4.13 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, Conventional,
MultiNet, and SMARTNET/SmartZone Systems. The radio can send the data as P25 data
on properly configured digital conventional systems.
4.13.1 Viewing GPS Data
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 (see Figure 2.3).
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.
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.
