NOTE: When you enable weather alerts, the radio only monitors the last monitored weather
channel.

2. Select ALERT.
3. Select EXIT or press the Channel knob to return to the Home screen.
The icon indicates that WX alerts are enabled.

Automatic Transmitter Identication System
The Automatic Transmitter Identication System (ATIS) is a vessel identication system
that can be used on certain inland waterways in certain countries throughout Europe. Your
Garmin dealer can program your VHF 300i or VHF 300i AIS to use ATIS if you plan to
use your radio on waterways that are within the bounds of the Regional Arrangement
Concerning the Radiotelephone Service on Inland Waterways (the Basel Agreement). The
use of ATIS is prohibited outside the European inland waterways covered by the Basel
Agreement.
When you enable ATIS, a data signal identifying your station is sent at the end of every
transmission. Data identifying your position is not sent; however, your position is calculated
through the method of triangulation by coastal stations receiving your transmissions.
To enable ATIS, enter your ATIS identication number (see below), and then turn on ATIS
(see page 13). Contact your Garmin dealer to determine your ATIS identication number
and to learn about ATIS requirements for your region.
Your radio disables the following functions when you enable ATIS:
Digital Selective Calling (DSC)
Dual watch and Tri watch
Channel scanning
The following International channels are restricted to transmit on low-power (1 watt) when
you enable ATIS: 6, 8, 10, 11, 12, 13, 14, 71, 72, 74, and 77.
