- PRO-2006 Modifications
-
- NOTE: The Electronic Communications Privacy Act of 1986 makes it
- unlawful to monitor mobile telephones, including cellular. The following
- modification is intended only to restore continuous 760-1300 MHz
- coverage as originally provided by the design of the PRO-2006
- microprocessor.
-
- BE SURE TO TEST YOUR PRO-2006 FULLY BEFORE ATTEMPTING THIS
- MODIFICATION. ANY MODIFICATION MAY VOID YOUR WARRENTY.
-
- 824-851, 869-896 MHz Frequency Restoration
-
- Tools Required: small Phillips screwdriver, small wire cutters.
-
- Procedure: With the power cord unplugged, remove the two rear
- cabinet screws holding the upper cover. Lift off the upper cover,
- being careful not to stretch the speaker leads. Examine the inner,
- right-hand-corner of the front panel to find two glass diodes, labelled
- D503 (upper diode) and D502 (lower diode).
-
- Using the clippers, very carefully snip the visible lead of the lower
- diode (D502) at its bend and slightly separate the cut ends. If it is
- ever necessary to send the radio back for warrenty repair, the diode
- leads should be carefully resoldered.
-
- Reassemble, plug in AC cord, turn on scanner, and press RESET.
-
- Keyboard Beep Delete
-
- With the top cover removed as described above, locate connector CN3,
- a 15-pin connector with colored wires at the front of the main circuit
- board. There are two precedures which will stop the beep tone from
- being heard through the speaker; read both to decide which procedure
- you want to follow.
-
- (1) Find the center grey wire coming from CN3 and cut it midway to
- disable the beep tone. You may wish to solder a resistor in series
- to reduce the beep volume, a trimpot to vary the volume of the beep
- tone, or a minature switch to choose between beep and no beep.
-
- (or)
-
- (2) Using a pair of needle-nose pliers, CAREFULLY pry the plug from CN3,
- revealing a row of pins. Locate the center pin (#8) which corresponds
- to the grey wire and bend it down flat, disabling the beep circuit.
- Reinsert the plug. The pin may be erected again later to restore the
- beep tone if desired.
-
- This completes the restoration procedure. Reattach the cover and replace
- the screws.
-
