GEODETIC: Select the geodetic chart system you are using. WGS-84 (standard GPS chart system), can be directly selected. For other charts, select OTHER and enter chart number referring to Geodetic Chart List in the Appendix.

POS CALIB:Position calibration: You may apply an offset to po- sition generated by the internal GPS receiver, to further refine po- sition accuracy. The L/L position offset icon (L/L) appears on the display.

UNHEALTH: Every GPS satellite is broadcasting abnormal sat- ellite number(s) in the Almanac. Using this information, the GPS receiver eliminates any malfunctioning satellite from the GPS sat- ellite schedule. Once the malfunctioning satellite is returned to on-line status it is automatically restored to the satellite schedule when the Almanac is received. In some instances however the Al- manac may not contain information which announces that a satel- lite is now back on line. If you hear of this through another source, you can manually restore the satellite to the satellite schedule. Con- versely, you can manually disable a healthy satellite if you hear it is unhealthy.

To restore or disable a satellite, select RSTR or DISABLED on the UNHEALTH line and then enter satellite number.
