## Long description

BY-WM3U is a compact 2.4 GHz wireless mobile phone microphone system designed to deliver broadcast-quality audio to Android smartphones, tablets and USB-C computers, as well as DSLRs, camcorders and portable recorders. The set includes a clip-on miniature transmitter with foam and fur windshields, a compact receiver with multiple adapters, and a Type-C charging carry case with an internal rechargeable battery.
Advantages
The BY-WM3U operates on the 2.4 GHz band that can be used in any country without worrying about regional band limitations. The included Type-C charging carry case provides storage protection and a built-in 1000 mAh battery for on-the-go charging, allowing extended operation time. The receiver ships with a Type-C adapter plus 3.5 mm TRS and TRRS adapters for wide device compatibility; the transmitter’s foam and fur windshields reduce wind and environmental noise.

How to use
Charge the transmitter, receiver and the Type-C charging case before first use. Place the transmitter on the talent using the clip and fit the foam or fur windshield as needed to reduce wind noise. Connect the receiver to your device using the appropriate adapter (Type-C for compatible smartphones/tablets/computers or 3.5 mm TRS/TRRS for cameras and recorders). Use the one-touch pairing function built into the charging case to pair transmitter and receiver quickly without navigating menus. Position the receiver within the specified operating range for stable RF connection.
Usage recommendations
For best results, keep a clear line of sight between transmitter and receiver and avoid placing both units directly behind large obstructions. Fully charge the case to extend total system runtime and use the fur windshield outdoors in windy conditions; the one-touch pairing feature allows fast setup when moving between locations.
