Caution

If the speaker detects a problem while charging the battery, the CHARGE indicator may turn off, even though charging is not completed.

Check for the following causes:

• Ambient temperature exceeds the range of 5 °C – 35 °C (41 °F – 95 °F).
• There is a problem with the battery.

Note

• Charging time varies depending on battery usage conditions.
• The speaker becomes warm during charging. This is not a malfunction.
• If the inside of the speaker heats up after extended use in a hot environment, charging may not start. This is to protect the battery and is not a malfunction. When the inside of the speaker has cooled down, charging will start.
• If the speaker is not used for a long time, it may take longer to charge the battery.
• Avoid exposure to rapid temperature change, direct sunlight, moisture, sand, dust, or mechanical shock. Also, never leave the speaker in a car parked in the sun.
