The speaker and the transmitter in the Audikast 4860 set are "factory locked." This means that they should automatically connect with each other right out of the box (with both devices turned on, of course.)

If they fail to connect, please try to click button on once. If still cannot reconnect, please follow the steps below to RECONNECT and LOCK them again.

1. Get the Avantree Audikast Plus transmitter into Pairing Mode

• Connect Audikast Plus to a power source and turn it on.

• Press & Hold button  until you see the Bluetooth indicator flashing RED & BLUE.
  

2. Get the Speaker into Pairing Mode.

• Turn on the speaker - Clockwise rotate volume control to ON, the LCD screen will light up..

• Press & Hold the Bluetooth button  2 seconds. On the LED screen, it shows “Bluetooth mode，pairing”
  

3.  Wait for them to Connect. Once connected, Bluetooth icon  on the transmitter close   to and LL turn solid BLUE; Speaker LCD screen display “Connected” or “Music Playing”. 

4.  Lock them up again - Press & hold the button on the transmitter for about 10 seconds until the   indicator PINK for a couple seconds. Then the transmitter and the speaker are LOCKED and always link to each other once turned on.

The speaker coming with Audikast 4860 can be used as a wired speaker. All you have to do is plug your audio source (such as your phone or music player) into the 3.5mm AUX IN port on Speaker and play away!

Here are a few typical set ups for your reference:

Reference Connection 1  Use the AVR's Phones Output

AV Receiver Headphone port <- 6.35mm-3.5mm adapter + 3.5mm/AUX cable -> [Avantree Transmitter] AUX in from TV port ...... Headphones 

Pros: 

1. Easy to set up

2. No need to adjust the TV's audio format

3. Listen to all audio through the AV receiver / Sound bar, not just the TV program

Cons: 

Mutes the AVR speakers

Reference Connection 2 Use Optical Cable to connect the TV and AVR (Passthrough Function of Avantree Transmitter)

TV optical / digital out <- optical cable -> [Avantree Transmitter] Optical in from TV (Black) | Optical out to speaker port (Gray) <- optical cable -> Soundbar / AV receiver optical in 

Pros: 

1. Both the speakers and wireless headphones will have sound

2. Supports audio from all TV programs

Cons: 

1. Not all Avantree transmitters can do this; the ones that have this feature so far: Oasis Plus , HT5009, HT5006, Orbit , Opera , Medley Clear, Duet, & Quartet

2. Need to set the Audio format on the TV to PCM except when using with the Orbit. As a result, you can't get surround sound through the AVR speaker.

Reference Connection 3 Find an audio output on the AVR which can work with your soundbar at the same time such as the Zone 2 RCA output port (analog audio out) or the Zone 2 HDMI output (digital audio out).
In order to ensure that the Zone 2 port works, please check the manual of the AVR for how to set up Zone 2 first.




For RCA output port(Analog audio out port), please make sure its output power fits our transmitters' AUX input requirements:

1. Max input level: 2000 Vrms 

2. Input impedance < 64Ω

If you're not sure, please check with your AVR's manufacturer, or you can try to plug a pair of wired headphones into the RCA port. If you can get sound through the wired headphones as normal, then the RCA port will work with our transmitter. 

For Zone 2 HDMI output (digital audio out), you will need an additional HDMI converter to connect with the Zone 2 HDMI port.  https://avantree.com/hdmi-audio-extractor-converter-hax04

Pros: 

Keep Surround Sound 7.1 / 5.1 to your speakers with the Avantree Transmitter and TV headphones working at the same time 

Cons: 

May need to get an extra HDMI Audio Extractor 

Not every AVR has these ports in the back

If none of the above reference designs work for you, or you have other suggestions, we love to hear from you. Please email to support@avantree.com

o   Check Your TV setting again (Samsung TV, LG TV, Sony TV, Vizio TV…)

o   For AUX / RCA connections

•  Use your headphone with a wire to listen. If no sound, then no signal coming from that port

•  Transmitter base is set to AUX

o   For Optical connection,

•  Transmitter base is set to OPT

•  Make sure your TV HDMI ARC port is not connected

•  Unplug and Plug the optical cable from transmitter

•  Start your Netflix / Amazon Prime Program first before change to PCM

•  Contact your TV manufactory and ask “How to change the TV setting so i can get audio signal out of my port?”

Hearing audio through the TV speaker AND the headphones at the same time

If you'd like to get sound on both your TV speakers AND headphones at the same time, it DEPENDS on whether the TV is able to support getting sound out to two sources simultaneously. It is NOT related to the transmitter. The transmitter receieves the sound from your TV's output and streams it over to your Bluetooth headphones or speakers.

However, if you connect the transmitter to your TV via OPTICAL port and you can see the following options under the SOUND OUTPUT settings on your TV...

You can actually get sound simultaneously! Follow these steps:

1. Go to SOUND OUTPUT and change this to OPTICAL / EXTERNAL SPEAKER
2. Once there's sound going out into the headphones, go back to SOUND OUTPUT and change this back to TV SPEAKER

If your TV doesn't support simultaneous output to both the TV speakers and headphones, here are some alternative methods you can consider:

For Audio Transmitter Users:

Solution 1: Connect the Transmitter to a TV box / AV Receiver instead

If you have a TV box (DirecTV, Xfinity, Bluray Player, etc.), you should be able to find audio output ports on the back of them. Try to connect the Avantree transmitter directly here instead of the TV. This method essentially allows you to "go around" the TV's built-in speakers.

Con: will not work on streaming apps if you have a Smart TV or streaming device

For all users:

Solution 2: For users with TV Sondbar / AV Receiver

2.1 Use Transmitters with Passthrough Function

If you have a Soundbar or Stereo Receiver, check your transmitter to see if it supports passthrough. If not, you can return your current product and consider purchasing one of these: Orbit, Oasis Plus, Opera, Medley 6018, HT5009, HT5006, Duet, or Quartet.

Our industry leading "Passthrough" function allows you to put the transmitter/base between a TV and an external speaker and have audio come out from both devices AT THE SAME TIME.

2.2 Use Audio splitter/extractor

• For AUX Output - Use an audio splitter (e.g. Avantree TR302) to share the TV's audio between an EXTERNAL SPEAKER and the Transmitter. The splitter in this example is a 3.5mm audio splitter

• For Optical AUDIO OUT - Use an optical splitter (e.g. J-Tech splitter) to share the TV's audio between an EXTERNAL SPEAKER and the Transmitter. The splitter in this example is an optical audio splitter.

• For HDMI ARC OUT - Use an HDMI Audio Extractor (e.g. HAX05) to share the TV's audio between an EXTERNAL SPEAKER and the Transmitter. The splitter in this example is an ARC supported HDMI audio extractor.

When connecting 2 pairs of True Wireless (TWS) earbuds to 1 transmitter, some people are reporting frequent disconnects and the audio cutting in and out. Why is this happening? 

In general, the dual linking of 2 TWS earbuds with 1 transmitter has some interoperability issues - as far as we know ALL transmitters on the market are facing the same difficulties.

Bandwidth issues: in both of the TWS connections - one earbud (L/R) from each TWS needs to maintain a 'dual link' connection - one link to its L/R partner and one link to the transmitter. In addition, the transmitter itself must maintain a 'dual link' connection - one link for each TWS pair. In effect, there are 3 active 'dual link' connections taking place and in this scenario, due to bandwidth limitations there is often data packet loss leading to unstable connections.

Incompatibility issues: from Apple's W1 chip to Qualcomm's many offerings, there are currently dozens of different chipset solutions on the market. Although all operate under the Bluetooth standard, variances in design often leads to incompatibilities and connection issues. Another case in point, if you Google "TWS multipoint" - you will find that most TWS earbuds also have multipoint issues and cannot maintain active connections to 2 devices simultaneously.

Bluetooth and Wi-Fi devices use the same radio frequencies to communicate, so, they often interfere with one another and are prone to interference from other devices operating on the same frequencies.

Please try this simple fix:

1. Switch off the internet.

2. Turn on the Avantree transmitter and headphones and leave for 15 mins.

3. Turn on wifi router which will detect frequency used by Avantree and automatically select a different frequency.

If it does not work, there are other things you can do if you are experiencing interference on your Bluetooth or WiFi devices. These include:

1. Moving your WiFi base station to an area in the house where there is less structural interference. There are now apps available online that will scan your wireless space for you, tell you the best place to set up your base station, and even suggest the best frequency to operate on.

2. Resetting your transmitter. When you do this, it will automatically look for and default to the channel with the least amount of traffic and interference.

3. Reducing the number of wireless devices operating on the network. In an office, this could be done by relocating some employees to a separate WiFi network within the building, while at home it could be achieved by regulating family WiFi usage or plugging some devices directly into the router via cables.

Your pacemaker is designed to work properly around most appliances and tools. However, electromagnetic interference (EMI) from headphones and earbuds may affect how your pacemaker works. These effects are usually temporary. Still, we recommend following these guidelines to stay safe.

Anything that transmits Bluetooth or with a magnet inside cannot be used closer than 6'' (15 cm) to a pacemaker. All of our Headphones, Speakers, and Earbuds, as well as all of our Bluetooth products fall under this category, and must not be placed very close to your pacemaker. Normal usage of our headphones and earbuds - wearing them in or over your ears - is completely safe.

The Takeaway: It’s safe to use headphones and earbuds with your pacemaker, but you should not drape them around your neck or store them in a breast or other shirt pocket - as that would put them too close to your pacemaker. Normal usage should bear no problems.

As you may know, earbuds get dirty pretty easily... Earwax, dust, water etc. can all do damage to them. Uncleaned earbuds may lead to...

• Music sounding muddy or muffled
• Different volume on the two earbuds
• Abnormaly low volume / tinny sound after using for a period of time

Daily maintaince can effectively eliminate such problems.

• Before wearing the earbuds, make sure to clean the inner side of the ear.
• Always wear and use earbuds in dry condition.
• After using the earbuds, wipe the inside of the earbud tip with a soft and dry towel to remove dust, earwax, or oil from your skin.

If you're already experiencing different volume levels between the two earbuds, please try to follow the following steps to clean them out:

(These apply to all Avantree earbuds, but the following uses the NB18 as an example.)

1. Materials you'll need: a cotton swab and dried brush (if you can't find the black cleaning brush, a toothbrush can work instead.)

2. Take off the earbud tips from the earbuds smoothly. Do not detach the earbud tip from the earbud excessively as it may tear.

3. Use a cotton swab and dried brush to remove any debris and foreign materials.

4. If foreign substance is still present, try brushing the earbuds again to dislodge the remainder.

5. After you finish cleaning, please assemble the earbud tip back to the earbud properly. Cover the latch at the bottom of the earbud with the earbud tip like below.

Please note: Do not use liquid like alcohol or soapy water for cleaning earbuds as some of our earbuds are not alcohol-proof or soapy-waterproof.

If the problem still exists after cleaning the earbuds, please contact support@avantree.com for help.
