When you turn on your ATLANTIS, it is automatically tuned to channel 16, the United States Coast Guard frequency for distress, safety, and calling.  See the foldout in the front of the operating guide for button, knob, and key positions. Turning on the Unit and Setting Squelch 1. Before you turn on the unit, turn the Squelch knob fully counter clockwise. 2. Then, turn on the Unit by turning the Volume/Power knob clockwise until you hear a hissing sound. 3. Turn the Squelch knob clockwise, just until the hissing sound stops. Use the knob to adjust to the desired squelch level. Think of the squelch control as a frequency gate which controls access to weak or strong signals depending on its setting.  To listen to a weak or distant station, turn the knob counterclockwise.  If the tracking squelch control is adjusted so you continually hear a hissing sound, the unit will not scan properly. 4. To turn off the unit, turn the Volume/Power knob counterclockwise. 10
