If this feature is enabled, GPS data can be received from satellites when a GPS receiver is 
attached to the serial port of the radio. GPS data can be viewed using P25, Conventional, 
MultiNet, and SMARTNET/SmartZone Systems.

To use the GPS feature (on a properly configured radio):

1 Connect the cable from the GPS receiver to the Accessory Cable on the back of the 

radio (see Figure 2.8).

2 Press the assigned GPS button (or select GPS from the menu). “NO SAT REC” will 

display initially.

3 Wait until the GPS receiver acquires enough satellites to obtain a valid position fix.

When the system acquires a fix, one of the following GPS data items will appear on the 
display:
- Latitude (e.g., 40

55.32’N)

- Longitude (e.g., 90

23.41’W)

- Altitude in meters (e.g., 390.2)
- Speed (e.g., 55.5 MPH)
- Course Over Ground (e.g., COG 183.4

o

- Time (e.g., 14:23:15)
- Date (e.g., 26NOV2008)
- Number of satellites that the receiver is currently receiving
