3-6 Set the Priority Channel (WATCH MODE)

If you have the 721EU, watch mode is similar to a dual watch, scanning between the priority channel and the working channel. CH16 is the priority channel.

If you have the 721US and are operating on USA or Canadian channel banks, you can set the priority channel to cover both CH16 and CH09 as well as the working channel, as follows:

2.Select ONLY 16CH for dual watch mode, or 16CH+9CH for tri watch mode.

3-7 Weather Alert (WX ALERT)

721US only.

The NOAA provides several weather forecast channels on USA and Canadian channel banks. If severe weather such as storms or hurricanes are forecast, the NOAA broadcasts a weather alert on 1050 Hz. You can set up the radio to pick up weather alerts, as follows:

3.When a weather alert is broadcast, the alarm will sound. Press any key to hear the weather alert voice message.

3-8 NMEA or NAVBUS protocol (COM PORT)

You can add the radio to a group of instruments using NMEA or NAVBUS protocol.

NAVBUS is automatically activated when present, so that data such as barometric pressure and history, temperature, DSC polling positions and distress data are available to any other Northstar instruments using NAVBUS. However, the barometric and temperature readings from the radio can be turned OFF if you prefer to use the readings from a different instrument.

Select your GPS data source to come from either NMEA or NAVBUS as follows:
