GPS receiver self-test and software revision
The internal GPS receiver runs a self-test each time you
power-up. The box on the right of the GPS RCVR ST/REV field
displays the software version used by your GPS receiver, and
the self-test message PASS or FAIL is displayed on the left.
This box should read PASS, not FAIL. If the message FAIL is
displayed, return the 961/962 to Northstar for service.
Processor memory
The MEMORY field displays the amount of memory currently
installed, and is used for diagnostic purposes only.
The RECEIVER INFORMATION screen provides you with
access to several of the GPS and DGPS receiver (if installed)
functions. To display these functions, press the STAR key until
you reach the SERVICE MENU screen, then press the
RECEIVER SETUP key.
