INITIATE COLD BOOT
This menu lets the user initialise all GPS data’s, i.e. all saved satellite data’s will be
cleared. The user has to acknowledge this menu again before the initialisation starts.
The system starts operating in the COLD BOOT mode and seeks for a satellite to read
its actual parameters.
SETUP
INIT COLD BOOT
Are you sure ?
Press …
INC -> YES
MENU -> NO
INITIATE WARM BOOT
This menu lets the user force the receiver into the Boot Mode. This may be
necessary when the satellite data in the memory are too old or the receiver position
has changed by some hundred kilometres since last operation. Synchronisation time
may be reduced significantly. If there is valid satellite data in the memory the system
starts in the WARM BOOT mode, otherwise the system changes into COLD BOOT
to read new data’s.

ANTENNA CABLE
This menu asks the user to enter the length of the antenna cable. The received time
frame is delayed by approx. 5 ns per meter antenna cable. The receiver is able to
compensate this delay if the exact cable length is given. The default value is 20 m.
The maximum value that can be entered is 500 m (only with low loss cable).

Resetting Factory Defaults of the GPS
If both, the NEXT key and the INC key on the front panel, are pressed while the
system is powered up the battery buffered memory is cleared and user definable
parameters are reset to factory defaults. The key should be held until the root menu is
displayed on LCD. Due to the fact that the satellites parameters have been cleared, the
system comes up in COLD BOOT mode. The network and NTP parameters will not
be changed.
