How do I reset the Charge 4?In order to reset the Charge 4, with the unit on, press “Volume+” and “Bluetooth” at the same time for 3-4 seconds until you hear the audible chime.
How to avoid Bluetooth Interference or Interruptions• Always have clear line of sight between your Bluetooth device (speaker, headphones etc.) and source device (Smartphone/tablet/PC etc). Be aware of obstacles in front of your devices.
• Try to shutdown other products that have Bluetooth, but are not being used. They are often the reason for interference even though they are not being used.
• Do not stand too close to your Wi-Fi router since a Wi-Fi signal is stronger and in many cases will "overlap" the connection.
• Be aware of walls around you. Concrete and brick walls will often interrupt the signal, as it cannot pass through such thick walls.
• Bluetooth signals cannot travel through water, which includes the human body. Make sure with wireless headphones to keep your source device and the receiver on the same side of your body.
• Open spaces such as parks can cause issues for your devices, as open air is "bad" for any Bluetooth signal if it cannot reflect from objects around you.

Pairing issues with a Computer or PCIn most cases when a Computer/PC/Laptop has issues connecting to a Bluetooth device (Portable speaker, Headphones, Active speakers), it's caused by your Computer/PC/Laptop's Bluetooth driver (software).
The driver (software) should support the following Bluetooth protocols, to be able to play music/sound from your Computer/PC/Laptop:
• A2DP (Advanced Audio Distribution Profile) driver for your Computer/PC/Headphones to transfer music.
• AVRCP (Audio/Video Remote Control Profile) driver to send skip/forward/pause/play music to your device
Always get the latest driver version available for your Computer/PC/Laptop.
To download the correct driver (software), visit the manufacturer's website of your Computer/PC/Laptop. They usually have a "Support/Download" section where you can find the correct driver. Otherwise, we advise you to contact their support.
The standard drivers provided by Microsoft/Windows system are not correct and will result in error messages (such as having to enter a PIN code), or pairing will not work.
PartyBoost support on the JBL Connect and JBL Connect+
The new PartyBoost does not support the previous Connect and Connect+ features. For example: You will not be able to successfully connect the new PartyBoost enabled Flip 5 with a Connect+ enabled speaker like the Pulse 3 or Flip 4. You will not be able to connect the Boombox 2 to the original Boombox speaker.

To put it in pairing mode, hold down the Bluetooth button for at least 3 seconds, until the light flashes blue. You are now in pairing mode. Locate the Charge 4 on your device, select and you should connect successfully within a few seconds in which you will hear the audible chime.
Issues with the JBL Portable App and your Android device
There might be several reasons that our Portable app may not be working correctly on your Android device. First, your Android device must have 5.0 OS (Operating system) or higher to support JBL Connect app. Devices under 5.0 OS will not be supported. If you are having trouble viewing your JBL Portable device in the app, please disable Bluetooth, and then turn it back on again. Now you should be able to see your device in the JBL Portable app.
What are the differences between Partyboost and Connect+Our newest products, such has JBL Pulse 4 and JBL Flip 5, feature a new technology called Partyboost .
- Improved Bluetooth connection between speakers.
- A more powerful Bluetooth transmitter means that the speakers can be farther apart.
- Partyboost can only connect to other Partyboost speakers.
Unfortunately, this feature is not backwards compatible with previous models that have JBL Connect or Connect+.
