## Long description

How to use
Fit the SL Headmic 1 on the head so the microphone capsule is positioned near the mouth but out of the direct airflow. Connect the headmic to the SL Bodypack DW transmitter and switch on both transmitter and SL Rack Receiver DW. Ensure the receiver and transmitter are set to matching frequencies; the system supports automatic frequency and interference management to simplify synchronization. Insert the BA 30 rechargeable accu pack into the transmitter and monitor battery status during use. For rack installations, use the supplied GA 4 rackmount kit; for mobile use, store components in the supplied transport case if included.
Usage recommendations
For optimal speech clarity, position the microphone within 2–3 cm from the corner of the mouth and avoid direct breath on the capsule. Use the automatic frequency management feature to scan for the clearest channel before each performance. Charge the BA 30 battery fully before extended use and keep the USB charging cable accessible for quick recharging between sessions.
