Viking™ VP600 Portable Radio Operating Manual
Radio-wide Features
4.12 Global Positioning System (GPS)
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 Trunked, 
Conventional, and SmartNet/SmartZone Systems. The radio can send the data as P25 data 
on properly configured digital conventional systems.
4.12.1 Viewing GPS Data
To use the GPS feature (on a properly configured radio):
Connect the cable from the GPS receiver to the Accessory Connector on the side of the 
radio.
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.
Note
It may take up to 10 minutes, depending upon signal conditions, for the GPS receiver to 
obtain a position fix. Failure of the icon to appear indicates that the receiver was unable 
to obtain a fix.
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)
- Bearing (e.g., 183.4
°)
- Time (e.g., 14:23:15) 
- Date (e.g., 2011/11/26)
- Number of satellites that the receiver is currently receiving
You can cycle through the data items using the “Up” and “Down” buttons. If data is not 
available for an item, the display shows “NA”.
Note
The GPS viewing mode remains active for 60 seconds after the last user input.
To exit GPS viewing, press the assigned GPS button or press the 
 (Clear) button.
