The wireless charge receiver in the smartphone may not be adequately coupled to the wireless charging transmitter on Smartbase. Re-adjust your smart phone’s position on the wireless charge arm.

The rechargeable AAA cells may of course be worn out, or they may not be installed at all. If this is the case, either insert the cells, or you can order new cells as original spare parts. Please contact Harman Helpdesk for your country, or the distributor for your country, for further info about how to buy new cells. Please note that the cells MUST be compatible with charging contact for the minus pole located on the side of the cell. Normal cells will not work. This is clearly mentioned in the owner's manual, and shown with a drawing. If you have purchased new cells with plastic coating along the length of the cell, it may be possible to peel off the coating by cutting gently with a knife, then peeling it off. Only about 1 cm needs to be open to the metal, closest to the flat end, for contact to be possible. Please note that the ear pads on K 912 are removed by simply grabbing the plastic plate that holds the ear pad, and pulling it away from the ear pod. There is one battery in each ear pod. For K 915, never just pull the pad away, since the locking claws are released by being rotated away from their locked position.. Both batteries are under the right-hand pad, and there is a silk-screened instruction on the top of the pod, showing that you must rotate the pad plate just a few mm counter-clockwise to unlock it.

The PartyBoost feature is not available when your JBL speaker is connected to a computer via Bluetooth. This is a technical limitation. When connected to a computer, the computer is acting as the primary device. Therefore, the JBL speaker does not have control of re-transmitting the Bluetooth signal to other JBL speakers.

NOTE: Speakers effected by this are the JBL Flip 5, JBL Flip 6, JBL Charge 5, JBL Pulse 4, JBL Xtreme 3, and JBL Boombox 2, as well as future products featuring the PartyBoost feature.

• Please check whether your head unit Bluetooth support EDR (Enhanced Data Rate) • If the head unit does not support EDR this will cause the transfer data rate to be low and will impact the audio quality.

This problem is usually caused by pressing down too hard on the soundbar's VOL + or VOL - Buttons. Only press just enough for one click to be felt. If a second click is felt in the button, you are pressing too hard, and you are actually activating the MUTE function for learning, not VOL up or down. You may have to repeatedly let go of the VOL button on the soundbar, followed by pressing it again and then pressing the VOL button on the TV remote before the surround light on the soundbar lights up white and goes back to amber flashing, as a sign that this function has been learned. This is no problem, though. Just keep trying until the three commands have been learned. The soundbar only exits learning mode when you press and hold the surround button as the final step.

Please note that the LFE Trim function is only active with surround source signals that feature a separate LFE track for the subwoofer. It does not affect subwoofer level when playing stereo or mono.

When the speaker is switching quickly between music sources via Bluetooth, it's normal to experience a very short 'pop' sound because the Bluetooth signal is breaking in and doing the handshake with the speaker. It won't appear after the Bluetooth signal is stable.

Yes, when changing volume to higher or lower, the LED will illuminate to show that you are changing the volume.

First try using a different flash drive, we recommend the following: ScanDisk PNY Kingston Verbatim If the problem persists try using an updated version of Winzip when downloading the zip file to the USB flash drive.

The Normal and Pulsed DC triggers are active (on) when the No. 523 and No. 526 is on, they are not active (off) when the No. 523 and No. 526 is off. The Theatre DC trigger is present only if the current input is in SSP mode, otherwise this trigger is off.

JBL QuantumSPHERE 360 is JBL QuantumSURROUND that’s kicked up a notch by using a head-tracking sensor to fix sounds in 360 degrees of space around you. With typical headphones, when you move your head, the soundscape follows your movement. But with JBL QuantumSPHERE 360, if you rotate your head, the sound source’s perceived location stays in place because the head-tracking sensor compensates for your head movement. For example, if there’s a sound coming from in front of you, and you turn your head to the left, the sound source’s perceived location moves to your right ear—the sound stays locked in space as you move your head. 

Also, the human brain uses small head movements to distinguish if sound sources are behind or in front of us. The brain processes the differences between when a sound arrives at the left vs. the right ear to determine where the sound is located. So with JBL QuantumSPHERE 360, you can move your head naturally to pinpoint the exact source of sounds around you. 

LE Audio is the next generation of Bluetooth Audio, making audio streaming over Bluetooth Low Energy possible. It enables new use cases and significantly reduces power consumption compared to Classic (BR/EDR) Audio. LE Audio allows for independently synchronized audio streams to each earbud as well as seamlessly broadcasting audio streams to multiple listeners, with low power consumption.

You can now install your JBL LINK speaker to your Wireless Network and you can find our setup article that shows how to install your LINK product.

 

10 minutes before the time limit has been reached, a voice prompt will be played on the headphones. When reaching the time limit, the volume will be muted, and a new voice prompt will inform that the listening limit has been reached.

Citation speakers support 802.11g, 802.11n, and 802.11ac standards on both 2.4 GHz and 5 GHz bands. We recommend using 5 GHz if available, as this will give you more stable performance and use the full power of your wireless audio. Contact our customer support to get in touch with an expert that can help you with your Wi-Fi network. We are here to help!

Normal: Trigger output is a standard 12VDC signal. Pulsed: Trigger output in a 12V pulse 50-100ms wide. Theatre: Turns the trigger on (standard 12VDC) only if the current input is in SSP mode, otherwise the trigger is off.

The connector between headphones and cable is Mini-XLR with lock mechanism. The connector that goes into sources is a combination plug, 3.5mm jack with 6.3mm adapter.

Normally, the InfinityLab power bank may be warm to the touch during discharging.  
However, if the power bank becomes too hot, starts to expand, or emits a strong odor, please stop using it immediately and contact our customer service. 

Let's run through some basic check marks to ensure we didn't miss anything while setting up your device.

1. Your Citation device is turned on
2. Check the password you have entered, and re-enter it again (typos can happen).
3. Make sure your mobile device has the initial support needed:
   1. Android 4.4 OS and higher
   2. Apple iOS 10 OS and higher
   3. The latest version of Google Home app
4. Your phone needs Bluetooth to be on 
5. Enable Location Service (Android only)
6. Plus you need to permit Google Home app to access your location on the phone (Android only).

The basic check is done, and we are now moving into your Wireless network setup.

1. Try moving your speaker closer to the Wireless network router 
2. Have you previously connected the speaker to your WiFi network?  If yes, look below or move to "Troubleshooting"
   1. Did you recently make any changes to your network, such as buying a new router, adding an extender, or maybe changed settings?

   2. Maybe your ISP (Internet Service Provider) did some changes, possibly even updating your Wireless router software.

If you still are experiencing issues connecting the device to your Wireless network, let's do some further troubleshooting.

Troubleshooting

1. Your WiFi router might need a reboot, unplug power for 1 minute and connect power again.
   1. While you are rebooting your WiFi router, we advise doing the same for your speaker. Simply disconnect power and reconnect power again.
   2. In case rebooting the speaker didn't work, let's try resetting your speaker by pressing the Reset Button for 5 seconds (Front LED will light up).
2. Go ahead with the setup again (remember to open Google Home app )
3. Reboot your mobile device

WiFi Network Troubleshooting

• Check your WiFi router settings. Be sure that UPnP (Universal Plug and Play) is enabled.
• Change Wireless channels on your WiFi router on 2.4G or 5G..
  • Avoid using other channels on 2.4G other than 1, 6 and 11. The rest are a NO-GO.
  • Keep a maximum of 8 devices in total on 2.4G (that is including our speakers).
  • Move products to WiFi 5G band, if they support it, to reduce the stress factor on the 2.4G band
• Check your WiFi router to see if there is a MAC address limitation.
  • MAC address limitation is when your router is set/fixed to a maximum of 20 devices (or whatever it may have been configured for).
  • When you want to add the 21st device your router will deny access because you have filled up the 20 devices.
  • You need to clear or delete old devices that are not in use anymore. This may require someone with technical knowledge.
  • We advise that you don't have any MAC address limitations at all.
• Avoid bad extenders (Cheap ones are often not powerful enough to deal with or handle the kind of data required to transmit high quality audio).
  • With extenders, the connection between "router and extender" is decreased by 50%.  That said, your data will be even slower,. having to processes it while the speed is decreased.

There are more things you can do to optimize your WiFi router, but these above are the most common issues happening in users homes.

 

Make sure both headphones are fully charged to ensure that the issue is not due to one of the earbuds lacking power.

Check that the contact points on the headphones and the charging case are clear of dirt, so the issue is not due to the product not being able to charge.

The LED on the headphones will show a blue light when correctly inserted in the charging case.

Try to reset the headphones if the product is fully charged but are still only working in Mono mode.

A reset guide for the headphones can be found here: Reset guide

To have the best Active Noise Canceling performance possible, we advise you to keep the earbuds clean as much as possible. In case the IR sensors are covered with dirt of any kind, the Active Noise Cancellation performance will not be as effective. Sometimes, it may not give you the desire outcome to enjoy your music. 

If your teammates can not hear you, make sure of the following:

USB is correctly plugged in
Only one voice chat application is in use while in-game.
The mic input is set to JBL Quantum Stream.
Mic gain is not turned all the way down
Mic is not muted (mute/unmute by pressing the touch panel on top of the mic). By default the RBG will indicate red for muted, and green for unmuted(active).

 

If you are not able to turn Spatial Audio on and the option is greyed out on the JBL Smart Tx, then you need to do the following.

• Open the JBL Headphones app
• Disable High-Resolution Audio (LDAC)
• The headphones will turn off and reboot
• You can enable Spatial Audio after the reboot

Make sure to check that the USB-C connector on the phone is clean and free of dirt and dust. A dirty connection could result in a disconnection during physical activities such as walking or running. A clean USB-C connection is needed in order to establish a good sound connection.

The first thing you’ll notice is that sound no longer feels like it’s “inside your head.” Suddenly it seems like the game audio is coming from high-quality loudspeakers—or the virtual game world—all around you.

It’s a different experience than you get with other headphones, and may take a little while to adjust to. For example, sounds coming from sources in the distance will seem farther away, as they would in real life. Even though you might be used to those sounds feeling closer with other headphones, JBL QuantumSURROUND provides hyper-accurate spatialization that can give you a competitive edge.

So spend some time dialing in the EQ to your liking, and see how real-world hearing helps you pinpoint enemies and bring the game to life. 
 

If you are having trouble with distortion or drop outs, try the following suggestions: 1. Move the audio source closer to the speakers. 2. Move the speakers closer to each other. 3. Make sure only one of the two speakers are connected to the audio source. If both are connected to the audio source, disconnect the connection between the audio source and the second speaker. 4. Make sure the audio source connects with one streaming speaker only, disconnect other Bluetooth connection. 5. Restart both your speakers and the audio source. 6. Make sure the environment is not congested by other wireless signals.

Different games have different settings, but as a general rule, make sure that your game outputs multi-channel unprocessed audio. We recommend 7.1 surround, but 5.1 works too. Always disable any other processing (like DTS and Dolby).  

To have the best possible performance for OMNI+ system we advise to have a dual-band router with a powerful chipset and ram for best Wi-Fi performance. This will not only help our products to perform better and more stable, but your other devices at home will have more power and fewer interruptions. Please also be sure that your home Wi-Fi router has Multicast enabled, as our Omni+ system requires this feature enabled in order to work (same goes for Chromecast devices). Always connect our Omni+ system to 5 GHz Wi-Fi whenever possible to limit the risk of devices being slow or interrupted on 2.4GHz Wi-Fi.

The Harman Kardon Wireless HD Audio System uses UDP ports 6060 and 6080.

The JBL Quantum TWS an JBL Quantum TWS Air supports two types of wireless connection at the same time. It's compatible with any Bluetooth compatible devices while the USB wireless dongle enables compatibility with PC/Mac, PS4/5, Nintendo Switch^TM, TV and iPads and Android^TM devices with USB-Connection (Note: Type-C supports PS5 while type-A is compatible with all PlayStation^TM model).
