Manual Position Information
If you do not have a GPS device connected to your radio, you can manually enter your position and time of
entry. The position data is transmitted with DSC calls. When you enter the position and time manually, MANUAL
POS appears on the screen.
Manually entered position information must be updated regularly, and the radio displays two alerts to remind
you to update the position data.
• When the position data you entered manually is more than four hours old, DATA IS OVER 4 HOURS OLD
appears on the screen. The radio continues to transmit this position data, but you should update it before it
becomes invalid.
• When the position data you entered manually is more than 23.5 hours old, it is considered invalid and DATA
IS INVALID appears on the screen. The radio does not transmit invalid position data, and you should update
it immediately.
Entering Position Information Manually

Changing the Channel to 16 Automatically

urgency calls. In certain situations, when you must continually monitor a channel to maintain uninterrupted
communication with another vessel, for example, you can disable this feature.

channel automatically for all incoming individual calls.
