3. ABOUT THIS RADIO
3.1 ABOUT THE VHF MARINE BAND
WARNING:
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 essentially “Line of sight” Actual transmission range
depends much more on antenna type, gain and height than on the power output of the transmitter. On
a fixed mount 25W radio transmission expected distances can be greater than 15 miles, for a portable
5W radio transmission the expected 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 waterway. If this occurs, depending upon the marine VHF channel on
which you are transmitting, you could interfere with a search and rescue case, or contribute to a
collision between passing ships. For VHF Marine channel assignments refer to page ?? section 11.
4. GETTING STARTED
If the radio has never been used, or its charge is depleted, it may be charged by connecting the
CD-38 Charger Cradle with the NC-88 battery charger, as shown in the illustration. If 12V DC

power is available, the optional 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 NC-88, E-DC-19A and
E-DC-6 will charge a completely discharged FNB-V99LI battery pack in about 8 hours.
4.1 BATTERIES AND CHARGERS
The FNB-V99LI is a high performance LI-ion battery providing high capacity in a compact package.
CAUTION
To avoid risk of explosion and injury, FNB-V99LI battery pack should only be removed, charged or
recharged in non-hazardous environments.
4.1.1 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
sufficient duration, it is possible to melt battery components. Do not place a loose battery pack on or
near metal surfaces or 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 fire or incinerator. The heat of fire 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 VERTEX STANDARD) 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

current channel is stored into the transceiver’s scan memory.
3. Repeat steps 1 and 2 for all the channels to be scanned.
4. To delete a channel from the transceiver’s scan memory, select the memorized channel, then
press and hold the [CLR(MEM)] key until “MEM” is removed from the display.
5. All channels programmed remain in the transceiver’s scan memory even if the power is turned
off.
6. Adjust the SQL level until background noise is eliminated by pressing the [SQL] key followed
by the [T] / [S] key.
7. To start scanning, press the [SCAN(DW)] key. The scan proceeds from the lowest to the highest
programmed channel and stops scanning when a transmission is received. Scanning will resume
when the incoming signal disappears at the end of the transmission. A “P-SCAN” icon will

appears at the upper left of the display during scanning.
As an example of priority scanning, let us say that marine channels “06”, “07”, and “08” are
memorized in the transceiver’s scan memory. Priority scanning will proceed in the following
sequence:
[CH06] Æ [Priority Channel] Æ [CH07] Æ [Priority Channel] Æ
[CH08] Æ [Priority Channel] Æ [CH06] Æ [Priority Channel] …………
8. Even when the transceiver stops and listens to the signal of a memorized channel, the
transceiver will shift to a “Dual Watch” mode between this channel and the priority channel.
Therefore, your priority watching of the designated channel is not compromised when the
scanner has paused on an active channel.
9. To stop the scan, press the [SCAN(DW)] key.
6.9 DUAL WATCH
The Dual Watch feature allows the radio watch the particularly important “Priority Channel”
(determined section “6.10 PRIORITY SCAN”) while receiving the current channel.
1. Select the desired channel using the [T] or [S] key.
2. Hold down the [SCAN(DW)] key for two seconds, then release the key to activate the Dual
Watch feature. A “TW-xx*” icon will appear on the upper left of the display when the Dual
Watch feature is activated.
*: Priority channel number.
3. When a transmission is received on the “Priority Channel”, the radio receives the “Priority
Channel” until the incoming signal disappears.
4. The Dual Watch feature will resume when the incoming signal disappears at the end of the
transmission.
5. Press the [SCAN(DW)] key to stop the Dual Watch feature and return to normal operation.
6.10 EMERGENCY (CHANNEL 16 USE)
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 transceiver is on and set to CHANNEL 16. Then use
the following procedure:
1. Press the microphone push-to-talk switch 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, fire, 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 microphone button and listen.
10. If there is no answer, repeat the above procedure. If there is still no response, try another
channel.
6.11 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. Calling should not exceed 30 seconds, but may be
repeated 3 times at 2-minute intervals. In areas of heavy radio traffic, congestion on channel 16
resulting from its use as a hailing channel can be reduced significantly 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 traffic, and
then go back to either channel 16 or 9 for your initial contact.
When the hailing channel (16 or 9) is clear, 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). When the
other vessel returns your call, immediately request another channel by saying “go to”, the number of
the other channel, and “over.” 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 microphone’s push-to-talk (PTT) switch. When all
communication 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
