957 Operator's Manual, Rev. B
The serial number is located in the SERIAL NUMBER field (and
on the back of the 957).
The current version of the 957's operating software is located
in the SOFTWARE VERSION field.
If your 957 is connected to an optional Northstar radiobeacon
receiver, its software version will be displayed in this field.
If your 957 is connected to an optional Northstar radiobeacon
receiver, the receiver is automatically tested each time the 957
powers up. If all test parameters are met, the message PASSED
is displayed in the BEACON RCVR SELF TEST field. If the
differential receiver fails any of the test criteria, the 957
displays the message FAILED. In many cases, the failure is
caused by an open or shorted antenna cable, which can be
repaired in the field. If this isn't the source of the failure, you
may have to return the 957 to the factory for service.
The software version of the GPS receiver is located in the GPS
RCVR SOFTWARE VERSION field.
The GPS receiver's self-test message is displayed in the GPS
RCVR SELF TEST field. If the message FAILED is displayed, you
may have to return the 957 to the factory for service.
A built-in keypad test lets you check the integrity of the 957's
keys. This function works for all keys except PWR,
BRIGHTNESS, SAVE, and MOB key (pressing SAVE or MOB
during the keypad test saves a waypoint instead of testing the
keys).
On the OPTIONS/SERVICE INFO screen, press the MORE key to
display the MORE OPTIONS/SERVICE INFO screen. Press the
DIAGNOSTICS menu key, then the KEYPAD menu key.
Pressing each key identifies it on the screen.
