7.6 Automatic Transmitter
Identification System (ATIS)
and Marcom-C mode
ATIS is a European system used on some inland
waterways.
VHF radios operating in an ATIS region must be
programmed with a unique ATIS number; this can be
obtained from the relevant licensing authority. The
ATIS number is attached as a digital signal at the end
of each transmission and identifies you to the relevant
authorities who monitor the system.
When operating in ATIS mode, some of the products
features are not available:
• Use of DSC functions is not permitted in ATIS regions.
• Watch modes are not permitted in ATIS regions.
• Channel scanning is not permitted in ATIS regions.
• ATIS regulations restrict the transmit power to 1 watt
for the following channels: 6, 8, 10, 11, 12, 13, 14, 71,
72, 74 and 77.
You can enable or disable ATIS using the menus (except
on Marcom-C configured units).
Marcom-C mode
Marcom-C mode is a restricted radio configuration
for VHF operators with a Marcom-C license. This is
applicable to radios operated exclusively in European
inland waterways using the ATIS system.
A Marcom-C VHF radio has the ATIS permanently
enabled. You will not be able to disable ATIS operation.
Marcom-C operation is set by the dealer at point of sale.
If you wish to enable or disable Marcom-C mode, you
must contact your Raymarine dealer.
For further information please contact Raymarine
technical support.
