may not reflect the correct local time.
10.4.5 Daylight Saving–Summer Time
The Daylight Saving Time or Summer Time (DST) configuration feature allows expanded settings.
The addition of AUTO allows the user to customize the DST settings to match the requirements of
locations in either Northern or Southern latitudes. For setup information through the front–panel
interface, please see Section 6.3.2.
DST configuration can be changed through the serial port or through the front panel keypad.
For setup information through the RS-232C port, please see Section 9.2.4.
10.5 Position Display Modes – 1084B/C
When the clock is first powered ON and acquiring satellites, the only position information available
is the previous position, stored in the clock setup EEPROM. This position information reflects the
location of the receiver as determined by the last position while locked to at least four satellites.
Displayed position will be based on the most recent position fix.
Press the POSITION key to access longitude, latitude, and elevation data values. Repeatedly
pressing the POSITION key scrolls the readout display continuously through these values. If pressed
prior to acquisition of enough satellites to accurately determine and update position data, these
numbers will reflect the receiver’s power-on defaults.
Synchronization to a minimum of four satellites is necessary for precise determination of longi-
tude, latitude, and elevation. When meeting this minimum satellite lock requirement, POSITION
values will accurately correspond to the present antenna location.
