REASON
The Postcode Security feature enables the end user to record their house postcode
into the VCR.  Whenever the VCR is powered on, the stored postcode will be
displayed for approximately five seconds on the television screen.
In the event of the VCR being stolen, this feature can be used to trace the original
owner.
When programming the postcode into the memory, it is also necessary to use a PIN
number.  This is to prevent unauthorised persons from erasing the Postcode Security
feature.
In the event that a service facility is requested to override this feature, they MUST first
ensure legal ownership of the VCR.  Note that if the customer moves or has lost the
original PIN number, they may request its removal.
ACTION
To change the PIN number so that the postcode can be reset, follow the procedure
outlined below:
1.  Remove the outer case and front cover.
2.  Select 'SET UP' from the main menu.
3.  Select the 'SECURITY CODE' option from the 'SET UP' menu.
4.  Locate the test pins P5007 on the main PWB.
5.  While displaying the menu screen above, short the pins of P5007 together.
6.  The PIN and postcode can now be entered, by following the instructions given in
the Service Manual.
