Packaging list
Tips for pairing：
1. Put the Blue too th he adse t or Blue tooth s peake r into pairin g mode . Then powe r on BTI-020V will
co nnect to BTI-020V quickly again,if the Bl uetoo th heads et or Bluetooth spea ke r conne cted with BTI -020V
before. No need to make the BTI-020V ente r into pai ring mode .
2. If BTI-020V did n ot conne ct with the Blue too th he adse t or spea ke r mo re than 1 minutes. Please try
to clea r up the pairing list of the BTI-020V. I f the Blue too th headset or Blue too th speaker connected with
BTI -020V before, please reopen the BTI-020V after clear up the pai ring list.
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 discha rge cycles .The battery can be cha rged and discha rged hundreds of
times, but i t will eventuall y wear out. Do not leave a fully charged ba tte ry conne cted to a charger since
overcharging may shorten battery lifetime. If left unused, a fully charged battery 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 conditions , will reduce the
capa city and life time of the ba ttery .Shoul d always try to keep the ba tte ry betwee n 15 ℃and 25 ℃. Battery
performance is particularl y limited in temperatures well below freezing .Do not dispose o f batteries in a fire 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.

co rrode ele ctroni c circuit.
3. If the devi ce is wet, please make i t completely dry.
4. Do not use o r put the devices in dust or di rt s tora ge , it will damage the deta chable pa rts and elect ronic
components.
5. Do no t use e quip ment sto red in overhea ting, hi gh tempe ra tu re will sh orten the se rvi ce life of el ectroni c
devices, damage batteries, make some plastic parts deformation or melt.
6. Do not use equipment stored in a cold place, or when the de vi ce tempe rature to roo m tempe rature, its
internal will form the moisture, it will destroy circuit board.
7. Do not a ttempt to disassemble the equipment.
8. Do no t throw, be at or vib ra tio n equipmen t, rough treatment equipmen t can damage the in ternal
ci rcui t b oard a nd sophi sti cate d structu re.
9. Do not use s tron g chemi cals, de tergent or dete rgent to clean the de vice.
10. Do not use pigmen t daub eq uipme n t, daub will blo ck sundries in the removable compo nents a nd thus
affect the normal operation.
