5.6 All Ships Calls
An All Ships Call sends out a message to all stations within range. The Ray218E/
Ray55E can make All Ships Safety Calls for advisory alerts and Urgency Calls when
assistance is required but life is not in danger. For example, you might send a
Safety Call to warn others there is a large floating object that may be a hazard to
navigation. A sample Urgency Call might be that you have an illness or an
accident on board. The All Ships Call is made on channel 70, and then the radio
automatically switches to channel 16 at high power for voice communications.

2. Select the type of call you wish to make: URGENCY or SAFETY.
3. Press SEND to transmit the call. The call is transmitted on channel 70, and
then the radio tunes to channel 16 at high power.
4. Press OK to reconfirm the All Ships Call. The radio returns to standby mode.
