ENGLISHINSTRUCTIONS
CLEANING THE SPEAKER
Clean your speaker regularly to keep it fresh and last longer.
Unplug any leads before cleaning the speaker and make sure everything is
completely dry before plugging in a USB charger.
Remove the carry strap from the speaker and clean it with a soft brush.
Gently clean the speaker and the leads with a lint-free cloth, slightly damp
with either:
• water,
• 70% isopropyl alcohol, or
• 75% ethyl alcohol
Carefully clean the openings with a dry and soft brush, or a cotton swab.
• Do not use any sharp or metal objects.
• Do not use compressed air.
• Do not use products containing bleach or hydrogen peroxide.
• Do not submerge the speaker in any cleaning agents.
• Do not rinse the speaker under running water.
BATTERY CARE GUIDE
Your speaker comes equipped with high-performance lithium-ion batteries
with a life span that is aected by charging and usage. Follow the guidelines
below to keep your battery in great condition for as long possible.
• Avoid using fast chargers if possible. Fast charging causes stress on the
battery and will degrade it.
• Avoid letting the battery drain completely or charging it when it’s already
full. Try to keep the charge between 30% and 80%.
• If the speaker is stored for a long time, it is recommended to charge
the speaker to about half-charge and then do a factory reset. Store the
speaker in a cool, dark, and dry place.
• Avoid using or charging the speaker in hot and unventilated places,
40°C/104°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 harm the batteries.
Download the Marshall Bluetooth app and select the battery preservation
level that best suits you and your speaker.
