Maintenance
1. Cleaning
Wipe the microphones, receiver, and charging case with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials, as these can damage the device. Ensure no moisture enters the ports or microphone grilles.
2. Storage
When not in use, store the system in its charging case in a cool, dry place, away from direct sunlight and extreme temperatures. This protects the components and helps maintain battery life.
3. Battery Care
To prolong battery life, avoid fully discharging the devices frequently. Recharge the system regularly, even if not in constant use. The charging case provides up to 30 hours of total usage time for the microphones, with individual microphones offering 6 hours of continuous use on a single charge.
