Caution

If the speaker detects a problem while charging the battery, the CHARGE indicator may turn off, although 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.
• Charge the speaker in an ambient temperature of between 5 °C and 35 °C (41 °F and 95 °F).
• The speaker becomes warm during charging. This is not a malfunction.
• 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.
