How to use

Insert fresh AA batteries into the battery compartment following the polarity markings and secure the battery cover. Attach a compatible lavalier or headset microphone to the transmitter's mic input and clip the bodypack to the belt or place it in a pocket within clear line of sight of the receiver where possible.

Recommendations

For consistent performance, use high-quality AA batteries and replace them before long sessions. Maintain a clear line of sight between transmitter and receiver when possible, and perform a frequency scan to avoid local RF interference. Regularly inspect the microphone cable and connector for wear to ensure reliable audio transmission.
