Using the Hollyland LARK 150 Duo is a breeze. First, take the transmitter and receiver out of the charging case. They'll pair automatically, so you can start using them right away. Clip the transmitter to your collar or attach it using the belt clip.
When connecting to your shooting equipment, if you're using a mobile device, you'll need an adapter cable from Hollyland. For other devices like cameras or computers, simply use the 3.5mm cables provided.
During use, keep an eye on the power indicators. Red means low battery, green means safe, and orange means charging. If you're doing physical activities, the noise buffer design will help keep the audio clean, but try to avoid rough movements that could still cause some noise.
When it's time to charge, use the Type - C port on the charging case. It takes about 45 minutes to charge the transmitter, 65 minutes for the receiver, and 2.5 hours for the charging case. The charging case can charge 2 transmitters and 1 receiver about 2.5 times when fully charged.
To keep your microphone in good condition, clean it gently with a soft cloth. Don't expose it to extreme temperatures or moisture. And if you need to update the firmware, you can do it through a PC.
