Getting Started Getting Started
Getting Started
•
Refer to the foldout at the front of this manual to identify the
various controls and indicators on your radio. Throughout
this manual you will be instructed to “Press” or to “Press
and Hold” various buttons (except “Push to Talk”) on the
radio. “Press” means a momentary press of approximately
one (1) second. “Press and Hold” means to hold the button
down for approximately three (3) seconds.
Whenever you press any button except the Talk button on
your radio, a brief tone (beep) will sound to confirm the
button press. With all button presses, the appropriate icon
will appear on the LCD and the backlight will turn On. The
backlight will stay on for 10 seconds after the button is
released.
At times, you will hear two (2) other sounds. Two (2) beeps
will sound to confirm your setting changes and three (3)
beeps will sound to notify you of an error.
Common Radio Functions
The following procedures define common operating
functions of the radio when in either Marine Standby or
Weather (WX) Standby modes.
Power/Volume/Squelch Controls
Power On/Off Control
The On/Off/Volume control is located at the upper right
side of the radio. Turning the On/Off/Volume control
past the detent position will turn the radio On or Off.
Volume Control
Volume is controlled by turning the On/Off/Volume
control.
■ To increase the volume, turn the On/Off/Volume
control clockwise.
■ To decrease the volume, turn the On/Off/Volume
control counterclockwise.
Squelch Control
Squelch is controlled by turning the lower rotary
concentric knob located directly below the
On/Off/Volume switch.
With the power On, turn the knob counterclockwise
until you hear a hissing sound, then turn the knob
clockwise until the hissing stops. This will establish a
“Baseline” squelch. By turning the knob further in a
clockwise direction, you will filter weak and medium-
strength signals. By turning the knob in a
counterclockwise direction (further from your baseline
setting), you will receive weaker signals. Squelch
Control filters weak signals and radio frequency (RF)
noise so that you will clearly hear the signals you want.
NOTE
If the Squelch is set so that you can hear a
continuous hissing sound, the Memory Scan and
Tri-Watch functions will be blocked.
Radio Speaker and Microphone
The internal Radio Speaker and Microphone are located on
the bottom front face of the radio below the lower control
buttons.
An optional Speaker/Microphone port is located at the top
of the radio between the antenna and the Power/Volume/
Squelch control. Unthread the Speaker/Microphone port
cover to access and install an optional speaker or
microphone into this port.
Talk Button
Press and hold the Talk button to transmit messages.
Release the Talk button to stop transmitting.
