|
||
restores 825-845 and 870-890 mhz on models manufactured during 1989
|
||
(HI code date suffix) or later (bnc antenna connectors).
|
||
|
||
1. with power cord disconnected, remove the four cover screws. remove the
|
||
top cover only.
|
||
|
||
2. locate the SANYO ic (printed upside down with the front of the
|
||
radio facing you). a long row of solder pads just above the ic identifies
|
||
pins 1-32 of the microprocessor. pin 1 is the left most pad and pin 32 is
|
||
the right most pad. your mod will involve pins 19,20,26 and 27.
|
||
|
||
3. using a sharp pointed tool, cut the two traces leading to pin 26.
|
||
(both above and below).
|
||
|
||
4. solder-bridge pins 26 and 27 together.
|
||
|
||
5. solder-bridge one end of a 1/2" wire across the two vacant solder pads
|
||
adjacent to pins 19 and 20 (short the pins). solder the other end of
|
||
this wire to just opposite pin 26 (the other side of the cut trace and
|
||
the solder bridge you installed in step 4.
|
||
|
||
6. insert the power cord, turn the unit on, press MANUAL, 845., E; if
|
||
845.000 appears, the mod was sucessful. Reassemble. If ERROR appears,
|
||
recount the pins you modified and check the cut traces and solder
|
||
bridges.
