Viking Portable 600 Radio Operating Manual

If this feature is enabled, GPS data can be received from satellites when a GPS receiver is 
attached to the side port of the radio. This can include accessories such as the Discover™ 
GPS Speaker Microphone, if the side port is so configured (see the microphone’s user 
manual for operational details). GPS data can be viewed using P25, Conventional, 
MultiNet, and SmartNet/SmartZone Systems. The radio can send the data as P25 data on 
properly configured digital conventional systems.

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

1 Connect the cable from the GPS receiver to the Accessory Connector on the side of the 

radio.

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

This will be indicated by the appearance of the satellite icon 

 on the display.

3 When the satellite icon appears, press the assigned GPS button (or select GPS from the 

menu). “GPS” will display briefly, and will be followed by one of the GPS data items:

- Latitude (e.g., 40

o

55.32’N)

- Longitude (e.g., 90

o

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) 

 

Press the F2 button to cycle to/from daylight savings time

- Date (e.g., 26NOV2008)

- Number of satellites that the receiver is currently receiving

4 You can cycle through the data items using the “Up” and “Down” buttons. If data is not 

available for an item, the display shows “No Data”.

5 To exit GPS viewing, press the assigned GPS button or press the “Clear” button (F1).
