- Gently clean the speaker and leads with a lint-free cloth, slightly damp with water, 70% isopropyl alcohol, or 75% ethyl alcohol.
- Carefully clean the speaker mesh and openings with a dry, soft brush or a cotton swab.
- Do NOT use sharp or metal objects, compressed air, products containing bleach or hydrogen peroxide, or submerge the speaker in cleaning agents. Do not rinse under running water.
Battery Care Guide
Your speaker uses high-performance lithium-ion batteries. Follow these guidelines for optimal battery life:
- Avoid using fast chargers if possible, as they can degrade battery health.
- Do not let the battery drain completely or overcharge it. Aim to keep the charge between 30% and 80%.
- If storing the speaker for a long time, charge it to about half-capacity, perform a factory reset, and store it in a cool, dark, dry place.
- Avoid using or charging the speaker in hot environments (above 45°C/113°F) or direct sunlight.
- Avoid charging the battery at low temperatures (below 10°C/50°F) and using the speaker below 0°C/32°F.
- Protect the speaker from strong mechanical shocks, such as dropping it on hard surfaces.
For advanced battery management, download the Marshall Bluetooth app to select a battery preservation level.
