JBL Xtreme2 Manual

If your JBL Xtreme 2 is not charging, please try the following troubleshooting steps:

• Check the Power Supply: Ensure you are using the original 19V 3A power adapter provided with the speaker. Verify that the wall outlet is functional and the cable is securely connected to both the outlet and the speaker's DC input.
• Inspect the Charging Port: Check the charging port under the waterproof cap for any debris, dust, or damage. Ensure the connection is tight.
• Reset the Speaker: Sometimes a software glitch can prevent charging. While the speaker is on, press and hold the Volume Up (+) and Play/Pause buttons simultaneously for about 5 seconds until the speaker turns off. Then try charging it again.
• Check LED Behavior: Observe the battery level LEDs. If they do not light up at all when plugged in, the battery or the internal charging circuit may be faulty.
• Battery Maintenance: Note that the manual recommends recharging the battery at least once every 3 months if not in use to maintain battery health. If the battery has been depleted for a very long time, it may fail to accept a charge.

Warning: Do not expose the JBL Xtreme 2 to water while charging, as this can cause permanent damage to the speaker or power source.

The audio cutting out when using the AUX input is often caused by the speaker's Auto-Power Off (APO) or power-saving logic. This happens when the input signal from your source device (phone, laptop, etc.) is too low, leading the speaker to believe no audio is playing.

To resolve this, try the following steps:

• Increase Source Volume: Turn the volume on your source device (the device plugged into the AUX cable) to 80-100%. Then, use the buttons on the JBL Xtreme 2 to adjust the actual listening volume. This ensures the speaker receives a strong enough signal to stay active.
• Check the Cable: Ensure the 3.5mm AUX cable is fully seated in both the speaker and the source device. A loose connection can cause signal drops.
• Firmware Update: Use the JBL Connect app on your smartphone to check for and install any available firmware updates, as these can sometimes refine power-management behavior.

Note: The manual does not list a specific button combination to disable the power-saving feature entirely, as it is a standard part of the IPX7-rated hardware design to preserve battery life.

If your new JBL Xtreme 2 is not turning on, please try the following troubleshooting steps:

• Charge the device: Connect the speaker to the provided 19V 3A power adapter. New units often arrive with a depleted battery. A full charge takes approximately 3.5 hours.
• Check the Power Source: Ensure the power outlet is working and the cable is securely connected to both the wall and the speaker's charging port.
• Reset the Speaker: If the device is unresponsive, you can attempt a reset by pressing and holding the Volume Up (+) and Play/Pause buttons simultaneously for about 5-10 seconds while the unit is powered (or plugged in).
• Check LED Behavior: Observe the battery level indicator LEDs. If no lights appear even when plugged in, there may be an issue with the power adapter or the internal battery.

Note: If the speaker still does not turn on after several hours of charging, it may be defective. Since you just received it, we recommend contacting the retailer for a replacement or JBL support for warranty service.

The JBL Xtreme 2 is designed with a speakerphone feature (HFP/HSP profiles) that automatically prioritizes incoming calls by pausing music playback. To prevent your iPhone from cutting off the sound when a call comes through, you can try the following steps on your iPhone:

• Change Audio Routing: On your iPhone, go to Settings > Accessibility > Touch > Call Audio Routing. Change the setting from "Automatic" to "Speaker" or "Bluetooth Headset" to control where the audio defaults, though this may not entirely stop the interruption.
• Use Do Not Disturb: Enable Do Not Disturb or a Focus Mode on your iPhone while listening to music. This will prevent incoming calls from ringing through and interrupting the Bluetooth stream.
• Disconnect Speakerphone Profile: While the manual does not list a way to disable the speakerphone feature directly on the device, you can sometimes go to your iPhone's Bluetooth settings, tap the "i" icon next to the JBL Xtreme 2, and see if there is a toggle to disable "Phone Calls" while leaving "Media Audio" active (note: this option varies by iOS version and device compatibility).

Please note that because the speaker is designed to function as a speakerphone, the default behavior is to pause music to allow you to take the call using the speaker's built-in microphone.

Yes, it is generally safe to leave your JBL Xtreme 2 plugged into AC power. Modern JBL speakers, including the Xtreme 2, utilize sophisticated battery management systems that prevent overcharging. Once the Lithium-ion battery reaches a full charge, the device will prioritize drawing power directly from the AC adapter rather than continuously cycling the battery.

However, to maintain the long-term health of the battery, please keep the following in mind:

• Periodic Discharge: While the unit won't "overcharge," Lithium-ion batteries benefit from being exercised. It is recommended to unplug the speaker and let the battery drain partially or fully at least once every few weeks to keep the battery chemistry active.
• Storage Maintenance: As noted in the manual, if you plan to leave the speaker unused for a long period, you should still recharge the battery at least once every 3 months to prevent it from falling into a deep discharge state.
• Performance Benefit: Using the speaker on AC power is actually beneficial for performance; the Xtreme 2 provides its full rated power (2 x 20W RMS) in AC mode, whereas output may be slightly limited when running on battery alone to conserve energy.

When you plug in your JBL Xtreme 2, the battery level indicator (the row of LEDs at the bottom) should blink to indicate it is charging. If no lights appear, please check the following:

• Check the Power Supply: Ensure you are using the original 19V 3A power adapter. The Xtreme 2 requires a specific voltage that standard USB chargers cannot provide.
• Verify the Connection: Ensure the power cord is firmly seated in both the wall outlet and the charging port behind the waterproof cap on the speaker.
• LED Behavior: Under normal operation, the LEDs will flash one by one as the battery charges. If the battery is completely depleted, it may take several minutes of charging before the LEDs begin to show activity.

If the speaker still does not light up after 30 minutes of charging, there may be an issue with the power adapter or the internal battery. Note that the manual recommends recharging the battery at least once every 3 months to maintain battery health.
