The ‘DGPS Rcvr’ and ‘Diff SNR’ fi elds appear below the ‘Accuracy’ and ‘DOP’ fi elds. The Differential 

Receiver status will show one of the following:

• Off— No optional beacon receiver attached or enabled in the Comm menu

• No Signal— DGPS receiver attached, but not transmitting RTCM data to GPS

• Tuning— Receiver is tuning manual frequency

• Scanning— DGPS receiver is scanning for available frequency

• Rcving— Unit is receiving DGPS corrections

• Chk Wiring— DGPS is enabled in Comm menu, but no DGPS receiver attached or bad corrections

• WAAS— The unit is receiving ‘WAAS’ data

The Differential SNR (Signal to Noise Ratio) indicates, on a scale to 0-30db with 30db being the 

best, the strength of the DGPS signal being received. If no optional DGPS receiver is used with the 
GPSMAP 168 Sounder, the ‘DGPS Rcvr’ fi eld will display ‘Off’ and the ‘DGPS SNR’ fi eld will be blank. 
The SNR will depend upon the mounting of your DGPS receiver and the distance from the DGPS 
transmitting station.
