Here is my keypad beep delete mod for the RPO-43:

1. Remove battery.
2. Remove back cover (4 screws).
3. Remove top board (6 screws, desolder two antenna connections and bend
   antenna ground lead up out of the way). Be careful of black connector at
   bottom of board. Flip board over and lay aside (wire connectors need not be
   disconnected).
4. Remove middle board (remove 2 screws and wire connector). Be careful of two
   multi-pin connectors along underside of board. Set middle board aside.
5. Locate 10 pin connector on side of bottom board (labeled CN3). Note that one 
   end of connector has pin 10 labeled as such. Count back to pin 6 and bend
   pin 6 ninety degrees towards the large RF shield. Make sure the bent pin
   clears the RF shield.
6. Reassemble and your done OR do the cell mod since you are so close.

Have fun. Gary Ross               >usual disclaimer>
