b. If the radio is in its standby mode, the radio automatically sends an individual
acknowledgement. Depending on the calling radio's capabilities, your radio's station
name or user MMSI, category code, INDIVIDUAL, and the channel number might appear
on the display of the calling radio.
Notes:

turned on, the radio automatically changes the channel.
Using DSC Group Call
DSC group call lets you transmit a DSC call to a group of stations with the same group
MMSI. You can also receive DSC group calls from other stations.
Note: You must set a group MMSI before you can use DSC group call. See "Setting Up a
Group MMSI" on Page 38 for more information.

2. Repeat Steps 3-4 under "Using DSC Individual Call" on Page 26 to send a DSC group
call.
If you receive a DSC group call from another radio, the radio sounds a tone.
Using DSC ALL SHIPS Call
DSC ALL SHIPS call lets you transmit DSC Calls to all ships. You can also receive DSC ALL
SHIPS calls from other stations. DSC ALL SHIPS calls consist of URGENCY and SAFETY
calls.
Note: The radio automatically sets itself to high power when it sends a DSC ALL SHIPS call.
1. Rotate PUSH/SELECT to select ALL SHIPS, then press PUSH/SELECT to select it.
2. To select the type of DSC ALL SHIPS call you want to send, rotate PUSH/SELECT until
URGENCY or SAFETY is highlighted, then press PUSH/SELECT to select it.
To send the DSC ALL SHIPS call you selected, rotate PUSH/SELECT to select SEND, then
press PUSH/SELECT to select it.
