UNIDEN BC855XLT 100 CHANNEL MEMORY CHANNEL EXPANSION
Tools needed:
Phllips screwdriver,wire cutters,1/4 or 1/2 watt 4.7-22 ohms
resistor,small soldering pen 15-30 watt,small gauge resin
core solder.With the power cord disconnected and the bottom
edge of the scanner facing you,turn it over on a soft
surface to prevent scratching.
1) Remove the 5 phillips head cabinet screws and carefully
separate the cabinet.
2) grasping the speaker,(not the wires) carefully pull the
plug from its socket.Lay the cabinet halves side by side.
3) refer to the illustration and find the 3rd jumper in a
row at the top of the right-hand circuit board.Cut "A" and
bend it down as shown.

Note: If you have already performed the cellular restoration
(done by cutting lead of 4 and routing and soldering as
shown) simply solder the jumper to the same resistor lead
and move on to step 5,if not proceed to step 4.
4)Route the resistor under the lower lead of diode D201 and
the jumper lead.Solder points A and B carefully;do not use
excessive heat.If the jumper comes loose from beneath the
board,it will reattach when the solder cools.
5)Snip off and remove excess wire from the resistor leads;
plug the speaker lead back in place; reassemble cabinet. If
factory service is required,the resistor may be removed and
the jumper lead re-soldered.
Your scanner will now store 100 channels 01-100 in 5 banks
of 20 channels each.
