Note the slightdifference in the amount of information available between the twomodels.MX420/2 GPS6 Screen MX420/8 GPS6 ScreenStatus will tell you whether the correction data is being decoded iserror free or not. Normally, Status will indicate either DGPS mode Off,DGPS OK, Tracking or Searching (Automatic search mode) or NoLock (Manual tuning mode). DGPS OK indicates that RTCM SC-104DGPS corrections are being received without errors within the AgeLimit set in CFG1 DGPS. These information originates from the MX421Bbeacon receiver. Searching indicates that the beacon receiver is search-ing for the appropriate frequency and/or modulation of the beacontransmitter in automatic search mode. No lock indicates that the bea-con receiver is not receiving DGPS corrections from the selected sta-tion in manual tuning mode. You might see the label Tracking, whichindicates that a MSK beacon signal is present but DGPS correctionsare not being received. This is usually caused by high noise on thebeacon receiver or external device.If you press the E key, you can select between Automatic beaconsearch mode, Manual beacon tuning mode, or Off. When the receiveris in the Manual tuning mode, you can use the cursor key to scrolldown into the large window below Station Selection and edit theReference Station name. The name you enter will always be associ-ated with the frequency to which you programmed the receiver. If youmove to another region that uses a frequency and name you previ-ously entered, the receiver will display the previously entered name.You can enter a new name for any manually tuned frequency at anytime.
