You will be able to tune continously from 80?whatever to 95?whatever

and this will include the appx 870 - 890 cellular band with the

proper 30 MHz steps for the cellular frequencies.



I haven't tried this modification to the PRO-46 so you will be on your own.

(note: The forwarder of the mod hasn't tried it, but I have and it works)

1.Remove battery pack, battery door and antenna.



2.Remove the 4 black screws on the back of the radio:push upward on bottom at

rear case and cantliever (swing) case half up from bottom to separete and

remove, its not necessary to remove belt clip.

(note: This sounds much easier than it is.  Be prepared to "prop and lever"

 around 3 catches in the battery case, along with one on each side around

 1/4 of the way down the case)



3.Carefully separate RF board from processor board by inserting eyeglass

screwdriver between board by plug-in connector.



4.Unsolder copper-coated plastic Rf shield from microprocessor and set aside.

 (note: If memory serves me correctly, this SHOULD be the side where the

  pushpad is.  In order to follow the rest of the instructions, place the

  scanner face down on a piece of cloth or in a clamp with the antenna facing

  AWAY from you).



5.Locate two resistors marked "0" (zero) on right side of board.

  (note: On mine they were labeled "000", not "0")



6.Carefully unsolder and remove BOTH of the resistors.



7.Reinstall ONE of the removed resistors (or jumper) on the UPPERMOST set of

  EMPTY solder pads.

   (note: These are located just to the left of where you just removed

    the two resistors.)



8.Thats it, reassemble the radio.



PS-Reintstall one of the removed zero marked resistors into top set of empty

solder pads. DO NOT install anything into LOWER SET of empty pads (cancels 30-

50 mhz and adds 68-88 mhz.
