Place the radio with the front panel toward you and
bottom side / speaker side UP.

Remove the (4) screws located in each corner.


CAREFUL! Go slow, you will need to disconnect the
speaker cable while removing the cover.
Look at the lower right hand corner of the main
printed circuit board.

You should see a silver crystal with the number
"D196D3C" printed on it.


Just above the crystal, you should see an (8x8) matrix
pad (see below diagram).

Note: there are ONLY (2) resistors in place. (Bottom
right and the one directly above it).


REMOVE BOTH RESISTORS [Do NOT attempt this unless you
know how to use a low wattage soldering iron]


RESET THE RADIO, hold the [SET LOCK] and [S.MW-MW]
buttonsdown during power-up.
