The file SHARC.IHX contains the data for the EPROM(*) in the EZANC-II.

WARNING:    Program only a new EPROM.  Keep the old EPROM as a
            fall-back until you have verified that the equipment works
            correctly with the new EPROM installed.

WARNING:    The following procedure must be performed by a
            qualified technician at a suitable workstation where the
            EZANC-II will be protected from damage by static discharge.

PROCEDURE:

1)  Disconnect power and RS232 and all signal leads from
    the equipment.

2)  Open the enclosure.  For this you need a hex driver
    (allen key).  Loosen the hex screws at the case top rear
    left and right corners (the screw head is hidden within the
    plasic feet on the case top rear corners).  The screws must
    be loosed but do not need to be removed.  They are captive
    within the plastic foot.

3)  Remove the lid by lifting up at the rear of the case and
    sliding away from the case front.  Place the lid on the
    desk next to the EZANC-II.

4)  Once the lid is removed the circuitboard containing the
    DSPs is clearly visible.  Identify the EPROM marked with
    ADSP21062 (SHARC) on the top circuit-board.

5)  Use a pair of wire cutters to cut the plastic cable-tie
    which holds the EPROM in its socket.

6)  Note the orientation of the EPROM by locating the notch
    in one end of the EPROM.  You must ensure that the new
    EPROM has the correct orientation.  Remove the EPROM from
    its socket.  Replace it with the supplied EPROM.

7)  Use the supplied cable tie to hold the EPROM in its
    socket.  This is necessary to prevent the EPROM
    self-ejecting during transport or storage.

8)  Replace the lid and tighten the hex screws at the top
    rear left and right corners of the lid.

The equipment is now ready for use.

(*) The EZANC-II contains two EPROMs: one each for two
separate processors.  Only the EPROM marked 'SHARC' needs
to be replaced with a new part containing the image found
in SHARC.IHX.
