BC200/205XLT CELLULAR RESTORATION
|
|
|
|
|
|
Note: It is unlawful to monitor cellular telephone conversations. It is
|
|
possible to monitor signals from the deleted ranges even without conversion.
|
|
Simply add 21.7 MHz to the deleted frequency and enter the higher (image)
|
|
frequency. Reception is virtually identical in strength to that which would be
|
|
heard on the deleted frequency.
|
|
|
|
The frequencies deleted at the factory may be restored, but the procedure must
|
|
not be attempted by anyone unfamiliar with electronic circuitry. Grove
|
|
Enterprises assumes no liability for damage caused by this procedure. The
|
|
modification will void your warranty.
|
|
|
|
TOOLS REQUIRED: Small Phillips screwdriver, small wire cutters.
|
|
|
|
1. Slide off the battery pack and remove the antenna from the scanner.
|
|
|
|
2. Using a small Phillips screwdriver, remove the two screws from the
|
|
back of the scanner, the two screws which hold the battery retaining spring at
|
|
the base and the spring itself.
|
|
|
|
3. Carefully pry the bottom of the rear cover from the radio and remove
|
|
the cover.
|
|
|
|
4. Locate the two small screws at the base of the circuit board and
|
|
remove them. Gently pull the front panel from the mainframe at the base and
|
|
separate them.
|
|
|
|
5. Locate the (64 pin quad flatpack) microprocessor IC labelled "UNIDEN
|
|
UC-1147" and the 10k ohm (brown-black-orange) leadless resistor positioned
|
|
above the letters "DEN" on the IC.
|
|
|
|
6. Using miniature wire cutters, cut the resistor body in two without
|
|
disturbing anything else near it. If the left solder pad comes loose, it may be
|
|
peeled from the board. Brush or blow away any residue. This completes the
|
|
restoration.
|
|
|
|
REASSEMBLY
|
|
|
|
7. Insert the top of the front panel into the slot under the
|
|
volume/squelch control panel and, noting carefully the alignment of the dual
|
|
inline connector at the bottom of the board with the mating socket, press the
|
|
front panel firmly into place. Be sure that the holes at the bottom of the
|
|
circuit board line up with the holes in the plastic standoffs below them.
|
|
Insert the two screws and gently tighten them.
|
|
|
|
8. Replace the back cover by inserting the top of the cover into the
|
|
slot under the volume/squelch control panel; press the cover into place, insert
|
|
and tighten the screws.
|
|
|
|
9. Reposition the battery retaining spring (slotted side toward notched
|
|
hole), insert the two remaining screws and gently but securely tighten them.
|
|
|
|
10. Slide the battery pack into place; switch the scanner on to make
|
|
sure the display comes on. If not, the battery is discharged or the dual-inline
|
|
connector was misaligned during assembly (see step 7).
|
|
|
|
Assuming the display comes on, press: MANUAL, 845.0, E; within two seconds, the
|
|
frequency 845.000 should appear on the display.
