3. ABOUT THIS RADIO

3.1 ABOUT THE VHF MARINE BAND

The radio frequencies used in the VHF marine band lie between 156 and
158 MHz with NOAA Weather stations available between 161 and 163 MHz.
The marine VHF band provides communications over distances that are es-
sentially "line of sight," (VHF signals do not travel well through objects such
as buildings, hills or trees). Actual transmission range depends much more
on antenna type, gain and height than on the power output of the transmitter.
When transmitting using a fixed mount 25 W radio the expected transmission
distance can be greater than 15 miles, for a portable handheld 5 W radio the
expected transmission distance can be greater than 5 miles in "line of sight."
The user of a Marine VHF radio is subject to severe fines if the radio is used
on land. The reasoning for this is you may be near an inland waterway, or
propagation anomalies may cause your transmission to be heard in a water-
way. If this occurs, depending upon the marine VHF channel on which you
are transmitting, you could interfere with a search and rescue replace case
with operation, or contribute to a collision between passing ships. For VHF
Marine channel assignments refer to section "9. VHF MARINE CHANNEL
CHART ASSIGNMENT".
This radio is capable of transmitting on Marine VHF.
The FCC allows the use of VHF Marine band on water areas only. How-
ever the FCC does not allow the use of the VHF Marine band when
on land. If persons use the VHF Marine Band on land and interfere
with others communicating, the FCC will be notified and search for the
interference. Responsible parties found to be transmitting on the VHF
Marine Band on land could be fined up to $10,000 for the first offense.

3.2 ABOUT WATER RESISTANCE

The HX100/HX150 is only submersible
※ IPX7 Specification for submersibility: 3 ft. (1 m) for 30 minutes.

3.3 DISTRESS AND HAILING ( CHANNEL 16 )

Channel 16 is known as the Hail and Distress Channel. An emergency may
be defined as a threat to life or property. In such instances, be sure the trans-
ceiver is on and set to "Channel 16". Then use the following procedure:
1. Press the PTT (Push-To-Talk) switch and say "Mayday, Mayday, May-
