ℃. Battery
performance is parti cularly limited in temperatures well below free zing .D o not dispose o f batteries in a fi re as
they may explode .Battery may also explode if dama ged .
Safe ty ins tru ction
Your devi ce is excellent produce in design and craft, should be used with caution. The following suggestions
will help you effectively use warranty service.
