Servicing Functions:
There are three further modes available within Super
User, which are used for servicing and maintenance
purposes. It is strongly recommended that these are
only accessed by Zero 88 staff or an appointed
Zero 88 dealer. However, they can be accessed in
the same way as before, using the ‘Up & Down’
Arrows to scroll through the memories and ‘Enter’ to
activate.
The “leds” function tests the segment display.
Pressing ‘Enter’ for 1 second will activate the test.
When activated the displays will begin to cycle
through a series of patterns.
“rdt” is used to test the hardware for RDM
functionality. Pressing ‘Enter’ for second will activate
the test. RDM functionality has been implemented in
hardware, however the current firmware does not
support the extra functionality. This test checks that
the hardware is functioning correctly.
“upgr” is used to re-programme the Demux 24’s
firmware. This can only be done in the factory.
