IN CASE OF EMERGENCY
If your vessel requires assistance, contact other vessels and the Coast Guard by sending a distress call on Channel 16.
A WARNING STICKER is supplied with the transceiver. To comply with FCC regulations, this sticker must be afxed in such a location as to be readily seen from the operating controls of the radio as in the diagram below. Make sure the chosen location is clean and dry before applying the sticker. (p. 31) EXAMPLE

WARNING.
USING DIGITAL SELECTIVE CALLING (Ch 70) DISTRESS CALL PROCEDURE
1. While lifting up the key cover, push and hold [DISTRESS] for 5 sec. until you hear 5 short beeps change to one long beep. 2. Wait for an acknowledgment on Channel 70 from a coast station. After the acknowledgment is received, Channel 16 is automatically selected. 3. Push and hold [PTT], then transmit the appropriate information as listed above.

RADIO OPERATOR WARNING
Icom requires the radio operator to meet the FCC Requirements for Radio Frequency Exposure.An omnidirectional antenna with gain not greater than 9 dBi must be mounted a minimum W ARN ING of 5 meters (measured from the lowest point of the antenna) vertically above the main deck and all possible personnel. This is the minimum safe separation distance estimated to meet all RF exposure compliance requirements. This 5 meter distance is based on the FCC Safe Maximum Permissible Exposure (MPE) distance of 3 meters added to the height of an adult (2 meters) and is appropriate for all vessels. For watercraft without suitable structures, the antenna must be mounted so as to maintain a minimum of 1 meter vertically between the antenna, (measured from the lowest point of the antenna), to the heads of all persons AND all persons must stay outside of the 3 meter MPE radius. Do not transmit with radio and antenna when persons are within the MPE radius of the antenna, unless such persons (such as driver or radio operator) are shielded from antenna eld by a grounded metallic barrier. The MPE Radius is the minimum distance from the antenna axis that person should maintain in order to avoid RF exposure higher than the allowable MPE level set by FCC. iii FAILURE TO OBSERVE THESE LIMITS MAY ALLOW THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION WHICH EXCEEDS THE FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT. IT IS THE RESPONSIBILITY OF THE RADIO OPERATOR TO ENSURE THAT THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT ALL TIMES DURING RADIO TRANSMISSION. THE RADIO OPERATOR IS TO ENSURE THAT NO BYSTANDERS COME WITHIN THE RADIUS OF THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS. Determining MPE Radius THE MAXIMUM PERMISSIBLE EXPOSURE (MPE) RADIUS HAS BEEN ESTIMATED TO BE A RADIUS OF ABOUT 3M PER OET BULLETIN 65 OF THE FCC. THIS ESTIMATE IS MADE ASSUMING THE MAXIMUM POWER OF THE RADIO AND ANTENNAS WITH A MAXIMUM GAIN OF 9dBi ARE USED FOR A SHIP MOUNTED SYSTEM.

BASIC OPERATION

I Channel selection

Channel 16
Channel 16 is the distress and safety channel. It is used for establishing initial contact with another station and for emergency communications. Channel 16 is monitored during both Dualwatch and Tri-watch. While standing by, you must monitor Channel 16. Push [169] momentarily to select Channel 16. Push [CH/WXDUAL] to return to the condition before selecting Channel 16, or push [Y] or [Z] to select operating channel.

Channel 9 (Call channel)

Each regular channel group has a separate leisure-use call channel. The call channel is monitored during Tri-watch. The call channels can be programmed (p. 9) and are used to store your most often used channels in each channel group for quick recall. Push [169] for 1 sec. to select the call channel of the selected channel group.
CALL and call channel number appear. Each channel group may have an independent call channel after programming a call channel. (p. 9) Push [CH/WXDUAL] to return to the condition before se-
lecting call channel, or push [Y] or [Z] to select an operating channel. Scrolls

BASIC OPERATION U.S.A.,Canadian and international channels
There are 57 U.S.A., 61 Canadian and 57 international channels. These channel groups may be specied for the operating area. q Push [CH/WXDUAL] to select a regular channel.
If a weather channel appears, push [CH/WXDUAL] again.

Weather channels

There are 10 weather channels. These are used for monitoring broadcasts from NOAA (National Oceanographic and Atmospheric Administration.) The transceiver can detect a weather alert tone on the selected weather channel while receiving the channel, during standby on a regular channel or while scanning. (p. 29) q Push [CH/WXDUAL] once or twice to select a weather channel.

Tri-watch starts.

Dualwatch

Tri-watch

Signal is received on call channel.
If a signal is received on Channel 16, Dualwatch/Tri-watch pauses on Channel 16 until the signal disappears. If a signal is received on the call channel during Tri-watch, Tri-watch becomes Dualwatch until the signal disappears. To transmit on the selected channel during Dualwatch/Triwatch, push and hold [PTT].
Signal is received on Channel 16 takes priority.
Tri-watch resumes after the signal disappears.

Page 12 (1,1)

SCAN OPERATION

I Scan types

Scanning is an efcient way to locate signals quickly over a wide frequency range. The transceiver has Priority scan and Normal scan. When the Weather alert function is in use, the selected weather channel is checked while scanning. (p. 29) PRIORITY SCAN

CH 01 CH 02

Set the tag channels (scanned channel) before scanning. Clear the tag channels which inconveniently stop scanning, such as those for digital communication use. Choose Priority or Normal scan in Set mode. (p. 29)

NORMAL SCAN

Priority scan searches through all tag channels in sequence while monitoring Channel 16. When a signal is detected on Channel 16, scan pauses until the signal disappears; when a signal is detected on a channel other than Channel 16, scan becomes Dualwatch until the signal disappears.
Normal scan, like Priority scan, searches through all tag channels in sequence. However, unlike priority scan, Channel 16 is not checked unless Channel 16 is set as a tag channel.

Page 13 (1,1)

I Setting tag channels
For more efficient scanning, add desired channels as tag channels or clear the tag for unwanted channels. Channels are not tagged will be skipped during scanning. Tag channels can be assigned to each channel group (USA, INT, CAN) independently. q Select the desired channel group (USA, INT, CAN) by pushing both [Y] and [Z]. w Select the desired channel to set as a tag channel. e Push [SCANTAG] for 1 sec. to be set the displayed channel as a tag channel.

D Scan type

The transceiver has 2 scan types: Normal scan and Priority scan. Normal scan searches all tag channels in the selected channel group. Priority scan searches all tag channels in sequence while monitoring Channel 16.

D Weather alert

A NOAA broadcast station transmits a weather alert tone before important weather information. When the weather alert function is turned ON, the transceiver detects the alert, then the WX ALT indicator blinks until the transceiver is operated. The previously selected (used) weather channel is checked any time during standby or while scanning.
WX ALT appears instead of WX indication when the function is set ON.

Normal scan (default)

Priority scan

D Scan resume timer

The scan resume timer can be selected as a pause (OFF) or timer scan (ON). When OFF is selected, the scan pauses until the signal disappears. When ON is selected, the scan pauses 5 sec. and resumes even if a signal has been received on any other channel than Channel 16.

D DSC watch

DSC watch monitors Channel 70 while you are receiving another channel. If a distress signal is received on Channel 70, the transceiver monitors Channel 16 and 70 alternately until the distress signal disappears. If a signal is received on another channel, DSC watch pauses until the signal disappears. This function may not be available for some channel groups depending on dealer setting.

I Mounting the transceiver
Using the supplied mounting bracket
The universal mounting bracket supplied with your transceiver allows overhead or dashboard mounting. Mount the transceiver securely with the 2 supplied screws (5 20) to a surface which is more than 10 mm thick and can support more than 5 kg. Mount the transceiver so that the face of the transceiver is at 90 to your line of sight when operating it. CAUTION: KEEP the transceiver and microphone at least 1 meter away from your vessels magnetic navigation compass. NOTE: Check the installation angle; the function display may not be easy-to-read at some angles.

EXAMPLE

I Optional MB-92 attachment
An optional MB-92 DUST COVER is available for attaching the transceivers front panel to prevent the keys and knobs getting wet when the transceiver is not used. Attach the optional MB-92 as shown below.
