Remove The CPU Board
1. Loosen the two phillips head screws on both sides of the database handle on the front panel of the
7000. (Refer to Figure 1 on page 6 of this manual.) Gently pull on the handle to slide the database
board out of the front of the unit.
If difficulty is encountered in removing the database, grasp the handle firmly and wiggle it from side
to side while pulling.
caution
DO NOT use a screwdriver or other device to remove the database board. Using any tool to pry
out the board will damage the bezel and database board.
2. The bottom panel is held in place with 10 screws: eight 3/16 inch screws and two 1/8 inch screws.
The 1/8 inch screws are marked in red. Note their location, then remove all ten screws to remove
the bottom panel.
3. The rear cover is attached to the unit housing with five flat-head screws. Remove these screws.
CAIITIOM
Do not remove the red-marked screw on the right cover. This screw does not secure the rear cover.
This screw is not as long as the others because there is not as much clearance at this location. If
you remove this screw, be sure to put the correct screw back in this location so as not to damage
the unit.
4. The rear cover is connected to the CPU and transfer boards. Slowly pull the rear cover out of the
unit housing until the boards are exposed approximately 1-1/2 inches.
5. A ribbon cable connects the solder side of the CPU board to the mother board. Disengage this
connector and slide the CPU board completely out of the unit's housing.
6. On the rear cover there are two pan-head screws located at either end of the 25 pin D-connector,
which secure the rear cover to the CPU board. Separate the CPU board and rear cover by first
removing these screws.
7. The transfer board is attached to the CPU board by a connector on the end of the board nearest the
front panel of the unit. Pull the transfer board from the CPU board using a gentle rocking motion.
Remove The Old .Tack
8. The shorting plug is mounted near the ROM chips. (Refer to Figure 7 on page 27.) Heat each
solder joint with the soldering iron until it melts. Remove the solder with the solder wick or solder
sucker.
9. When all five holes are free of solder, gently pull the jack free of the board. The pins may have to
be re-heated briefly to loosen them from any residual solder.
10. Remove the solder left in the five holes using the solder wick or solder sucker. Make sure that no
solder is left inside the unit.
