INSTRUCTIONS
BATTERY CARE GUIDE
Your speaker comes equipped with a high-performance lithium-ion battery
and the life span is aected by charging and usage. Follow the guidelines
below to keep your battery in great condition for as long as possible.
• Avoid using fast chargers if possible. Fast charging
causes stress on the battery and will degrade it.
• Avoid charging the battery when it is already full or letting it drain
completely. Try keeping the charge between 30% and 80%.
• If the speaker is stored for a long time, do so with a half-
charged battery and in a cool, dark, and dry place.
• Do not use or charge the speaker in hot and unventilated places, 45°C/113°F
and above, such as in a parked car or by a window in direct sunlight.
• Avoid charging the battery at low temperatures, below
10°C/50°F and using the speaker below 0°C/32°F.
• Avoid strong mechanical shocks such as dropping the speaker
on hard surfaces as it might damage the battery.
PERFORMING A FACTORY RESET
A factory reset will return the speaker to its original
settings, excluding any firmware updates.
Note: This will delete all user settings meaning the speaker will need to be
set up again.
I. Ensure that the speaker is on.
II. Push and hold the Bluetooth button for 7 seconds. All indicators turn
o and the speaker restarts.
III. Remove Middleton from your audio device’s Bluetooth list before
pairing again.
MARSHALL BLUETOOTH APP
Download the Marshall Bluetooth app to get the most out of your
speaker and keep it up to date with the latest software.
