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
Before you turn On the unit, turn the
squelch (
SQ
) knob fully counterclockwise.
Then, turn On the unit by turning the
Volume/Power (
VOL
) knob clockwise
until you hear a hissing sound.
Turn the
SQ
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 counter-
clockwise. 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.
To turn Off the unit, turn the
VOL
knob counterclockwise until
it clicks.
