Enabling WX (Weather) Alerts

You can enable your radio to continually monitor NOAA weather alerts. If the radio detects

NOTE:

 When you enable weather alerts, the radio only monitors the last monitored weather 

channel.

Channel

 knob to access WX mode.

2.  Select

Channel

 knob to return to the Home screen.

Automatic Transmitter Identification System

The Automatic Transmitter Identification System (ATIS) is a vessel identification 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 identification number (see below), and then turn on ATIS 

(see 

page 13

). Contact your Garmin dealer to determine your ATIS identification 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.
