							Charging the Battery Pack
Your marine radio is powered by a specially designed Ni-MH
battery pack.
• Before operating the MHS350, charge the Ni-MH battery pack for
4 hours 
without interruptionwith the Adapter.
Plug one end of the AC adapter into the
wall outlet and the other end into the
Adapter jack on the side of the Charging
Cradle.
Make sure your radio is OFF, and place the
radio in the front of the Charging Cradle. You
can also charge another battery at the same
time. Place it in the back of the Charging
Cradle.
Charge the battery for about 4 hours.
• The charger won’t overcharge the battery pack.
When the LED on the Charging Cradle turn off,
charging is completed.
•The radio will not charge the battery while on and receiving
incoming voice traffic, and while transmitting.
• When you mount the Charging Cradle on your boat, use the DC
adapter instead.
• The jack is for charging only. If the battery level is low, the radio
needs to charge before use.
• If the LED on the charging cradle flashes, the battery might be
broken. Purchase Uniden BP350 battery (see page 29).

							Operation
• See “Controls and Indicators” (page 2) for button, knob, and 
key positions.
• When you turn On your MHS350for 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 
SQknob 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.4
