of-the-art in high-tech engineering. Designed for international

operation. Thisallows you to transmit and receive on all international
channels in the VHF marine band, as assigned by the in ternational
Union (ITU). This unit is a quality piece of electronic equipment,
skillfully constructed with the finest components. It is approved with
commercial-grade standards to give you clear, reliable communication.

Your radio is designed for many years of reliable, trouble-free
performance. It is under control of a microprocessor resulting in
enhanced features and performance. The microprocessor controls
not only the marine band tuning but also dual watch, memory
channels, and a host of other useful features.

Your radio has the following features:

Channel 16 Switch -------- provides quick access to channel 16, the
universal marine frequently used channel.

PLL (Phase Lock Loop) Controlled Circuitry ---- Provides accurate
and stable channel selection.

SAFETY INFORMATION

Your hand-held marine VHF radio is NOT approved for use by the
general population in an uncontrolled environment. This radio is
restricted to occupational use, work related operations only where
the radio operator must have the knowledge to control its RF exp­osure conditions.

1. When transmitting, hold the radio in a vertical position with its
microphone 1 to 2 inches (2.5 to 5 cm) away from your mouth
and keep the antenna at least 1 inch (2.5cm) away from your
head and body.

2. The radio must be used with a maximum operating duty cycle
not exceeding 50%, in typical Push-to-Talk (Manual PTT) co­ nfigurations.

DO NOT transmit for more than 50% of total radio use time
(50% duty cycle). Transmitting more than 50% of the time
can cause FCC RF exposure compliance requirements to be
exceeded.
The radio is transmitting when the "TX" icon on the LCD splay.
You can cause the radio to transmit by pressing the PTT button.
