Top Tips
1. If feedback (screeching or howling) occurs, lower the volume setting and move the microphone away from the headset or earphones, also try turning the tone control down (or counterclockwise) to reduce high frequencies.
2. Please hold or place the PSAP about 4 inches toward to the target sound for daily conversations, and avoid rubbing against any surface.
3.This is a personal amplifier that amplifies all sounds proportionally, so it is not recommended for use in noisy environments( such as a driver's cab).
4. Joanbro amplifiers offer 3 types of MIC for a tailored listening experience. In particular, the MIC3- suction cup microphone, equipped with a 6-meter cable and nylon fasteners, is perfect for remote TV watching.
5. First turn down the volume, then put on headphones or earphones and adjust the volume to a comfortable level.
