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.
