Adjust radio volumes and/or squelch controls if squealing or unwanted feedback is experienced. Many times this condition can be eliminated simply by relocating various pieces of equipment in relation to each other.  

When used without intercom you will not hear your own voice during transmissions unless your radio is equipped with a side-tone feature. Most hand-held portable radios are not so equipped.
