Notes :
The first three lines of this print out are simply a test of the printer.
The ROMDATE and ROM lines change in line with product development.
The DISPLAY line tests the LCD display module.
The RAM and CPU lines test the memory and central processor.
The RXA-I and RXA-Q lines test the two signal paths in the 518 kHz radio
receiver.
The RXB-I and RXB-Q lines test the two signal paths in the 490 kHz radio
receiver.
The PAPER SENSOR tests whether the unit can recognise the presence of
paper in the roll holder.
The HEAD RESISTANCE letter is for service use only, and should match
the head resistance mark on the printer assembly.
This self-test is carried out automatically each time the unit is switched on,
but the results are not reported unless a fault is detected.
Three beeps mark the progress of this test.
As an additional receiver confidence test, the ICS NAV5plus also flashes
two small squares at the right hand side of the display whenever it is
receiving a NAVTEX signal, even if the message is not selected for printing.
