- PRO2004.8
-
- The PRO-2004 scanner can be used to receive cellular telephone
- conversations. Originally, the scanner was able to receive in this
- band, but at the last minute, it was decided to delete cellular
- coverage from the PRO-2004.
-
- The procedure to re-instate the cellular band is simple for anyone
- with a pair of cutters, and a phillips screw-driver.
-
- 1. Remove the four screws from the back of the radio, and slide
- off the cover from the chassis.
-
- 2. Turn the radio upside down. You will find a metal box-like sub-
- chassis in the center of the main chassis. Remove the cover and
- you will be looking at the CPU, a 64-pin integrated circuit.
-
- 3. Examine the component side of this board, and you will find a row of
- diodes and resistors. On one end of the row you will find a diode
- labeled D-513.
-
- 4. Clip the accessible end of D-513, and pry apart the ends so they
- don't touch. You have just restored cellular coverage to you scanner.
-
- 5. If D-513 is not there, it may be located on the underside of
- the circuit board.
