How to use it as a Bluetooth transmitter

BTI-020V and stereo Bluetooth headphone or Bluetooth speaker (A2DP enabled) work on the TV

A, Make the Bluetooth speaker or Bluetooth headset in pairing mode.

B. Press MFB around 3 seconds until Blue LED flashes quickly to enter into searing mode, if BTI-020V does not

enter into pairing mode, press MFB 2 Seconds then double press MFB ( keep the operation consistently ) to enter
into pairing mode.

C. Put the BTI-020V and Bluetooth speaker or Bluetooth headset together, around 30s seconds later, BTI-020V

will connect with Bluetooth speaker or Bluetooth headset automatically

D. Connect the BTI-020V and TV with 3.5mm audio cable. (Plug one side of the audio cable to the audio output
jack of the TV, the side to BTI-020V)

E. It could hear the sound coming from TV in the Bluetooth headset or Bluetooth speaker. If no sound in the

Bluetooth speaker or Bluetooth headset, please check the aux output setting on TV is by the headset output, the

volume of the TV is loud enough, the cable connects right or not. Use your finger to touch the DC part of the

audio cable that connected with BTI-020V to check if the audio source has problems. When the connection is

successful and the volume of headset or speaker is big enough, you will hear a

“

zi,zi

”

sound, it means BTI-020V

and Bluetooth speaker or Bluetooth headphone and cables are ok, the problem may be on the audio source
(TV

）

BTI-020V and Bluetooth headset or Bluetooth speaker which must support A2DP work together on the
computer.

A. Make the Bluetooth speaker or Bluetooth headset in pairing mode.

B. Press MFB around 3 seconds until Blue LED flashes quickly to enter into pairing mode, if BTI-020V does

not enter into pairing mode, press MFB 2 Seconds then double press MFB ( keep the action consistently )) to
enter into pairing mode.

C. Put the BTI-020V and Bluetooth speaker or Bluetooth headphone together, around30 seconds later, BTI-

020V will connect with Bluetooth speaker or Bluetooth headphone automatically.

D. Connect the BTI-020V and computer with 3.5mm audio cable.

E. It could hear the sound coming from computer in the Bluetooth headset or Bluetooth speaker. If no sound

in the Bluetooth speaker or Bluetooth headset, please check the aux output setting on computer is by the

headset output, the volume of the computer is loud enough, the cable connects right or not. Use your hands to

touch the plug of the audio cable for BTI-020V to check if the audio source has problems. When the connection is

successful and the volume of headset or speaker is big enough, you will hear a

“

zi,zi

”

sound, it means BTI-020V

and Bluetooth speaker or Bluetooth headphone and cables are ok, the problem may be on the computer.

Note: Passcode for supported Bluetooth headset, Bluetooth receiver, Bluetooth speaker etc.
is ”0000”,”1234”,”1111”,”8888”

BTI-020V and Bluetooth headset or Bluetooth speaker that supported A2DP worked on other audio device

which supports headset profile). BTI-020V and Bluetooth headset or Bluetooth speaker could replace a

wired earphone from wired connection to wireless connection, remove the wire limited, bring more fun for
you.



BTI-020V connect with two device simultaneously while working as a Bluetooth transmitter

This unit could connect with two stereo Bluetooth speaker or Bluetooth headset to play music
simultaneously

A. Named the two Bluetooth headsets or two Bluetooth speakers as A and B.

B. Select the TR mode for the device BTI-020V

C. Follow the above pairing steps in working as a Bluetooth transmitter to connect device A and BTI-020V

D. When the connection is successful, power off the device A, and pairing the Device B with BTI-020V

(following the same paring steps )

E. After successfully connecting with device B, then power off BTI-020V.

F. Power on the device A (do not enter into pairing mode, but if it enters into pairing mode, it

’

s ok), around

10-20 seconds later (in this case, most of the Bluetooth speaker is for automatically connection, please wait a
moment)

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 pairing time will take around 30 seconds. Then connect to audio resource to check

if the two devices could play simultaneously. If not, please power off BTI-020V, and reopen BTI-020V to
connect with device A and B.

If reopen BTI-020V does not work, please rework the steps for two connections simultaneously.

The compatibility testing report for BTI-020V worked as Bluetooth transmitter to connect with two device
simultaneously

1. Due to different Bluetooth chipset has different function firmware setting and different operations so

some Bluetooth speaker or Bluetooth headset may have compatible problems with BTI-020V. When one of the

devices has no sound or discontinuous playing, please re-pair the two devices two or three times to check if
there has same situation, then we could have a result if it is wrong in compatibility

2. There so many Bluetooth speaker, Bluetooth headphone with different Bluetooth chipset on the market.

We tested the different Bluetooth chipset compatibility with BTI-020V:

Battery information

Your device is powered by a rechargeable battery .The full performance of a new battery is achieved only

after two of three complete charge and discharge cycles .The battery can be charged and discharged hundreds of

times, but it will eventually wear out. Do not leave a fully charged battery connected to a charger since

overcharging may shorten battery lifetime. If left unused, a fully charged battery will lose power with time past.

Leaving the device in hot or cold places, such as in closed car in summer or winter conditions , will reduce the
capacity and lifetime of the battery .Should always try to keep the battery between 15

℃

and 25

℃

. Battery

performance is particularly limited in temperatures well below freezing .Do not dispose of batteries in a fire as
they may explode .Battery may also explode if damaged.



Safety instruction
