To send a distress call:
1. Confirm that a distress call is not being received from another vessel.
2. Lift the cover on the [DISTRESS] button and push and hold the button for 5 seconds.
The distress call is transmitted on channel 70 and is repeated every 4 minutes until an acknowledgment
call is received on channel 70. When an acknowledgment is received you reply to the connected station
using the microphone. The distress message goes out as "undesignated" for the nature of the distress
unless you have previously selected an alternative designation from the menu. Refer to the manual
page 21 for information on how to select alternative distress messages.
Intercom Operation:
1. Push [LO/DX-IC-SCR] and hold for 1 second.
2. Push and hold [LO/DX-IC-SCR] again - the transmitter and microphone will emit call beeps.
3. Push and hold the PTT microphone switch and speak at a normal voice level into the
microphone.
4. After releasing the PTT button you can hear the response through the speaker.
5. To return to normal operation, push [LO/DX-IC-SCR] momentarily.
3. SSB Radio
The SSB radio operates much like the VHF radio. Details of operation are given in the operating
manuals that are stored in the Windward Passage file box. There are a total of 160 frequencies pre-
programmed. A list of these frequencies is given in the navigation table storage area under the desk
top.
The propagation for SSB radio is dependent on the frequency and the atmospheric conditions.
Consequently, in an emergency you will have to try each of the Coast Guard emergency channels
(channels 6 though 11) until you make a contact.
The Maritime Net (channel 40) operates on a frequency of 14300.0 KHz from noon to 9:30 p.m. and
will provide emergency assistance if possible. Technically, one needs a ham license to operate on this
frequency but in an emergency they will correspond with you. I have a ham license (KB3EFY) and try
to contact them daily when off shore.
4. Radar/Chart Plotter
Details for the operation of the Radar/Chart Plotter are in the operating manual stored with the other
operating manuals. Summary cards are in the navigation table desk top that should enable one to do the
basic functions.
To turn the unit on you must hold the power button in for a few seconds. To turn the unit off you must
hold the power button in while a countdown sequence is completed on the screen. The radar consumes
appreciable power when transmitting so it is wise to keep it on standby when the conditions allow you
to do so safely. To change from standby to transmit or from transmit to standby briefly press the power
button.
