Operation • See "Controls and Indicators" (page 2) for button, knob, and key positions. • When you turn On your MHS350 for the first time after purchasing, it is automatically tuned to channel 16, the United States Coast Guard frequency for distress, safety, and calling. From the second time, the radio turned to the channel which was selected before you turn off the radio. • When you press any button (except PTT), a short tone sounds. Turning On the Unit and Setting Squelch 1 Before you turn On the unit, turn the squelch (SQ) knob fully counterclockwise. 2 Then, turn On the unit by turning the Volume/Power (VOL) knob clockwise until you hear a hissing sound. 3 Turn the SQ knob clockwise, just until the Strong Signals hissing sound stops. Use the knob to adjust Medium Signals to the desired squelch level. Think of the squelch control as a frequency gate which Weak Signals controls access to weak or strong signals Noise depending on its setting. • To listen to a weak or distant station, turn the knob counterclockwise. If reception is poor, turn it clockwise to cut out weak transmissions. • If the squelch control is adjusted so that you continually hear a hissing sound, the unit will not scan properly. 4 To turn Off the unit, turn the VOL knob counterclockwise until it clicks. 11
