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

2 Enter your current coordinates and the present time (Entering Text, page 9).
3 Select ACCEPT.
