ATIS

EU models only.
The Automatic Transmitter Identification System (ATIS) is
mandatory for vessels navigating on some European waterways.
The system allows authorities to monitor and regulate VHF radio
communications by identifying any vessel that makes a VHF
transmission. Each vessel is required to have an ATIS-enabled radio
on board and is allocated a unique ATIS Maritime Mobile Service
Identity (MMSI).
Each time a radio operator finishes talking and releases the PTT key,
the radio transmits a short digital message, which includes the ATIS
MMSI. The receiving station can then look up details of the vessel,
saving time in communication on the busy VHF channels.
Unlike DSC, the ATIS signal is transmitted on the same VHF channel
as the voice transmission.
Before you can enable ATIS, you must enter the ATIS MMSI. See
"Entering or checking your ATIS MMSI" on page 97.
Before you can enable ATIS, DSC must be turned off. See "Enabling
DSC functionality" on page 98. To enable ATIS, see "Enabling ATIS
functionality" on page 97.
¼ Notes:
•
ATIS is disabled in US models.
•
When ATIS is enabled, the ATIS icon appears on screen.
•
In some European countries SCAN functionality is limited, and, if ATIS
is enabled, the 3CH SCAN and Dual scan modes will be disabled.
