Mobile Version Installation and Connection Guide

1. Preferred Placement for TX: Attach it to your collar. If you speak loudly, place it higher up on your chest. Use either a clip or magnet for attachment.

1. Place the magnet on the inside of your collar and attach the TX to the magnet on the outer side.
   

* If the volume of the recorded voice is fluctuating, it's probably because the microphone isn't placed properly. So, make sure that the microphone is unobstructed. If you're recording outside, use a windscreen to minimize wind and breath noise.
