  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.



 WARRANTY REPAIR

 

Should it be necessary during the first year of ownership of your new

PRO-2006 to exercise your warrenty, it should be carefully double-boxed

(as you received it) and returned to Grove Enterprises. Be sure to

include a copy of the original bill to establish warranty

privileges.



You must prepay only shipping and insurance; return shipping and

insurance to you will be paid by the dealer.



Grove Enterprises, P.O. Box 98, 140 Dogbranch Road
