5 ABOUT THIS RADIO
5.1 PROHIBITED COMMUNICATIONS
The FCC prohibits the following communications:
• False distress or emergency messages:
• Messages to “any boat” except in emergencies and radio tests;
• Messages to or from a vessel on land;
• Transmission while on land;
• Obscene, indecent, or profane language (potential ne of $10,000).
5.2 ABOUT VHF RADIO
The radio frequencies used in the VHF marine band lie between 156 and 158
MHz with some shore stations available between 161 and 163 MHz. The marine
VHF band provides communications over distances that are essentially “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. On a xed mount
25W radio transmission expected distances can be greater than 15 miles, for
a portable 6W radio transmission the expected distance can be greater than
5 miles in “line of sight”.
5.3 DISTRESS AND HAILING (CHANNEL 16)
Channel 16 is known as the Hail and Distress Channel. An emergency may
be dened as a threat to life or property. In such instances, be sure the
transceiver is on and set to CHANNEL 16. Then use the following procedure:
1. Press the PTT (Push-To-Talk) button and say “Mayday, Mayday, Mayday.
This is , , ” (your vessel’s name).
2. Then repeat once: “Mayday, ” (your vessel’s name).
3. Now report your position in latitude/longitude, or by giving a true or magnetic
bearing (state which) to a well-known landmark such as a navigation aid
or geographic feature such as an island or harbor entry.
4. Explain the nature of your distress (sinking, collision, aground, re, heart
attack, life-threatening injury, etc.).
5. State the kind of assistance your desire (pumps, medical aid, etc.).
6. Report the number of persons aboard and condition of any injured.
7. Estimate the present seaworthiness and condition of your vessel.
8. Give your vessel’s description: length, design (power or sail), color and other
distinguishing marks. The total transmission should not exceed 1 minute.
9. End the message by saying “OVER”. Release the PTT button and listen.
10. If there is no answer, repeat the above procedure. If there is still no response,
try another channel.
Page 10
HX870
NOTE
The HX870 has the DSC Distress calling, that can transmit a distress
call digitally to all ships with compatible DSC radios. Refer to section
“10 DIGITAL SELECTIVE CALLING (DSC)”.
5.4 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)
Channel 16 may be used for initial contact (hailing) with another vessel.
However, its most important use is for emergency messages. This channel
must be monitored at all times except when actually using another channel.
It is monitored by the U.S. and Canadian Coast Guards and by other vessels.
Use of channel 16 for hailing must be limited to initial contact only. Call-
ing should not exceed 30 seconds, but may be repeated 3 times at 2-minute
intervals. In areas of heavy radio trafc, congestion on channel 16 resulting
from its use as a hailing channel can be reduced signicantly in U.S. waters
by using channel 9 as the initial contact (hailing) channel for non-emergency
communications. Here, also, calling time should not exceed 30 seconds but
may be repeated 3 times at 2-minute intervals.
Prior to making contact with another vessel, refer to the channel charts in this
manual, and select an appropriate channel for communications after initial
contact. For example, Channels 68 and 69 of the U.S. VHF Charts are some
of the channels available to non-commercial (recreational) boaters. Monitor
your desired channel in advance to make sure you will not be interrupting
other trafc, and then go back to either channel 16 or 9 for your initial contact.
When the hailing channel (16 or 9) is clear, press the PTT button and state the
name of the other vessel you wish to call and then “this is” followed by the
name of your vessel and your Station License (Call Sign) then release the PTT
button. When the other vessel returns your call, immediately request another
channel by pressing the PTT button and saying “go to”, the number of the
other channel, say “over” and release the PTT button. Then switch to the new
channel. When the new channel is not busy, call the other vessel.
After a transmission, say “over”, and release the PTT button. When all commu-
nication with the other vessel is completed, end the last transmission by stating
your Call Sign and the word “out”. Note that it is not necessary to state your
Call Sign with each transmission, only at the beginning and end of the contact.
Remember to return to Channel 16 when not using another channel. Some
radios automatically monitor Channel 16 even when set to other channels or
when scanning.
Page 11
HX870
5.5 MAKING TELEPHONE CALLS
To make a radiotelephone call, use a channel designated for this purpose.
The fastest way to learn which channels are used for radiotelephone trafc
is to ask at a local marina. Channels available for such trafc are designated
Public Correspondence channels on the channel charts in this manual. Some
examples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87. Call
the marine operator and identify yourself by your vessel’s name. The marine
operator will then ask you how you will pay for the call (telephone credit card,
collect, etc.) and then link your radio transmission to the telephone lines.
The marine telephone company managing the VHF channel you are using may
charge a link-up fee in addition to the cost of the call.
5.6 BRIDGE CHANNELS 13 AND 67
Channel 13 is used at docks, bridges and by vessels maneuvering in port.
Messages on this channel must concern navigation only, such as meeting and
passing in restricted waters.
Channel 67 is used for navigational trafc between vessels.
By regulation, power is normally limited to 1 Watt on these channels. Your radio
is programmed to automatically reduce power to this limit on these channels.
However, in certain situations it may be necessary to temporarily use a higher
power. See Page xx for means to temporarily override the low-power limit on
these two channels.

HX870
5.7 AUTOMATED RADIO CHECK SERVICE
In areas across the country, Sea Tow offers boaters a way to conduct radio
checks. To use Sea Tow’s free Automated Radio Check service, simply tune
your VHF radio to the appropriate channel for your location and conduct a
radio check as you typically would. Upon releasing your radio’s microphone,
the system will play an automated message and relay your transmission back
to you, thereby letting you know how your signal will sound to other boaters.
The Automated Radio Check Service is currently available in the areas listed
below.

6 GETTING STARTED
NOTE
Before operating the HX870 for the rst time, it is recommended that
the battery be charged. Please see section “6.1.4 Using the SBH-12
Charger Cradle” for details.
6.1 BATTERIES AND CHARGERS
If the radio has never been used, or its charge is depleted, it may be charged
by connecting the SBH-12 Charger Cradle with the SAD-11B battery charger,
as shown in the illustration. If 12V DC power is available, the E-DC-19A DC
Cable with 12 V Cigarette Lighter Plug or the optional E-DC-6 DC Cable may
be used for charging the battery. The SAD-11B, E-DC-19A and E-DC-6 will
charge a completely discharged SBR-13LI battery pack in about 3 hours.
The SBR-13LI is a high performance Li-ion battery providing high capacity in
a compact package.

CAUTION
To avoid risk of explosion and injury, SBR-13LI battery pack should only
be removed, charged or recharged in non-hazardous environments.
6.1.1 Battery Safety
Battery packs for your transceiver contain Li-ion batteries. This type of battery
stores a charge powerful enough to be dangerous if misused or abused,
especially when removed from the transceiver. Please observe the following
precautions:
DO NOT SHORT BATTERY PACK TERMINALS: Shorting the terminals that
power the transceiver can cause sparks, severe overheating, burns, and battery
cell damage. If the short is of sufcient duration, it is possible to melt battery
components. Do not place a loose battery pack on or near metal surfaces or
Page 14
HX870
objects such as paper clips, keys, tools, etc. When the battery pack is installed
on the transceiver, the terminals that transfer current to the transceiver are not
exposed. The terminals that are exposed on the battery pack when it is mounted
on the transceiver are charging terminals only and do not constitute a hazard.
DO NOT INCINERATE: Do not dispose of any battery in a re or incinerator. The
heat of re may cause battery cells to explode and/or release dangerous gases.
Battery Maintenance
For safe and proper battery use, please observe the following:
Battery packs should be charged only in non-hazardous environments;
Use only STANDARD HORIZON-approved batteries;
Use only a STANDARD HORIZON, (a Marine Division of YAESU USA)
approved charger. The use of any other charger may cause permanent
damage to the battery.
Follow charging instructions provided with the chargers.
Keep the battery contacts clean.
Battery Storage
Store the batteries in a cool place to maximize storage life. Since batteries are
subject to self-discharge, avoid high storage temperatures that cause large
self-discharge rates. After extended storage, a full recharge is recommended.
Battery Recycling
