Known Faults

To date there have been very few re occurring faults, most problems relate to the use
of very early firmware, please see above
There is one known hardware problem that has occurred on a few occasions and that
is detailed below:

1. Failure of Keyboard buttons

This fault is exhibited by a total lack of any operation being possible from the Record,
Play or Menu keys.
This is caused by the socket that is mounted on the Connector PCB [009] becoming
disconnected from the Connector PCB and requires disassembly of the unit as detailed
in disassembly steps 1-5 above.
It will be found that when the Keyboard PCB [010] that the CPU PCB connector is
attached to the plug

The connector can then be re soldered onto the PCB note that there are small
alignment pips on the socket to locate the socket square in the PCB, it is most
important to ensure the socket is square to the PCB once soldering is complete.
