The individual components of the NAVIKNOT system are not equipped
with power switches. All devices start up simultaneously, as soon as
supply power is applied to the system.
Upon power up, the startup routine is executed:
The startup screen is shown and a
system test sequence is executed.
A status line at the bottom of the
screen indicates the progress and
results of the following tests:
RAM test
I/O test
Checksum test
Setup Data test
After the system test, the indication
“WAITING FOR MAIN UNIT” may
be briefly shown at the CDU, while
the electronics unit initializes itself.
As soon as the system is fully oper-
ational, the actual speed over
ground and the daily and total mile

Note Should the NAVIKNOT electronics fail to establish communication with
the CDU(s) after power-up, the indication “waiting for main unit” will be
shown permanently at all connected CDUs. An audible alert is sounded
which must be locally acknowledged at each CDU.
The NAVIKNOT system will not operate properly until the cause of failure
is eliminated and should be powered down until it can be serviced.
